Hilliard (Eds.), Transitioning from pediatric to adult care in endocrinology (pp. 117-137). Cham, Switzerland: Springer. https://doi.org/10.1007/978-3-030-05045-0_6 Show abstract
Type 1 diabetes and type 2 diabetes are prevalent endocrine conditions, with over 25,000 youth newly diagnosed with diabetes each year. Late adolescence and young adulthood is a particularly risky time for youth with diabetes. In addition to the normative challenges experienced during this developmental period, most youth with diabetes also must transfer from pediatric to adult health care. This chapter reviews key developmental and psychosocial considerations that may influence diabetes management and evidence-based guidelines informing the treatment of transition-aged youth with type 1 diabetes or type 2 diabetes. Specific recommendations to support transition efforts at the patient, provider, and health-care system levels are presented, and key resources to facilitate developmentally tailored, continuous care for youth with diabetes are highlighted.

Objective. Our objective was to identify perceived barriers and strategies to improve primary care encounters, as reported by adults with autism spectrum disorder (ASD), caregivers of adults with ASD, and primary care providers (PCPs) treating adults with ASD.
Method. As part of a larger mixed-methods design, adults with ASD, caregivers, and PCPs (N = 78) in Los Angeles and Philadelphia completed surveys examining barriers to care and strategies to improve care.
Results. Multiple barriers to care were reported by adults with ASD and caregivers, including communication and sensory challenges. Adults with ASD and caregivers reported minimal use of strategies during primary care visits but indicated that those used were helpful during care. Expert PCPs reported using strategies more frequently than novice PCPs. All respondent groups endorsed that strategies had the potential to improve care in the future for adults with ASD.
Conclusion. Opportunities exist for occupational therapy collaboration in primary health care and primary care education to improve care for adults with ASD.

Reilly’s (1962) now deeply cherished statement that “man, through the use of his hands, as they are energized by mind and will, can influence the state of his own health” (p. 1) was followed a few years later with a question to current and future occupational therapy practitioners. In 1966, Reilly asked how the profession would respond to the challenges of an expanding knowledge base, accelerating health care costs, and escalating regulatory burden. Visionary Wilma West, a contemporary of Reilly’s, expanded on these themes by focusing on ways occupational therapy practitioners could leverage the breadth and depth of their practice to confront these challenges. These issues are now paramount in the primary care arena. An expanding body of literature, including the articles in a special section in this issue of the American Journal of Occupational Therapy, supports occupational therapy’s role as a vital part of the solution to contemporary health care challenges. Occupational therapy practitioners are educationally prepared and successfully poised through policy to engage in evidence-based practice in the primary care environment.
Wang, Y., Juliano, J. M., Liew, S.-L., McKinney, A. M., & Payabvash, S. (2019). Stroke atlas of the brain: Voxel-wise density-based clustering of infarct lesions topographic distribution. NeuroImage: Clinical, 24, 101981. https://doi.org/10.1016/j.nicl.2019.101981 Show abstract
Objective. The supply territories of main cerebral arteries are predominantly identified based on distribution of infarct lesions in patients with large arterial occlusion; whereas, there is no consensus atlas regarding the supply territories of smaller end-arteries. In this study, we applied a data-driven approach to construct a stroke atlas of the brain using hierarchical density clustering in large number of infarct lesions, assuming that voxels/regions supplied by a common end-artery tend to infarct together.
Methods. A total of 793 infarct lesions on MRI scans of 458 patients were segmented and coregistered to MNI-152 standard brain space. Applying a voxel-wise data-driven hierarchical density clustering algorithm, we identified those voxels that were most likely to be part of same infarct lesions in our dataset. A step-wise clustering scheme was applied, where the clustering threshold was gradually decreased to form the first 20 mother (>50 cm3) or main (1–50 cm3) clusters in addition to any possible number of tiny clusters (<1 cm3); and then, any resultant mother clusters were iteratively subdivided using the same scheme. Also, in a randomly selected 2/3 subset of our cohort, a bootstrapping cluster analysis with 100 permutations was performed to assess the statistical robustness of proposed clusters.
Results. Approximately 91% of the MNI-152 brain mask was covered by 793 infarct lesions across patients. The covered area of brain was parcellated into 4 mother, 16 main, and 123 tiny clusters at the first hierarchy level. Upon iterative clustering subdivision of mother clusters, the brain tissue was eventually parcellated into 1 mother cluster (62.6 cm3), 181 main clusters (total volume 1107.3 cm3), and 917 tiny clusters (total volume of 264.8 cm3). In bootstrap analysis, only 0.12% of voxels, were labelled as “unstable” — with a greater reachability distance in cluster scheme compared to their corresponding mean bootstrapped reachability distance. On visual assessment, the mother/main clusters were formed along supply territories of main cerebral arteries at initial hierarchical levels, and then tiny clusters emerged in deep white matter and gray matter nuclei prone to small vessel ischemic infarcts.
Conclusions. Applying voxel-wise data-driven hierarchical density clustering on a large number of infarct lesions, we have parcellated the brain tissue into clusters of voxels that tend to be part of same infarct lesion, and presumably representing end-arterial supply territories. This hierarchical stroke atlas of the brain is shared publicly, and can potentially be applied for future infarct location-outcome analysis.

Oral care experiences of Latino parents/caregivers with children with autism and with typically developing children. International Journal of Environmental Research and Public Health, 16(16), 2905. https://doi.org/10.3390/ijerph16162905 Show abstract
As a result of various barriers, several pediatric populations are at risk for poor oral health, including children with disabilities and children from under-represented populations, such as Latinos. To this end, this study aimed to better understand the factors that affect the oral health experiences of 32 Latino parents/caregivers from 18 families (n = 8 with a typically developing child and n = 10 with a child with Autism). Using a qualitative descriptive methodology, each family was interviewed twice. Interviews were audio-recorded, transcribed verbatim, and coded thematically to identify the individual, social, systemic, and culturally rooted factors contributing to oral health disparities in the families. The three themes that arose were “Why would I want to start trouble?”: Latino parents’ dissatisfaction with dental treatments, costs, and fear of the dentist and health care providers because of their ethnic minority status as key factors inhibiting receipt of dental care; “We have to put our children first”: prioritizing the oral care activities of their children over their own individual oral care needs; and “We always keep baking soda around”: familial and cultural influences on oral care habits. Understanding the oral health beliefs and experiences of Latino parents and caregivers of children with and without autism is critical for developing targeted prevention and intervention programs and reducing oral health disparities.

T., Van Horn, J. D., & Toga, A. W. (2019). The LONI QC System: A semi-automated, web-based and freely-available environment for the comprehensive quality control of neuroimaging data. Frontiers in Neuroinformatics, 13, 60. https://doi.org/10.3389/fninf.2019.00060 Show abstract
Quantifying, controlling, and monitoring image quality is an essential prerequisite for ensuring the validity and reproducibility of many types of neuroimaging data analyses. Implementation of quality control (QC) procedures is the key to ensuring that neuroimaging data are of high-quality and their validity in the subsequent analyses. We introduce the QC system of the Laboratory of Neuro Imaging (LONI): a web-based system featuring a workflow for the assessment of various modality and contrast brain imaging data. The design allows users to anonymously upload imaging data to the LONI-QC system. It then computes an exhaustive set of QC metrics which aids users to perform a standardized QC by generating a range of scalar and vector statistics. These procedures are performed in parallel using a large compute cluster. Finally, the system offers an automated QC procedure for structural MRI, which can flag each QC metric as being ‘good’ or ‘bad.’ Validation using various sets of data acquired from a single scanner and from multiple sites demonstrated the reproducibility of our QC metrics, and the sensitivity and specificity of the proposed Auto QC to ‘bad’ quality images in comparison to visual inspection. To the best of our knowledge, LONI-QC is the first online QC system that uniquely supports the variety of functionality where we compute numerous QC metrics and perform visual/automated image QC of multi-contrast and multi-modal brain imaging data. The LONI-QC system has been used to assess the quality of large neuroimaging datasets acquired as part of various multi-site studies such as the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Study and the Alzheimer’s Disease Neuroimaging Initiative (ADNI). LONI-QC’s functionality is freely available to users worldwide and its adoption by imaging researchers is likely to contribute substantially to upholding high standards of brain image data quality and to implementing these standards across the neuroimaging community.

Addressing diabetes in primary care: Hybrid effectiveness–implementation study of Lifestyle Redesign® occupational therapy. American Journal of Occupational Therapy, 73(5), 7305185020p1-7305185020p12. https://doi.org/10.5014/ajot.2019.037317 Show abstract
Importance. Primary health care is rapidly developing as an occupational therapy practice area. Yet, to date, little evidence supports occupational therapy’s feasibility and efficacy in primary care settings.
Objective. To report on the implementation and preliminary clinical outcomes of a Lifestyle Redesign® (LR)–occupational therapy (LR–OT) diabetes management intervention in a primary care clinic.
Design. Patients were randomized to be offered LR–OT or to a no-contact comparison group (data not reported). We assessed implementation outcomes using mixed methods.
Setting. Safety-net primary care clinic.
Participants. Clinic providers and staff; English- or Spanish-speaking clinic patients ages 18–75 yr with diabetes and a current hemoglobin A1c (HbA1c) ≥ 9.0%.
Intervention. Eight 1-hr individual sessions of LR–OT focused on diabetes management.
Outcomes and Measures. Clinical and health behavior outcomes were assessed via electronic medical record (EMR) review and self-report surveys of patients receiving LR–OT at initial evaluation and discharge. We assessed implementation outcomes (acceptability, appropriateness, feasibility, fidelity, efficiency, and timeliness) using patient and staff surveys, interviews, focus groups, and observations.
Results. Seventy-three patients were offered LR–OT: 51 completed one or more sessions, and 38 completed the program. Clinical outcomes among program completers indicate beneficial changes in HbA1c, diabetes self-care, and health status. Implementation challenges included a need for patient and staff education, securing adequate workspace, and establishing a referral process. Factors contributing to implementation success included strong buy-in from clinic leadership, colocation, and shared EMR documentation.
Conclusions and Relevance. LR–OT is a feasible approach to enhancing service delivery and clinical outcomes in primary care.
What This Article Adds. This study provides insight into factors that may create challenges or contribute to the success of implementing occupational therapy services within primary health care settings. In addition, this study provides preliminary evidence of occupational therapy’s effectiveness in improving clinical outcomes among ethnically diverse, low-income patients with diabetes in a safety-net primary care setting.

Importance. Sensory symptoms in people with autism spectrum disorder (ASD) are commonly reported by researchers. However, an often overlooked sensory aspect of ASD is sensory discrimination in general, and somatosensory discrimination in particular.
Objective. To examine what has and what has not yet been learned concerning the somatosensory discrimination abilities of people with ASD and to reveal gaps warranting further research.
Design. Scoping review of clinical studies published 1995–2017 located through searches of PsycNET, PubMed, ERIC, and Google Scholar. Inclusion criteria were English-language peer-reviewed studies with (1) participants diagnosed with ASD, (2) a specific somatosensory discrimination measure, and (3) a comparison group. No age or intellectual exclusion criteria were established; studies were excluded if they were theoretical or descriptive, did not incorporate a control group, focused only on neurology or genetics, or used simple threshold detection measures or somatosensory measures integrated with other measures. The final search yielded 12 comparative articles discussing tactile and proprioceptive discrimination in people with ASD.
Results. Overall, most results showed atypical somatosensory discrimination in people with ASD, especially among young children. The relationship between sensory discrimination abilities and other sensory symptoms and ASD symptoms is briefly discussed.
Conclusions and Relevance. Heterogeneous findings concerning somatosensory discrimination in people with ASD shed light on underlying mechanisms of these disorders and can contribute to improvement of occupational therapy intervention for this population.
What This Article Adds. The occupational therapy evaluation of people with ASD can benefit from addressing somatosensory discrimination and its contribution to other clinical symptoms. This type of assessment can help improve intervention strategies for people with ASD by promoting a focus on the effect of discrimination deficits on daily function.

Importance. Geriatric, interprofessional primary care training for occupational therapy students is needed.
Objective. To measure occupational therapy student–reported knowledge, attitudes, and skills after participation in interprofessional geriatric educational programs.
Design. Prospective, observational study with pre- and posttests for the three programs.
Participants. Fifty-nine entry-level and postprofessional occupational therapy master’s students.
Outcomes and Measures. Self-reported familiarity with other professionals’ roles, perceptions of interprofessional training, capabilities to conduct assessments, and attitudes of older adults.
Results. Students of the three programs (Interprofessional Geriatrics Curriculum [IPGC], Student Senior Partnership Program [SSPP], and Geriatric Assessment Program [GAP]) reported different improvements in familiarity of roles, capabilities of assessment, and Geriatric Attitudes Scale (GAS) scores. For example, IPGC and SSPP students had changes in total GAS score (3.91–4.08, p = .002, and 3.84–3.99, p = .003, respectively), but no change was found for GAP students (3.85–3.91, p = .523).
Conclusions and Relevance. More structured interprofessional education with older adults appeared to help prepare occupational therapy students to work on geriatric interprofessional teams in primary care.
What This Article Adds. This article expands on growing evidence to support occupational therapy’s role in primary care by addressing the need to train future generations to work on interprofessional geriatric primary care teams.
Cunningham, R., & Valasek, S. (2019). Occupational therapy interventions for urinary dysfunction in primary care: A case series. American Journal of Occupational Therapy, 73(5), 7305185040p1-7305185040p8. https://doi.org/10.5014/ajot.2019.038356 Show abstract
Urinary dysfunction is commonly reported in primary care contexts. A shortage of primary care providers is affecting access to relevant services. Occupational therapy practitioners work in primary care settings and typically address urinary dysfunction in an outpatient context. Evidence regarding the delivery of occupational therapy interventions for urinary dysfunction in primary care has been limited. In this study, 3 women received 9–14 occupational therapy sessions in a primary care setting to address urinary symptoms. Plan-of-care duration, assessments, and urinary dysfunction interventions were individualized to accommodate personal and environmental factors. Across all case-series participants, Canadian Occupational Performance Measure scores demonstrated clinically significant improvement. Mixed results were found for SF–36 health-related quality-of-life subscale scores. Assessment scores specific to urinary dysfunction decreased, indicating reduced symptom severity and functional impact. This article provides preliminary evidence regarding the feasibility of occupational therapy interventions addressing urinary dysfunction in primary care settings.

The objective of this study is to assess the impact of inflammatory arthritis on young adults’ activity participation using quantitative and qualitative methods to advance the field’s conceptualization of functional status. Young adults diagnosed with juvenile idiopathic arthritis or rheumatoid arthritis completed (1) the Health Assessment Questionnaire-Disability Index to determine functional status and (2) the day reconstruction method to explore experiential dimensions of function, including functional performance, functional satisfaction, and severity of arthritis symptoms during activities on the previous day. Bivariate analyses were conducted to examine relationships between functional status, experiential variables, and demographic variables. Open-ended questions were provided for participants to report ways that arthritis affected their participation that were not otherwise reflected within survey questions; responses were numerically coded using summative content analysis. Among 37 participants (24.8 ± 3.3 years old), 70% reported moderate-to-severe disability. On average, participants experienced pain, stiffness, or fatigue for more than 50% of their waking hours. Functional status significantly correlated with functional performance (r = − 0.39, p = 0.02) and satisfaction (r = − 0.39, p = 0.02), yet did not correlate with stiffness or fatigue severity or duration of symptoms throughout the day. Participants described strategies that improved their ability to participate in certain activities but reduced their overall quality of activity engagement and caused emotional distress. Young adults with arthritis may experience more significant functional limitations than previously reported. Traditional measures of functional assessment may not capture experiential components of activity that affect participation, such as severity of stiffness or fatigue or the duration of symptoms throughout the day.

Ito, K. L., Kim, H., & Liew, S.-L. (2019). A comparison of automated lesion segmentation approaches for chronic stroke T1‐weighted MRI data. Human Brain Mapping. Advance online publication. https://doi.org/10.1002/hbm.24729 Show abstract
Accurate stroke lesion segmentation is a critical step in the neuroimaging processing pipeline for assessing the relationship between poststroke brain structure, function, and behavior. Many multimodal segmentation algorithms have been developed for acute stroke neuroimaging, yet few algorithms are effective with only a single T1‐weighted (T1w) anatomical MRI. This is a critical gap because multimodal MRI is not commonly available due to time and cost constraints in the stroke rehabilitation setting. Although several attempts to automate the segmentation of chronic lesions on single‐channel T1w MRI have been made, these approaches have not been systematically evaluated on a large dataset. We performed an exhaustive review of the literature and identified one semiautomated and three fully automated approaches for segmentation of chronic stroke lesions using T1w MRI within the last 10 years: Clusterize, automated lesion identification (ALI), Gaussian naïve Bayes lesion detection (lesionGnb), and lesion identification with neighborhood data analysis (LINDA). We evaluated each method on a large T1w stroke dataset (N = 181). LINDA was the most computationally expensive approach, but performed best across the three main evaluation metrics (median values: dice coefficient = 0.50, Hausdorff's distance = 36.34 mm, and average symmetric surface distance = 4.97 mm). lesionGnb had the highest recall/least false negatives (median = 0.80). However, across the automated methods, many lesions were either misclassified (ALI: 28, lesionGnb: 39, LINDA: 45) or not identified (ALI: 24, LINDA: 23, lesionGnb: 0). Segmentation accuracy in all automated methods were influenced by size (small: worst) and stroke territory (brainstem, cerebellum: worst) of the lesion. To facilitate reproducible science, our analysis files have been made publicly available online.

Introduction. Kinesio tape is an alternative non-surgical treatment approach for addressing symptoms of carpal tunnel syndrome. The purpose of the study was to investigate individuals’ experiences with the dorsal application of Kinesio tape for carpal tunnel syndrome management and its impact on pain and function.
Method. The study design was a limited phenomenological design study embedded in a randomized controlled trial. Daily symptom journals and semi-structured interviews were completed with 15 participants who were purposefully recruited and randomly allocated to the intervention group of a single blind randomized controlled trial. Kinesio tape was applied dorsally on the affected forearm, wrist, and digits for a duration of two weeks. Transcribed data were analyzed using descriptive coding, coding schemes, and frequency charts to identify emerging themes.
Results. Three themes emerged: Kinesio tape was positively perceived to be effective on decreasing pain, increasing self-efficacy, and improving daily functional performance on tasks previously avoided or abandoned. The most common problem identified was maintaining Kinesio tape on the hands and fingers, to which the majority of participants expressed a desire to learn application.
Discussion. Results of this study suggest that Kinesio tape is a positively perceived intervention for decreasing pain and increasing function for individuals with carpal tunnel syndrome and warrants further consideration as an alternative conservative intervention for carpal tunnel syndrome.
Keywords. Carpal tunnel syndrome, Kinesio tape, qualitative, functional performance

Prevention and rehabilitation of musculoskeletal disorders in oral health care professionals: A systematic review. The Journal of the American Dental Association, 150(6), 489-502. https://doi.org/10.1016/j.adaj.2019.01.031 Show abstract
Background. The authors’ objective in this systematic review was to describe the evidence for preventive and rehabilitative interventions for musculoskeletal disorders in oral health care.
Types of Studies Reviewed. The authors conducted systematic search, screening, and eligibility processes to identify experimental, quasiexperimental, observational, and survey research studies in which the investigators either directly evaluated or predicted the effects of preventive or rehabilitative interventions on the reduction of musculoskeletal symptoms in oral health care professionals.
Results. The authors identified and screened 3,571 unique abstracts, assessed 256 full-text articles for eligibility, and included 34 articles in the review. Investigators in 17 experimental studies described the results of preventive or rehabilitation interventions and in 17 survey research studies predicted or correlated preventive or protective techniques to a reduction in musculoskeletal symptoms. The primary techniques evaluated in the studies included equipment modification, ergonomic training, and physical exercise.
Conclusions and Practical Implications. The evidence suggests that magnification loupes and indirect-vision techniques have a positive effect on the reduction of musculoskeletal symptoms. In terms of evaluating intervention efficacy, other techniques have mixed evidence or are limited by low-level study design.
Keywords. Ergonomics; injury prevention; musculoskeletal disorders; dentists; dental hygienists
Vourvopoulos, A., Pardo, O. M., Lefebvre, S., Neureither, M., Saldana, D., Jahng, E., & Liew, S.-L. (2019). Effects of a brain-computer interface with virtual reality (VR) neurofeedback: A pilot study in chronic stroke patients. Frontiers in Human Neuroscience, 13, 210. https://doi.org/10.3389/fnhum.2019.00210 Show abstract
Rehabilitation for stroke patients with severe motor impairments is burdensome and demanding because most of the current rehabilitation options require some volitional movement to train the affected side. However, research has shown that survivors of severe stroke may receive modest benefits from action observation, virtual reality (VR), and brain-computer interfaces (BCIs). These approaches have shown some success in strengthening key motor pathways thought to support motor recovery after stroke. The purpose of this study was to combine the principles of action observation, VR, and BCI in a platform called REINVENT and assess its effects on four chronic stroke patients across different levels of motor impairment. REINVENT acquires post-stroke EEG signals that indicate an attempt to move and drives the movement of a virtual avatar arm, allowing patient-driven action observation neurofeedback in VR. In addition, synchronous electromyography (EMG) data were also captured to monitor overt muscle activity. Our results show that this EEG-based BCI can be used by stroke survivors across a wide range of motor disabilities. Finally, individual results suggest that patients with more severe motor impairments benefit the most from EEG-based neurofeedback, while patients with more mild impairments may benefit more from EMG-based feedback, harnessing existing sensorimotor pathways. Future research is needed to confirm these findings in a larger and more diverse population.

Home telemedicine (CoYoT1 clinic): A novel approach to improve psychosocial outcomes in young adults with diabetes. The Diabetes Educator. Advance online publication. https://doi.org/10.1177/0145721719858080 Show abstract
Purpose. To assess the impact of a home telemedicine clinic model (CoYoT1 Clinic) on psychosocial and behavioral outcomes designed for young adults (YAs) with type 1 diabetes (T1D).
Methods. YAs self-selected to participate in the CoYoT1 Clinic or serve as a usual care control. CoYoT1 Clinic visits consisted of an individual appointment with a provider and a group appointment with other YAs with T1D using home telemedicine. Psychosocial and behavioral functioning was assessed by 4 measures: Diabetes Distress Scale, Self-Efficacy for Diabetes Scale, Self-Management of Type 1 Diabetes in Adolescence Scale, and Center for Epidemiologic Studies Depression Scale.
Results. Forty-two patients participated in the CoYoT1 Clinic and 39 patients served as controls. CoYoT1 participants reported lower levels of distress (P = .03), increased diabetes self-efficacy (P = .01), and improved ability to communicate with others about diabetes (P = .04) over the study period compared to controls. YA males in the control group reported increases in depressive symptoms (P = .03) during the study period, but CoYoT1 participants showed no changes.
Conclusion. Group home telemedicine for YAs with T1D positively affects diabetes distress, self-efficacy, and diabetes-specific communication. These positive findings have the potential to also affect the YAs’ long-term diabetes outcomes. Further investigation of the model is needed.
Wathugala, M., Saldana, D., Juliano, J. M., Chan, J., & Liew, S.-L. (2019). Mindfulness meditation effects on poststroke spasticity: A feasibility study. Journal of Evidence-Based Integrative Medicine. Advance online publication. https://doi.org/10.1177/2515690X19855941 Show abstract
This study examined the feasibility of an adapted 2-week mindfulness meditation protocol for chronic stroke survivors. In addition, preliminary effects of this adapted intervention on spasticity and quality of life in individuals after stroke were explored. Ten chronic stroke survivors with spasticity listened to 2 weeks of short mindfulness meditation recordings, adapted from Jon Kabat-Zinn’s Mindfulness-Based Stress Reduction course, in a pre/post repeated measures design. Measures of spasticity, quality of life, mindfulness, and anxiety, along with qualitative data from participants’ daily journals, were assessed. On average, participants reported meditating 12.5 days of the full 15 days (mean 12.5 days, SD 0.94, range 8-15 days). Seven of the 10 participants wrote comments in their journals. In addition, there were no adverse effects due to the intervention. Exploratory preliminary analyses also showed statistically significant improvements in spasticity in both the elbow (P = .032) and wrist (P = .023) after 2 weeks of meditation, along with improvements in quality of life measures for Energy (P = .013), Personality (P = .026), and Work/Productivity (P = .032). This feasibility study suggests that individuals with spasticity following stroke are able to adhere to a 2-week home-based mindfulness meditation program. In addition, preliminary results also suggest that this adapted, short mindfulness meditation program might be a promising approach for individuals with spasticity following stroke.

People spend most of their day in buildings, and a large portion of the energy in buildings is used to control the indoor environment for creating acceptable conditions for occupants. However, majority of the building systems are controlled based on a ‘one size fits all’ scheme which cannot account for individual occupant preferences. This leads to discomfort, low satisfaction and negative impacts on occupants’ productivity, health and well-being. In this paper, we describe our vision of how recent advances in Internet of Things (IoT) and machine learning can be used to add intelligence to an office desk to personalize the environment around the user. The smart desk can learn individual user preferences for the indoor environment, personalize the environment based on user preferences, and act as an intelligent support system for improving user comfort, health and productivity. We briefly describe the recent advances made in different domains that can be leveraged to enhance occupant experience in buildings and describe the overall framework for the smart desk. We conclude the paper with a discussion of possible avenues for further research.

Gamma tACS over the temporal lobe increases the occurrence of Eureka! moments. Scientific Reports, 9, 5778. https://doi.org/10.1038/s41598-019-42192-z Show abstract
The solution to a problem might manifest itself as a burst of unexpected, unpredictable clarity. Such Eureka! events, or Insight moments, are among the most fascinating mysteries of human cognition, whose neurophysiological substrate seems to include a role for oscillatory activity within the α and γ bands in the right parietal and temporal brain regions. We tested this hypothesis on thirty-one healthy participants using transcranial Alternating Current Stimulation (tACS) to externally amplify α (10 Hz) and γ (40 Hz) activity in the right parietal and temporal lobes, respectively. During γ-tACS over the right temporal lobe, we observed an increase in accuracy on a verbal insight task. Furthermore, electroencephalography (EEG) data revealed an increase in γ spectral power over bilateral temporal lobes after stimulation. Additionally, resting-state functional MRI data acquired before the stimulation session suggested a correlation between behavioral response to right temporal lobe tACS and functional connectivity of bilateral temporal lobes, in line with the bilateral increase in γ band revealed by EEG. Overall, results suggest the possibility of enhancing the probability of generating Eureka! moments in humans by means of frequency-specific noninvasive brain stimulation.

Patients are experts on their own lives and the ways in which an illness, injury, or disability affects their health, activity, and quality of life. With its longstanding foundations in participatory action research, patient engagement has been gaining momentum across health care and related research. This momentum is supported by investments from several key research and federal policy–related organizations, including the Patient-Centered Outcomes Research Institute, National Institutes of Health, and Agency for Healthcare Research and Quality. Occupational therapy practitioners are uniquely positioned to champion patient collaborations. In this article, we discuss ways in which patient perspectives can be embraced in occupational therapy research, and we share insights from a research planning collaborative with adolescents and young adults that was led by occupational therapy researchers.

Oral health is an important yet often neglected component of overall health, linked to heart disease, stroke, and diabetic complications. Disparities exist for many groups, including racial and ethnic minorities such as African Americans. The purpose of this study was to examine the potential factors that perpetuate oral health care disparities in African American children in the United States. A systematic search of three literature databases produced 795 articles; 23 articles were included in the final review. Articles were analyzed using a template coding approach based on the social ecological model. The review identified structural, sociocultural, and familial factors that impact the ability of African Americans to utilize oral care services, highlighting the importance of the parent/caregiver role and the patient–provider relationship; policy-level processes that impact access to quality care; the value of autonomy in treatment and prevention options; and the impact of sociocultural factors on food choices (e.g., food deserts, gestures of affection). In conclusion, oral health care remains an underutilized service by African American children, despite increasing access to oral care secondary to improvements in insurance coverage and community-based programs.

Objective. In this study, we examined if 6–9 Hz jaw tremor, an indirect indicator of Periodontal Mechanoreceptor (PMR) activity, is different in bruxists compared to healthy participants during production of a low-level constant bite force.
Methods. Bite force and surface EMG from the masseter muscle were recorded simultaneously as participants (13 patients, 15 controls) held a force transducer between the upper and lower incisors very gently.
Results. Tremor in 6–9 Hz band for bruxists was greater on average compared to controls, but the difference was not significant, both for force recordings and EMG activity.
Conclusions. The low effect sizes measured with the current protocol contrast highly with those of our previous study, where larger, dynamic bite forces were used, and where jaw tremor was markedly different in bruxists compared with controls.
Significance. We have now gained important insight into the conditions under which abnormal jaw tremor can be elicited in bruxism. From a scientific standpoint, this is critical for understanding the ‘abnormality’ of PMR feedback in bruxism. From a clinical perspective, our results represent progress towards the development of an optimal protocol in which jaw tremor can serve as a biological marker of bruxism.

Study Design. Mapping review.
Introduction. Although published literature and evidence to support medical practice is becoming more abundant, it is not known how well available evidence supports the full spectrum of hand therapy practice.
Purpose of the Study. The aim of this mapping review was to identify strengths and/or gaps in the available literature as compared with the hand therapy scope of practice to guide future research.
Methods. A systematic search and screening was conducted to identify evidence published from 2006 to 2015. Descriptive data from 191 studies were extracted, and the diagnoses, interventions, and outcomes used in the literature were compared with the hand therapy scope of practice.
Results. Osteoarthritis, tendon surgeries, and carpal tunnel syndrome were most frequently studied. Exercise, education, and orthotic interventions were most common, each used in more than 100 studies; only 12 studies used activity-based interventions. Primary outcome measures included range of motion, pain/symptoms, strength, and functional status.
Discussion. Abundant high-quality research exists for a portion of the hand therapy scope of practice; however, there is a paucity of evidence for numerous diagnoses and interventions.
Conclusions. More evidence is needed for complex diagnoses and activity-based interventions as well as behavioral and quality-of-care outcomes.
Level of Evidence. Not applicable.

Purpose. Oral health is important to physical and psychological health. Individuals with autism spectrum disorder (ASD) experience significant oral care challenges, but little research exists that examines efficacious interventions to improve care. The purpose of this study was to qualitatively explore parental and dentist reports of successful strategies implemented during dental care with children with ASD.
Methods. Focus groups were conducted with parents of children with ASD (N = two groups) and dentists treating children with ASD (N = two groups). Focus group transcripts were transcribed verbatim and analyzed using a thematic analysis approach.
Results. Three key themes were identified from the parent focus groups: (1) what makes a good dentist; (2) flexibility and techniques—strategies used by the dentist; and (3) preparation—strategies for parents and caregivers of children with ASD. Four themes emerged from the dentist groups: (1) parents know best; (2) practice; (3) flexibility; and (4) a network of colleagues. Areas of overlap between the parents and dental providers included the importance of preparation, necessity of flexibility and creativity, and value of collaboration.
Conclusions. Our findings provide insight into techniques perceived by parents and dental providers to facilitate successful dental encounters for children with ASD.

Journal of Spinal Cord Medicine, 42(1), 2–19. https://doi.org/10.1080/10790268.2017.1313931 Show abstract
Context/Objective. Medically serious pressure injuries (MSPrIs), a common complication of spinal cord injury (SCI), have devastating consequences on health and well-being and are extremely expensive to treat. We aimed to test the efficacy of a lifestyle-based intervention designed to reduce incidence of MSPrIs in adults with SCI.
Design. A randomized controlled trial (RCT), and a separate study wing involving a nonrandomized standard care control group.
Setting. Rancho Los Amigos National Rehabilitation Center, a large facility serving ethnically diverse, low income residents of Los Angeles County.
Participants. Adults with SCI, with history of one or more MSPrIs over the past 5 years: N=166 for RCT component, N=66 in nonrandomized control group.
Interventions. The Pressure Ulcer Prevention Program, a 12-month lifestyle-based treatment administered by healthcare professionals, largely via in-home visits and phone contacts.
Outcome Measures. Blinded assessments of annualized MSPrI incidence rates at 12 and 24 months, based on: skin checks, quarterly phone interviews with participants, and review of medical charts and billing records. Secondary outcomes included number of surgeries and various quality-of-life measures.
Results. Annualized MSPrI rates did not differ significantly between study groups. At 12 months, rates were .56 for intervention recipients, .48 for randomized controls, and .65 for nonrandomized controls. At follow-up, rates were .44 and .39 respectively for randomized intervention and control participants.
Conclusions. Evidence for intervention efficacy was inconclusive. The intractable nature of MSPrI threat in high-risk SCI populations, and lack of statistical power, may have contributed to this inability to detect an effect.

OTJR: Occupation, Participation and Health, 39(1), 5-13. https://doi.org/10.1177/1539449218762728 Show abstract
Older, rural-dwelling Latinos face multiple health disparities. We describe the protocol of a pilot study of a community health worker–occupational therapist-led lifestyle program, ¡Vivir Mi Vida! (¡VMV!), designed for delivery in primary care and adapted for late-midlife, Latino rural-living patients. Using mixed methods, we collected feasibility, acceptability, and preliminary efficacy data on ¡VMV!. Forty 50- to 64-year-old Latinos participated in a 16-week lifestyle intervention led by a community health worker–occupational therapist team. We conducted pre- and post-intervention assessments to evaluate the efficacy of ¡VMV! in improving psychosocial and clinical health outcomes. Focus groups and interviews were held post-intervention with participants and key stakeholders to assess feasibility and acceptability. This is the first trial designed to evaluate a lifestyle intervention that includes collaboration between occupational therapists and community health workers within primary care. The detailed description of methodology promotes research transparency and reproducibility of a community health worker–occupational therapist-led lifestyle intervention.

Background. Median nerve cross-sectional area (CSA) is the primary sonographic parameter for assessing and diagnosing median nerve pathology, such as carpal tunnel syndrome. However, variability in the sensitivity of diagnostic thresholds exists, which may be due to a lack of standardized normative reference values. Current estimates of normal median nerve CSA stem largely from small studies using a local pool of healthy controls. A systematic review and meta-analysis will be conducted to identify all available data for median nerve CSA in healthy, asymptomatic individuals to create a comprehensive set of normative reference values.
Methods. Articles that include sonographic measures of median nerve CSA will be identified through a rigorous search of published evidence, a hand search through tables of contents of key journals, and the gray literature, including ClinicalTrials.gov and conference abstracts. Each abstract and full text will be reviewed by multiple raters to identify studies from 2000 to present that include original data. Any study that provides median nerve CSA values from healthy individuals will be included (e.g., reference value study, control participants in a diagnostic study). Studies will be assessed for quality using a modified version of the National Institute of Health Study Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, with primary focus on the use of a detailed and acceptable image acquisition and analysis protocol. Using data from included studies, reference values will be calculated for median nerve CSA by anatomical regions, including the distal forearm, wrist, and carpal tunnel at the level of the pisiform. Reference values will be stratified by gender, ethnicity, and age based upon the specificity of the data provided by the included articles.
Discussion. A comprehensive set of normative reference values of median nerve CSA will reduce variability across studies, allowing future research to more accurately evaluate and establish diagnostic thresholds. Additionally, normative values can serve as a reference for evaluating treatment outcomes and provide a means to investigate and understand minor nuances in CSA changes that may be indicative of preclinical stages of median nerve pathology.

Factors protecting against pressure injuries in medically underserved adults with spinal cord injury: A qualitative study. Topics in Spinal Cord Injury Rehabilitation, 25(1), 31-40. https://doi.org/10.1310/sci2501-31 Show abstract
Background. Pressure injuries negatively impact quality of life and participation for individuals with spinal cord injury (SCI).
Objective. To examine the factors that may protect against the development of medically serious pressure injuries in adults with SCI.
Methods. A qualitative analysis was conducted using treatment notes regarding 50 socioeconomically disadvantaged individuals who did not develop medically serious pressure injuries during a 12-month pressure injury prevention intervention program.
Results. Eight types of potentially protective factors were identified: meaningful activity, motivation to prevent negative health outcomes, stability/resources, equipment, communication and self-advocacy skills, personal traits, physical factors, and behaviors/activities.
Conclusions. Some protective factors (e.g., personal traits) may be inherent to certain individuals and nonmodifiable. However, future interventions for this population may benefit from a focus on acquisition of medical equipment and facilitation of sustainable, health-promoting habits and routines. Substantive policy changes may be necessary to facilitate access to adequate resources, particularly housing and equipment, for socioeconomically disadvantaged individuals with SCI. Further research is needed to understand the complex interplay of risk and protective factors for pressure injuries in adults with SCI, particularly in underserved groups.

Longitudinal assessment of stability of sensory features in children with autism spectrum disorder or other developmental disabilities. Autism Research, 12(1), 100–111. https://doi.org/10.1002/aur.2008 Show abstract
Prior research on the stability of sensory processing problems in children with autism spectrum disorder (ASD) or other developmental disabilities (DD) has produced inconsistent results. We employed a longitudinal study design to assess the stability of three clinical sensory response patterns: hyporesponsiveness; hyperresponsiveness; and sensory interests, repetitions, and seeking behaviors (SIRS). Parents of children with ASD (n = 55) or DD (n = 35) responded to sensory questionnaires at two time points (T1 and T2) separated by 3.3 years on average, with the children aged 2–12 years (M = 5.69 ± 2.46) at the first assessment. For each sensory response pattern, regression analysis revealed that, for both ASD and DD groups, scores at T1 were strong predictors of scores at T2. Over the longitudinal assessment interval, there was a significant mean decline in severity for SIRS in both groups and for hyporesponsiveness in the ASD group. Parental estimates of the amount of therapy services received were positively associated with the severity of sensory features at T2, an outcome that may result from increased intervention dosages being administered to children who fail to improve over time. The results are discussed in terms of person‐centered and environmental considerations, which, in combination, have the capacity to affect stability outcomes for sensory features.

A qualitative analysis of pressure injury development among medically underserved adults with spinal cord injury. Disability and Rehabilitation. Advance online publication. https://doi.org/10.1080/09638288.2018.1552328 Show abstract
Purpose. Medically underserved adults with spinal cord injury (SCI) remain at high risk of incurring medically serious pressure injuries even after receiving education in prevention techniques. The purpose of this research is to identify circumstances leading to medically serious pressure injury development in medically underserved adults with SCI during a lifestyle-based pressure injury prevention program, and provide recommendations for future rehabilitation approaches and intervention design.
Methods. This study entailed a qualitative secondary case analysis of treatment notes from a randomized controlled trial. Participants were 25 community-dwelling, medically underserved adults with SCI who developed medically serious pressure injuries during the course of the intervention of the RCT.
Results and conclusions. Among the 25 participants, 40 unique medically serious pressure injuries were detected. The six themes related to medically serious pressure injury development were: (1) lack of rudimentary knowledge pertaining to wound care; (2) equipment and supply issues; (3) comorbidities; (4) non-adherence to prescribed bed rest; (5) inactivity; and (6) circumstances beyond the intervention’s reach. Together, these factors may have undermined the effectiveness of the intervention program. Modifications, such as assessing health literacy levels of patients prior to providing care, providing tailored wound care education, and focusing on equipment needs, have potential for altering future rehabilitation programs and improving health outcomes.

Musculoskeletal sonography is being widely used for evaluation of structures within the carpal tunnel. While some anatomical variants, such as bifurcated median nerves and persistent median arteries, have been well documented, limited literature describes the sonographic appearance of aberrant muscle bellies within the carpal tunnel. Multiple examples of the sonographic appearance of flexor digitorum superficialis and lumbrical muscle bellies extending into the carpal tunnel are provided. Techniques for static image acquisition and analysis are discussed, and the use of dynamic imaging to confirm which specific muscle belly is involved is described. Knowledge of the potential presence of muscle bellies in these images and ability to identify these structures is vital to avoid misclassification or misdiagnosis as abnormal pathology. The case examples are situated among current published evidence regarding how such anomalies may be related to the development of pathologies, such as carpal tunnel syndrome.

Readmissions to health care facilities are undesirable outcomes that indicate the quality of the care transitions. Although there is a growing evidence-base for preventing readmissions, the focus has been on acute care. Postacute care (PAC) patients are often excluded from these studies, and thus there is limited evidence guiding practitioners’ efforts to facilitate an effective community transition after PAC rehabilitation. To provide direction for PAC research and clinical practice, this scoping review summarizes current community transition interventions and identifies practices that facilitate successful community discharge. Thirteen care processes emerged from 35 studies, of which 5 were included in at least 60% of the studies, including coaching on the care transition process, medical self-management, medication self-management, scheduling follow-up medical services, and telephone follow-up. These findings can inform the development, evaluation, and implementation of PAC community transition interventions.

Screening tools have given us the opportunity to identify risk symptoms of autism spectrum disorder (ASD) in infants prior to the full expression of symptoms when a definitive diagnosis can be made. Identification of ASD risk via community screening and surveillance is particularly important for the estimated 89% of infants without known genetic risk factors (such as an older sibling with ASD) who will eventually be diagnosed with ASD. Based on the application of a transactional model of development to infants at-risk for ASD, parent-implemented very early interventions have the potential to attenuate the expression of ASD symptoms in these infants and improve outcomes. In this chapter, we will (1) discuss what is known about identification of infants who are at-risk for ASD through community screening, (2) highlight the research to date examining use of parent-implemented very early interventions for infants who were identified as at-risk for ASD via community screening, and (3) offer insight into some of the advantages and obstacles in intervening with this population based on our own research experiences and those of our colleagues who have done similar work.

Medication non-adherence occurs in more than half of children with chronic conditions. Unfortunately, most strategies for improving adherence have had limited success in the pediatric population highlighting the need for novel interventions that establish healthy self-management habits for children and adolescents. In this paper we discuss innovative strategies to improve adherence by embedding a medical regimen within a pet care routine, thereby capitalizing on the benefits of a structured habit while providing opportunities for development of autonomy in children and fostering collaborative parent interactions.

Background. Children with autism spectrum disorder (ASD) and other developmental disabilities (DD) exhibit sensory features that differ from their typically developing peers. Prior cross-sectional research has demonstrated significant associations between elevated sensory features and lower adaptive behavior scores, yet there is limited prospective research examining longitudinal associations.
Aims. To examine the longitudinal prediction of early sensory response patterns (i.e., hyperresponsiveness, hyporesponsiveness, and sensory interests, repetitions, and seeking behaviors) to later adaptive behavior outcomes in children with ASD and DD.
Methods and procedures. Children with ASD (n = 51) and DD (n = 30) were seen at two time points (Time 1: M(SD) = 5.6(2.5) years; Time 2: M(SD) = 9.0(2.2) years). We used a series of regression models with both observational and parent-report measures of sensory response patterns, and including group interactions.
Outcomes and results. All three sensory response patterns significantly predicted aspects of adaptive behaviors, with some differences based on assessment format and diagnostic group. Across groups and sensory patterns, we found some evidence that elevated sensory features early in childhood predicted lower adaptive behavior skills later in childhood.
Conclusions and implications. Sensory features may interfere with development of adaptive behaviors, suggesting a need for effective interventions addressing sensory features early in development.

Evaluation of ¡Vivir Mi Vida! to improve health and wellness of rural-dwelling, late middle-aged Latino adults: Results of a feasibility and pilot study of a lifestyle intervention. Primary Health Care Research & Development, 19, 448-463. https://doi.org/10.1017/S1463423617000901 Show abstract
The aim of this study was to determine the feasibility and efficacy of a culturally tailored lifestyle intervention, ¡Vivir Mi Vida! (Live My Life!). This intervention was designed to improve the health and well-being of high risk late middle-aged Latino adults and to be implemented in a rural primary care system.
Background. Rural-dwelling Latino adults experience higher rates of chronic disease compared with their urban counterparts, a disparity exacerbated by limited access to healthcare services. Very few lifestyle interventions exist that are both culturally sensitive and compatible for delivery within a non-metropolitan primary care context.
Methods. Participants were 37 Latino, Spanish-speaking adults aged 50–64-years-old, recruited from a rural health clinic in the Antelope Valley of California. ¡Vivir Mi Vida! was delivered by a community health worker-occupational therapy team over a 16-week period. Subjective health, lifestyle factors, and cardiometabolic measures were collected pre- and post-intervention. Follow-up interviews and focus groups were held to collect information related to the subjective experiences of key stakeholders and participants.
Findings. Participants demonstrated improvements in systolic blood pressure, sodium and saturated fat intake, and numerous patient-centered outcomes ranging from increased well-being to reduced stress. Although participants were extremely satisfied with the program, stakeholders identified a number of implementation challenges. The findings suggest that a tailored lifestyle intervention led by community health workers and occupational therapists is feasible to implement in a primary care setting and can improve health outcomes in rural-dwelling, late middle-aged Latinos.

The advancing social-communication and play (ASAP) intervention was designed as a classroom-based intervention, in which the educational teams serving preschool-aged children with autism spectrum disorder are trained to implement the intervention in order to improve these children’s social-communication and play skills. In this 4-year, multi-site efficacy trial, classrooms were randomly assigned to ASAP or a business-as-usual control condition. A total of 78 classrooms, including 161 children, enrolled in this study. No significant group differences were found for the primary outcomes of children’s social-communication and play. However, children in the ASAP group showed increased classroom engagement. Additionally, participation in ASAP seemed to have a protective effect for one indicator of teacher burnout.

Objective. This study examined post-acute care (PAC) rehabilitation practitioner’s perspectives on communication.
Method. This is a secondary data analysis of a larger qualitative study, which included PAC rehabilitation provider (n = 99) focus groups that were held in a purposive sample of 13 skilled nursing facilities (SNFs).
Results. Participants emphasized the importance of bidirectional communication between rehabilitation and nursing. Three themes were identified: (a) communication between rehabilitation practitioners and registered nurses or licensed practical nurses, (b) communication between rehabilitation practitioners and certified nursing assistants, and (c) communication between rehabilitation practitioners and nursing leaders. Two subthemes within each of the three themes were further characterized to understand how information was exchanged: (a) static communication and (b) action-oriented communication.
Conclusion. Our findings highlight opportunities for better communication in PAC between rehabilitation practitioners and nursing and thus lay a foundation for future efforts to improve care coordination through enhancing interdisciplinary communication.

As our health care system continues to change, so do the opportunities for occupational therapy. This article provides an update to a 2012 Health Policy Perspectives on this topic. We identify new initiatives and opportunities in primary care, explore common challenges to integrating occupational therapy in primary care environments, and highlight international works that can support our efforts. We conclude by discussing next steps for occupational therapy practitioners in order to continue to progress our efforts in primary care.

The link between the local structure of the primary motor cortex and motor function has been well documented. However, motor function relies on a network of interconnected brain regions and the link between the structural properties characterizing these distributed brain networks and motor function remains poorly understood. Here, we examined whether distributed patterns of brain structure, extending beyond the primary motor cortex can help classify two forms of motor function: corticospinal excitability and intracortical inhibition. To this effect, we recorded high-resolution structural magnetic resonance imaging scans in 25 healthy volunteers. To measure corticospinal excitability and inhibition in the same volunteers, we recorded motor evoked potentials (MEPs) elicited by single-pulse transcranial magnetic stimulation and short-interval intracortical inhibition (SICI) in a separate session. Support vector machine (SVM) pattern classification was used to identify distributed multi-voxel gray-matter areas, which distinguished subjects who had lower and higher MEPs and SICIs. We found that MEP and SICI classification could be predicted based on a widely distributed, largely non-overlapping pattern of voxels in frontal, parietal, temporal, occipital, and cerebellar regions. Thus, structural properties distributed over the brain beyond the primary motor cortex relate to motor function.

The everyday landscape of occupational therapy (OT) in oncology is underexplored, hindering targeted improvements. The purpose of the present study was to identify the OT interventions commonly provided and reimbursed in oncology. A survey utilizing snowball sampling was disseminated online to OT working in oncology care; 167 surveys were received from 21 states in the United States. Results found that over 90% of therapists reported focusing on physical impairment, weakness, fatigue, and activities of daily living. Interventions for emotional/social support, self‐advocacy, quality of life, lifestyle management, and cognitive impairment were not directly billed. More than 90% of therapists reported that, in the absence of barriers, they would address quality of life, emotional difficulties, lifestyle management, and home safety. Overall, the findings suggested that OT in the United States primarily provide physical interventions for oncology patients. However, they also provide psychosocial services and client/caregiver education, but often do not bill directly for this care. Reimbursement structures should be modified to allow for the direct billing of mental/psychosocial and educational interventions in OT for cancer care.
Failla, M. D., Moana-Filho, E. J., Essick, G. K., Baranek, G. T., Rogers, B. P., & Cascio, C. J. (2018). Initially intact neural responses to pain in autism are diminished during sustained pain. Autism, 22(6), 669-683. https://doi.org/10.1177/1362361317696043 Show abstract
Pain assessments typically depend on self-report of the pain experience. Yet, in individuals with autism spectrum disorders, this can be an unreliable due to communication difficulties. Importantly, observations of behavioral hypo- and hyperresponsivity to pain suggest altered pain sensitivity in autism spectrum disorder. Neuroimaging may provide insight into mechanisms underlying pain behaviors. The neural pain signature reliably responds to painful stimulation and is modulated by other outside regions, affecting the pain experience. In this first functional magnetic resonance imaging study of pain in autism spectrum disorder, we investigated neural responses to pain in 15 adults with autism spectrum disorder relative to a typical comparison group (n = 16). We explored temporal and spatial properties of the neural pain signature and its modulators during sustained heat pain. The two groups had indistinguishable pain ratings and neural pain signature responses during acute pain; yet, we observed strikingly reduced neural pain signature response in autism spectrum disorder during sustained pain and after stimulus offset. The posterior cingulate cortex, a neural pain signature modulating region, mirrored this late signal reduction in autism spectrum disorder. Intact early responses, followed by diminished late responses to sustained pain, may reflect altered pain coping or evaluation in autism spectrum disorder. Evidence of a dichotomous neural response to initial versus protracted pain may clarify the coexistence of both hypo- and hyperresponsiveness to pain in autism spectrum disorder.

The primary aim of this study was determining Grade 1 cognitive predictors of students at risk for writing disabilities in Grades 2 through 4. Applying cognitive measures selected to align with theoretical and empirical models of writing, tasks were administered to Grade 1 students assessing fine-motor, linguistic, and executive functions: 84 at risk (bottom quartile for age-base expectations) and 54 typically developing. A model with individual predictors was compared to a previously developed latent trait model to determine the relative predictive worth of each approach. Data analysis primarily involved stepwise logistic regression. Results revealed that the individual measures of orthographic choice, working memory, inhibitory control, visual memory recognition, and planning all were significant predictors of at risk status in Grades 2 through 4. The latent trait model also fared well but did not account for the same amount of variance as any of the individual measurement models for any of the grades. The findings lay the foundation for an empirically based approach to cognitive assessment in Grade 1 for identifying potential at-risk students in later elementary grades and suggest potential underlying neurocognitive abilities that could be employed with educational interventions for students with later-emerging writing disabilities.

Psychosocial and behavioral correlates of A1C and quality of life among young adults with diabetes. The Diabetes Educator, 44(6), 489–500. https://doi.org/10.1177/0145721718804170 Show abstract
Purpose. The purpose of this study was to evaluate relationships between behavioral and psychosocial constructs, A1C, and diabetes-dependent quality of life (DQoL) among low-socioeconomic status, ethnically diverse young adults with diabetes.
Methods. Using baseline data of 81 participants in the Resilient, Empowered, Active Living (REAL) randomized controlled trial, behavioral, cognitive, affective, and experiential variables were correlated with A1C and DQoL while adjusting for demographic characteristics, and these relationships were examined for potential effect modification.
Results. The data indicate that depressive symptoms and satisfaction with daily activities are associated with both A1C and DQoL, while diabetes knowledge and participation in daily activities are associated with neither A1C nor DQoL. Two constructs, diabetes distress and life satisfaction, were associated with DQoL and were unrelated to A1C, while 2 constructs, self-monitoring of blood glucose and medication adherence, were associated with A1C but unrelated to DQoL. These relationships were largely unchanged by adjusting for demographic characteristics, while numerous effect modifications were found.
Conclusion. The data suggest that when tailoring interventions, depressive symptoms and satisfaction with daily activities may be particularly fruitful intervention targets, as they represent modifiable risk factors that are associated with both A1C and DQoL.

The goal of this paper is to examine the psychometric properties of a live-coded behavioral measure of joint attention, the Attention-Following and Initiating Joint Attention Protocol (JA Protocol), in order to assist researchers and clinicians in identifying when this measure may meet their joint attention assessment needs. Data from 260 children with autism spectrum disorder, developmental delay, or typical development between the ages of 2 and 12 years were used to evaluate this measure using quality standards for measurement. Overall, the JA Protocol demonstrated good psychometric properties. Recommendations and limitations for use of this measure based on psychometric analysis results are reported.

Delivering high quality hip fracture rehabilitation: The perspective of occupational and physical therapy practitioners. Disability and Rehabilitation, 40(6), 646-654. https://doi.org/10.1080/09638288.2016.1273973 Show abstract
Aim. The majority of post-acute hip fracture rehabilitation in the US is delivered in skilled nursing facilities (SNFs). Currently, there are limited guidelines that equip occupational and physical therapy practitioners with a summary of what constitutes evidence-based high quality rehabilitation. Thus, this study aimed to identify rehabilitation practitioners' perspectives on the practices that constitute high quality hip fracture rehabilitation.
Methods. Focus groups were conducted with 99 occupational and physical therapy practitioners working in SNFs in southern California. Purposive sampling of facilities was conducted to capture variation in key characteristics known to impact care delivery for this patient population (e.g., financial resources, staffing, and patient case-mix). Questions aimed to elicit practitioners' perspectives on high quality hip fracture rehabilitation practices. Each session was audio-recorded and transcribed. Data were systematically analyzed using a modified grounded theory approach.
Results. Seven themes emerged: objectives of care; first 72h; positioning, pain, and precautions; use of standardized assessments; episode of care practices; facilitating insight into progress; and interdisciplinary collaboration.
Conclusions. Clinical guidelines are critical tools to facilitate clinical decision-making and achieve desired patient outcomes. The findings of this study highlight the practitioners' perspective on what constitutes high quality hip fracture rehabilitation. This work provides critical information to advance the development of stakeholder-driven rehabilitation clinical guidelines. Future research is needed to verify the findings from other stakeholders (e.g., patients), ensure the alignment of our findings with current evidence, and develop measures for evaluating their delivery and relationship to desired outcomes. Implications for Rehabilitation This study highlights occupational and physiotherapy therapy practitioners' perspectives on the cumulative best practices that reflect high quality care, which should be delivered during hip fracture rehabilitation. While this study was limited to two professions within the broader interdisciplinary team, consistently occupational and physiotherapy therapy practitioners situated their role and practices within the team, emphasizing that high quality care was driven by collaboration among all members of the team as well as the patient and caregivers. Future research needs to evaluate the (a) frequency at which these practices are delivered and the relationship to patient-centered outcomes, and (b) perspectives of rehabilitation practitioners working in other PAC settings, patients, caregivers, as well as the other members of the interdisciplinary PAC team.

Evidence suggests that oral narrative skills are a linguistic strength for African American children, yet few studies have examined how these skills are associated with reading for African American boys and girls. The current study uses longitudinal data of a sample of 72 African American 4-year-olds to examine how preschool oral narrative skills predict reading from first through sixth grades and explores differences by gender. Findings indicate that although girls demonstrated stronger narrative skills, their narrative skills did not moderate change in reading. For boys, narrative skills moderated change in reading over time such that as preschool narrative skills increased, their reading scores showed greater change over time. Educational implications and directions for future research are discussed.

There are a number of recent US news media reports of children and youth with autism becoming lost, injured, or even dying while taking public school transportation, yet research on this problem is scarce. This ethnographic study examines the experiences of 14 parents whose children with autism take public school transportation in Los Angeles County. We present two case studies of children with autism being “lost” while in transit from school to home on the bus to (1) describe how the situation was experienced, responded to, and managed by the parents; (2) consider three interrelated themes that emerged from interviews with 14 parents, related to children’s safety, independence, and participation, across multiple contexts and analytic levels; and (3) discuss the findings in relation to US news media reports of incidents involving children with autism on school buses to identify specific weaknesses in school transportation infrastructure, particularly in the context of privatization, that create conditions in which children with autism can “fall through the cracks” in potentially life-threatening ways. We argue that there is a critical need to address transportation accessibility for individuals on the autism spectrum to ensure their safety and support their independence and community participation.

Purpose. Participation is widely recognized as an important outcome for rehabilitation. However, it lacks a universally accepted definition. The purpose of this review is to synthesize the literature about participation in rehabilitation in order to clarify the term and increase its usefulness for rehabilitation providers and researchers.
Methods. We undertook an interpretive synthesis of the literature, drawing from a broad and varied selection of the vast number of publications on the subject of participation. The search and analysis was iterative and continued until saturation of themes was achieved.
Results and Conclusions. Seventy-six articles were included in our analysis. We argue that three essential dimensions — performance, subjective experience, and interpersonal connection — constitute participation. We further divide participation into community-based and interventional contexts. Interventional participation is circumscribed by the treatment setting, whereas community-based encompasses all other areas. Participation in either interventional or community-based contexts is largely determined by the available opportunities from which a person can choose, with such opportunities affected by conditions that are either internal or external to the individual. As defined in this framework, participation is not inherently good or bad; rather, its effect is determined by a person's unique life circumstances and the impact may not always be apparent. We posit this model as a resource for future research as well as clinical reasoning.
Implications for Rehabilitation. The often tacit assumption that increasing participation is a desirable outcome needs to be challenged and considered in each patient's life situation. Treatment settings constitute a unique context in which patients participate. Intervention goals should be clearly connected with patients' personal goals for community-based participation.
Liew, S.-L., Thompson, T., Ramirez, J., Butcher, P., Taylor, J. A., & Celnik, P. A. (2018). Variable neural contributions to explicit and implicit learning during visuomotor adaptation. Frontiers in Neuroscience, 12, 610. https://doi.org/10.3389/fnins.2018.00610 Show abstract
We routinely make fine motor adjustments to maintain optimal motor performance. These adaptations have been attributed to both implicit, error-based mechanisms, and explicit, strategy-based mechanisms. However, little is known about the neural basis of implicit versus explicit learning. Here, we aimed to use anodal transcranial direct current stimulation (tDCS) to probe the relationship between different brain regions and learning mechanisms during a visuomotor adaptation task in humans. We hypothesized that anodal tDCS over the cerebellum (CB) should increase implicit learning while anodal tDCS over the dorsolateral prefrontal cortex (dlPFC), a region associated with higher-level cognition, should facilitate explicit learning. Using a horizontal visuomotor adaptation task that measures explicit/implicit contributions to learning (Taylor et al., 2014), we found that dlPFC stimulation significantly improved performance compared to the other groups, and weakly increased explicit learning. However, CB stimulation had no effects on either target error or implicit learning. Previous work showed variable CB stimulation effects only on a vertical visuomotor adaptation task (Jalali et al., 2017), so in Experiment 2, we conducted the same study using a vertical context to see if we could find effects of CB stimulation. We found only weak effects of CB stimulation on target error and implicit learning, and now the dlPFC effect did not replicate. To resolve this discrepancy, in Experiment 3, we examined the effect of context (vertical vs. horizontal) on implicit and explicit contributions and found that individuals performed significantly worse and used greater implicit learning in the vertical screen condition compared to the horizontal screen condition. Across all experiments, however, there was high inter-individual variability, with strong influences of a few individuals, suggesting that these effects are not consistent across individuals. Overall, this work provides preliminary support for the idea that different neural regions can be engaged to improve visuomotor adaptation, but shows that each region’s effects are highly context-dependent and not clearly dissociable from one another. This holds implications especially in neurorehabilitation, where an intact neural region could be engaged to potentially compensate if another region is impaired. Future work should examine factors influencing interindividual variability during these processes.

Research on autism spectrum disorder (ASD) and on Alzheimer's Disease (AD) and other types of dementia describes a behaviour called 'wandering', a term that denotes movement through space lacking intention or exact destination, as when a person is disoriented or not self-aware. In the U.S., 'wandering' in both ASD and AD has been examined mostly from a management and prevention perspective. It prioritizes safety while primarily overlooking personal experiences of those who 'wander' and their families, thus limiting the range of potentially effective strategies to address this issue. Communicative challenges faced by many people diagnosed with ASD and AD further obscure the experiential, existential aspects of 'wandering'. This article reflects an increasing concern of social science scholars interested in whether and how the conceptual and practical strategies to address 'wandering' are informed by the situated experiences of people with cognitive and developmental disabilities and their families. We examine 'wandering' at the intersections of personal experience, family life, clinical practice, public health policy, and legislation, as a conceptually rich site where notions of personhood, subjectivity, intentionality, and quality of life powerfully and consequentially converge to impact the lives of many people with ASD and AD, and their families. We draw upon critical autism studies describing how attributions of personhood, subjectivity, intentionality, rational agency, and moral autonomy of people with ASD have been contingent upon the norms and conventions governing movement of the human body through space (Hilton, Afr Am Rev 50(2):221-235, 2017). When this movement is deemed aberrant, the person may be construed as irrational, a danger to self because of a lack of self-awareness, and a danger to others because of a lack of empathy. These attributions put the person at risk of being excluded from the considerations and, more importantly, the obligations of the 'moral community' to ensure that he or she has a 'good human life' (Barnbaum, The Ethics of Autism: Among Them but not of Them. Indiana University Press, Bloomington, 2008; Silvers and Francis, Metaphilosophy 40(3/4):475-498, 2009). Using ethnographic, narrative phenomenological (Mattingly, The Paradox of Hope: Journeys through a Clinical Borderland. Berkeley: University of California Press, 2010), and medical humanities (Charon, JAMA 286:1897-1902, 2001; Narrative Medicine: Honoring the Stories of Illness. New York: Oxford University Press, 2006) approaches, we examine multiple perspectives on 'wandering' in ASD and AD across narrative discourse genres, institutional contexts, and media of representation. We argue for an extension of the prevention and management view to focus not only on safety but also on what phenomenologist Merleau-Ponty (1962) called "having a world" (p. 146). The analysis is intended to inform clinical practice, policy and public health efforts to enhance understanding of first and second person perspectives on 'wandering' in order to improve the participation and quality of life of people with ASD and AD who 'wander', and their families.
Ito, K. L., Kumar, A., Zavaliangos-Petropulu, A., Cramer, S. C., & Liew, S.-L. (2018). Pipeline for Analyzing Lesions After Stroke (PALS). Frontiers in Neuroinformatics, 12, 63. https://doi.org/10.3389/fninf.2018.00063 Show abstract
Lesion analyses are critical for drawing insights about stroke injury and recovery, and their importance is underscored by growing efforts to collect and combine stroke neuroimaging data across research sites. However, while there are numerous processing pipelines for neuroimaging data in general, few can be smoothly applied to stroke data due to complications analyzing the lesioned region. As researchers often use their own tools or manual methods for stroke MRI analysis, this could lead to greater errors and difficulty replicating findings over time and across sites. Rigorous analysis protocols and quality control pipelines are thus urgently needed for stroke neuroimaging. To this end, we created the Pipeline for Analyzing Lesions after Stroke (PALS; DOI: https://doi.org/10.5281/zenodo.1266980), a scalable and user-friendly toolbox to facilitate and ensure quality in stroke research using T1-weighted MRIs. The PALS toolbox offers four modules integrated into a single pipeline, including (1) reorientation to radiological convention, (2) lesion correction for healthy white matter voxels, (3) lesion load calculation, and (4) visual quality control. In the present paper, we discuss each module and provide validation and example cases of our toolbox using multi-site data. Importantly, we also show that lesion correction with PALS significantly improves similarity between manual lesion segmentations by different tracers (z=3.43, p=0.0018). PALS can be found online at https://github.com/npnl/PALS. Future work will expand the PALS capabilities to include multimodal stroke imaging. We hope PALS will be a useful tool for the stroke neuroimaging community and foster new clinical insights.

A preliminary comparison of motor learning across different non-invasive brain stimulation paradigms shows no consistent modulations. Frontiers in Neuroscience, 12, 253. https://doi.org/10.3389/fnins.2018.00253 Show abstract
Non-invasive brain stimulation (NIBS) has been widely explored as a way to safely modulate brain activity and alter human performance for nearly three decades. Research using NIBS has grown exponentially within the last decade with promising results across a variety of clinical and healthy populations. However, recent work has shown high inter-individual variability and a lack of reproducibility of previous results. Here, we conducted a small preliminary study to explore the effects of three of the most commonly used excitatory NIBS paradigms over the primary motor cortex (M1) on motor learning (Sequential Visuomotor Isometric Pinch Force Tracking Task) and secondarily relate changes in motor learning to changes in cortical excitability (MEP amplitude and SICI). We compared anodal transcranial direct current stimulation (tDCS), paired associative stimulation (PAS25), and intermittent theta burst stimulation (iTBS), along with a sham tDCS control condition. Stimulation was applied prior to motor learning. Participants (n = 28) were randomized into one of the four groups and were trained on a skilled motor task. Motor learning was measured immediately after training (online), 1 day after training (consolidation), and 1 week after training (retention). We did not find consistent differential effects on motor learning or cortical excitability across groups. Within the boundaries of our small sample sizes, we then assessed effect sizes across the NIBS groups that could help power future studies. These results, which require replication with larger samples, are consistent with previous reports of small and variable effect sizes of these interventions on motor learning.

Introduction. Occupational scientists are tasked with the responsibility of examining the relationship between occupational engagement and health, yet as occupations are explored in situ, these concepts only become more complex. For example, lifestyle trade-offs occur when individuals make conscious decisions between two competing sets of actions: actions taken in promotion of physical health versus actions in agreement with an identity-driven biography. In this study, these dilemmas are viewed as parts of an ongoing occupational challenge to balance physical health with subjective well-being in everyday life.
Methods. Anselm Strauss’s concepts of body state and biographical moment are conceptualized as analytic tools to study dimensions within which occupation is performed. A descriptive, single-case analysis of a young adult diagnosed with diabetes is presented as an exemplar of how Strauss’s tools may be utilized.
Results. Four themes emerged within the presented narrative: (1) by the book versus reality, (2) testing the boundaries of diabetes, (3) diabetes burnout and the struggle for perfection, and (4) the inevitable merge between body and biography.
Conclusion. Sadie’s narrative exemplifies the multiple contexts in which agentic decisions to engage in specific occupations are made. Sadie’s experiences of diabetes burnout and actions taken while “on vacation” are not uncommon within chronic illness literature and warrant further analyses that consider physical and psychological domains of health. By dismantling situational factors using analytic tools, such as Strauss’s body state and biographical moment, occupational scientists may further understand lived experiences and clarify the link between occupation and health.

Aims. To identify rehabilitation providers' perspectives on barriers and facilitators of patient engagement in hip fracture patients in skilled nursing facilities (SNFs) within the social ecological model.
Methods. We conducted 13 focus groups in SNFs throughout Los Angeles County comprised of rehabilitation staff (n = 99). Focus groups were audio-recorded and transcribed. A secondary analysis of themes related to patient engagement were identified and organized within the social ecological model.
Results. Clinicians identified barriers and facilitators of patient engagement across all levels of the social ecological model: public policy (e.g., insurance), organizational (e.g., facility culture), interpersonal (e.g., clinicians fostering self-reflection), and intrapersonal (e.g., patients' anxiety).
Conclusions. Examining barriers and facilitators to patient engagement has highlighted areas which need to be sustained and improved. Thus, these findings will inform future efforts to enhance patient engagement in order can to optimize patient healthcare decisions.

The transactional perspective informed by John Dewey’s philosophy continues to mature in occupational science. Scholars have called for more attention to the community orientation within a transactional perspective, necessitating deeper engagement with Dewey’s political writings. As a contribution to that effort, this article outlines Dewey’s political philosophy and connects his notions of occupation and associated living with his broader ideas about freedom, equality, growth, and justice. Dewey’s enduring attention to democracy throughout his career established a particular function for occupation vis-à-vis the intentionally constructed social relations that constitute associated living. Culminating in his vision of a Great Community, Dewey’s focus on the conditions of associated living provides compelling directions for thinking about and pursuing occupational justice.

Ensuring that older adults are receiving quality and effective rehabilitation and skilled nursing services must be a priority to society and to the health care system, but health care policies and systems driving reimbursement continue to challenge the delivery of services. A review of the literature indicates significant problems among residents of skilled nursing facilities (SNFs) that could be alleviated by meaningful occupational therapy. Research and practice in the occupational therapy community should focus on this large area of practice. Advocacy by individual practitioners—challenging themselves and others to provide more patient-centered care—can lead to changes that benefit clients, facilities, and payment systems as well as contribute to career satisfaction of occupational therapy practitioners. Occupational therapy can and should serve as catalyst for culture change in SNFs by providing meaningful interventions and opportunities that support engagement and health.

More than 100 people have graduated with occupational science doctoral degrees in North America. Accordingly, there is a body of work that can be examined to assess what qualities have characterized doctoral-level occupational science inquiry to-date. In this preliminary study, we performed a directed content analysis of 101 dissertation abstracts published between 1994 and 2015 from four occupational science doctoral programs in the United States and Canada. Our analysis explored the extent to which the 101 doctoral studies, as evidenced by their abstracts, directly contributed to knowledge of occupation or humans as occupational beings. Our findings suggested that 40 studies made a direct contribution, 29 made an indirect contribution, and 32 made no contribution to the study of occupation or humans as occupational beings. Additional analyses revealed that studies in the direct and indirect categories relied heavily (80% and 69%, respectively) on qualitative methodologies, whereas studies in the no contribution category were more evenly split across qualitative (37%) and quantitative (47%) methodologies. A variety of topics and themes characterized studies in each category, and further research on 92 doctoral students’ post-graduation publications showed that 50 made contributions to occupational science’s knowledge base through published articles or book chapters. The findings from this preliminary inquiry provide a basis to critically reflect on the goals, outcomes, and functions of occupational science doctoral education as well as how the discipline has developed through doctoral work within evolving academic, scientific, and political landscapes.

We examined how demographic and clinical characteristics differ between emergency department (ED) visits for epilepsy (EP cohort) and ED visits for other reasons (non-EP cohort) in children with ASD. The data were drawn from the 2009 and 2010 Nationwide Emergency Department Sample. We performed both univariate and multivariate analyses to compare and contrast similarities and differences between EP cohort and non-EP cohort among children with ASD. The results showed ED visits in EP cohort were more likely to occur among adolescents aged 13–17 years, less likely to occur among children with co-occurring psychiatric conditions, and were more likely to co-occur with injury. We discussed some unique challenges for managing children with both ASD and epilepsy.

Laterality of poststroke cortical motor activity during action observation is related to hemispheric dominance. Neural Plasticity, 2018, 3524960. https://doi.org/10.1155/2018/3524960 Show abstract
Background. Increased activity in the lesioned hemisphere has been related to improved poststroke motor recovery. However, the role of the dominant hemisphere—and its relationship to activity in the lesioned hemisphere—has not been widely explored.
Objective. Here, we examined whether the dominant hemisphere drives the lateralization of brain activity after stroke and whether this changes based on if the lesioned hemisphere is the dominant hemisphere or not.
Methods. We used fMRI to compare cortical motor activity in the action observation network (AON), motor-related regions that are active both during the observation and execution of an action, in 36 left hemisphere dominant individuals. Twelve individuals had nondominant, right hemisphere stroke, twelve had dominant, left-hemisphere stroke, and twelve were healthy age-matched controls. We previously found that individuals with left dominant stroke show greater ipsilesional activity during action observation. Here, we examined if individuals with nondominant, right hemisphere stroke also showed greater lateralized activity in the ipsilesional, right hemisphere or in the dominant, left hemisphere and compared these results with those of individuals with dominant, left hemisphere stroke.
Results. We found that individuals with right hemisphere stroke showed greater activity in the dominant, left hemisphere, rather than the ipsilesional, right hemisphere. This left-lateralized pattern matched that of individuals with left, dominant hemisphere stroke, and both stroke groups differed from the age-matched control group.
Conclusions. These findings suggest that action observation is lateralized to the dominant, rather than ipsilesional, hemisphere, which may reflect an interaction between the lesioned hemisphere and the dominant hemisphere in driving lateralization of brain activity after stroke. Hemispheric dominance and laterality should be carefully considered when characterizing poststroke neural activity.

Over the past decade many studies indicate that we utilize our own motor system to understand the actions of other people. This mirror neuron system (MNS) has been proposed to be involved in social cognition and motor learning. However, conflicting findings regarding the underlying mechanisms that drive these shared circuits make it difficult to decipher a common model of their function. Here we propose adapting a “value-driven” model to explain discrepancies in the human mirror system literature and to incorporate this model with existing models. We will use this model to explain discrepant activation patterns in multiple shared circuits in the human data, such that a unified model may explain reported activation patterns from previous studies as a function of value.

Prediction of activation patterns preceding hallucinations in patients with schizophrenia using machine learning with structured sparsity. Human Brain Mapping, 39(4), 1777-1788. https://doi.org/10.1002/hbm.23953 Show abstract
Despite significant progress in the field, the detection of fMRI signal changes during hallucinatory events remains difficult and time‐consuming. This article first proposes a machine‐learning algorithm to automatically identify resting‐state fMRI periods that precede hallucinations versus periods that do not. When applied to whole‐brain fMRI data, state‐of‐the‐art classification methods, such as support vector machines (SVM), yield dense solutions that are difficult to interpret. We proposed to extend the existing sparse classification methods by taking the spatial structure of brain images into account with structured sparsity using the total variation penalty. Based on this approach, we obtained reliable classifying performances associated with interpretable predictive patterns, composed of two clearly identifiable clusters in speech‐related brain regions. The variation in transition‐to‐hallucination functional patterns not only from one patient to another but also from one occurrence to the next (e.g., also depending on the sensory modalities involved) appeared to be the major difficulty when developing effective classifiers. Consequently, second, this article aimed to characterize the variability within the prehallucination patterns using an extension of principal component analysis with spatial constraints. The principal components (PCs) and the associated basis patterns shed light on the intrinsic structures of the variability present in the dataset. Such results are promising in the scope of innovative fMRI‐guided therapy for drug‐resistant hallucinations, such as fMRI‐based neurofeedback.

Occupational therapy intervention improves glycemic control and quality of life among young adults with diabetes: The Resilient, Empowered, Active Living With Diabetes (REAL Diabetes) randomized controlled trial. Diabetes Care, 41(4), 696-704. https://doi.org/10.2337/dc17-1634 Show abstract
Objective. To assess the efficacy of a manualized occupational therapy (OT) intervention (Resilient, Empowered, Active Living with Diabetes [REAL Diabetes]) to improve glycemic control and psychosocial well-being among ethnically diverse young adults with low socioeconomic status (SES) who have type 1 or type 2 diabetes.
Research Design and Methods. Eighty-one young adults (age 22.6 ± 3.5 years; hemoglobin A1c [HbA1c] = 10.8%/95 mmol/mol ± 1.9%/20.8 mmol/mol) were randomly assigned to the REAL Diabetes intervention group (IG) or an attention control group (CG) over 6 months. IG participants received biweekly sessions guided by a manual composed of seven content modules; CG participants received standardized educational materials and biweekly phone calls. Blinded assessors collected data at baseline and 6 months. The primary outcome was HbA1c; secondary outcomes included diabetes self-care, diabetes-related quality of life (QOL), diabetes distress, depressive symptoms, and life satisfaction. Change scores were analyzed using Wilcoxon rank sum tests.
Results. Intent-to-treat analyses showed that IG participants showed significant improvement in HbA1c (-0.57%/6.2 mmol/mol vs. +0.36%/3.9 mmol/mol, P = 0.01), diabetes-related QOL (+0.7 vs. +0.15, P = 0.04), and habit strength for checking blood glucose (+3.9 vs. +1.7, P = 0.05) as compared with CG participants. There was no statistically significant effect modification by sex, ethnicity, diabetes type, recruitment site, or SES. No study-related serious adverse events were reported.
Conclusions. The REAL Diabetes intervention improved blood glucose control and diabetes-related QOL among a typically hard-to-reach population, thus providing evidence that a structured OT intervention may be beneficial in improving both clinical and psychosocial outcomes among individuals with diabetes.

Assessing quality of program environments for children and youth with autism: Autism Program Environment Rating Scale (APERS). Journal of Autism and Developmental Disorders, 48(3), 913–924. https://doi.org/10.1007/s10803-017-3379-7 Show abstract
The purpose of this study was to examine the psychometric properties of the Autism Program Environment Rating Scale (APERS), an instrument designed to assess quality of program environments for students with autism spectrum disorder. Data sets from two samples of public school programs that provided services to children and youth with autism spectrum disorder were utilized. Cronbach alpha analyses indicated high coefficients of internal consistency for the total APERS and moderate levels for item domains for the first data set, which was replicated with the second data set. A factor analysis of the first data set indicated that all domain scores loaded on one main factor, in alignment with the conceptual model, with this finding being replicated in the second data set. Also, the APERS was sensitive to changes resulting from a professional development program designed to promote program quality.

Journal of Autism and Developmental Disorders, 48(3), 853–867. https://doi.org/10.1007/s10803-017-3386-8 Show abstract
A randomized controlled trial was conducted to evaluate effects of the Joint Attention Mediated Learning (JAML) intervention. Toddlers with autism spectrum disorders (ASD) aged 16–30 months (n = 144) were randomized to intervention and community control conditions. Parents, who participated in 32 weekly home-based sessions, followed a mediated learning process to target preverbal social communication outcomes (social visual synchrony, reciprocity, and responding and initiating forms of joint attention) throughout daily interactions. The analysis found post-intervention effects for all outcomes, with all except initiating joint attention sustaining 6 months post-intervention. Findings support the value of very early intervention targeting explicitly social functions of preverbal communication and of promoting active engagement in the learning process for both toddlers and parents.

Diabetes Empowerment Council: Integrative Pilot Intervention for Transitioning Young Adults With Type 1 Diabetes. Global Advances in Health and Medicine. Advance online publication. https://doi.org/10.1177/2164956118761808 Show abstract
Background. The transition of young adults with type 1 diabetes (T1D) from pediatric to adult care is challenging and frequently accompanied by worsening of diabetes-related health. To date, there are no reports which prospectively assess the effects of theory-based psycho-behavioral interventions during the transition period neither on glycemic control nor on psychosocial factors that contribute to poor glycemic control. Therefore, the overall aim of this study was to develop and pilot test an integrative group intervention based on the underlying principles of self-determination theory (SDT), in young adults with T1D.
Methods. Fifty-one young adults with T1D participated in an education and case management-based transition program, of which 9 took part in the Diabetes Empowerment Council (DEC), a 12-week holistic, multimodality facilitated group intervention consisting of “council” process based on indigenous community practices, stress-reduction guided imagery, narrative medicine modalities, simple ritual, and other integrative modalities. Feasibility, acceptability, potential mechanism of effects, and bio-behavioral outcomes were determined using mixed qualitative and quantitative methods.
Results. The intervention was highly acceptable to participants, though presented significant feasibility challenges. Participants in DEC showed significant reductions in perceived stress and depression, and increases in general well-being relative to other control participants. Reduction in perceived stress, independent of intervention group, was associated with reductions in hemoglobin A1C. A theoretical model explaining the effects of the intervention included the promotion of relatedness and autonomy support, 2 important aspects of SDT.
Conclusions. The DEC is a promising group intervention for young adults with T1D going through transition to adult care. Future investigations will be necessary to resolve feasibility issues, optimize the multimodality intervention, determine full intervention effects, and fully test the role of the underlying theoretical model of action.

Purpose of the Study. This study investigated the mechanisms of change underlying an activity-based lifestyle intervention, an occupational therapy program aimed at promoting healthy habits, and routines in older adults. We examined two activity-relevant factors as potential mediators linking the intervention to reduced symptoms of depression: activity frequency and global perceptions of activity significance. Social connections and perceived control were assessed to understand how activity-related factors relate to reduced symptoms of depression.
Design and Methods. The sample consisted of 460 multiethnic community-dwelling older adults aged 60-95 years. Participants were randomly assigned to a 6-month lifestyle redesign intervention (n = 232) or a no-treatment control (n = 228) condition. After the 6-month period, 360 individuals completed post-testing. Latent change score models were used to represent changes from baseline over the experimental interval. Structural equation models were applied to examine the indirect effects of the intervention on reduced depressive symptoms.
Results. The results demonstrated significant indirect effects from intervention receipt to decreased depressive symptoms via increased activity frequency and activity significance. Higher activity frequency was linked to fewer depressive symptoms via heightened social connections, whereas increased activity significance was associated with fewer depressive symptoms via enhanced perceived control.
Implications. The results support basic principles of occupational therapy by highlighting important mediating roles of activity frequency and activity significance in reducing depressive symptoms. Understanding of these change mechanisms can help optimize activity-centered interventions to reduce depressive symptoms.

A large, open source dataset of stroke anatomical brain images and manual lesion segmentations. Scientific Data, 5, 180011. https://doi.org/10.1038/sdata.2018.11 Show abstract
Stroke is the leading cause of adult disability worldwide, with up to two-thirds of individuals experiencing long-term disabilities. Large-scale neuroimaging studies have shown promise in identifying robust biomarkers (e.g., measures of brain structure) of long-term stroke recovery following rehabilitation. However, analyzing large rehabilitation-related datasets is problematic due to barriers in accurate stroke lesion segmentation. Manually-traced lesions are currently the gold standard for lesion segmentation on T1-weighted MRIs, but are labor intensive and require anatomical expertise. While algorithms have been developed to automate this process, the results often lack accuracy. Newer algorithms that employ machine-learning techniques are promising, yet these require large training datasets to optimize performance. Here we present ATLAS (Anatomical Tracings of Lesions After Stroke), an open-source dataset of 304 T1-weighted MRIs with manually segmented lesions and metadata. This large, diverse dataset can be used to train and test lesion segmentation algorithms and provides a standardized dataset for comparing the performance of different segmentation methods. We hope ATLAS release 1.1 will be a useful resource to assess and improve the accuracy of current lesion segmentation methods.

Adolescents with autism spectrum disorder have limited participation in the transition planning process, despite the link between active participation and an improvement in postsecondary education and employment outcomes. The Secondary School Success Checklist was designed to support transition planning for adolescents with autism spectrum disorder by incorporating their own assessments of strengths, skill deficits, and prioritization for instruction along with those of their parents and teachers across multiple skill domains. Findings from more than 500 adolescents with autism spectrum disorder across the United States indicate discrepancies between adolescent, teacher, and parent ratings of skills highlighting the importance of the inclusion of multiple perspectives in transition planning. Although ratings varied, agreement between adolescents with autism spectrum disorder, parents, and teachers across the highest and lowest rated skills suggests the need to broaden the focus on critical transition skills to include problem-solving, planning for life after high school, and self-advocacy.

An occupational perspective is relevant in examining how the unique context of a person’s life and environment can impact the types of occupations in which he or she participates, and the dilemmas that can occur when restrictive surroundings or perceived lack of lifestyle options constrain occupational choices. This paper examines how participation in gangs by Latino adolescent males may be due to the limited options for other occupations that low socioeconomic status (SES) neighborhoods afford. By presenting narrative from the memoir of a former gang member, alongside county public health records, the engaging and health-promoting occupations as well as health-threatening occupations of gang life are explored. This scholarly discussion contributes to occupational science by evaluating the relationship between context and occupational possibilities for Latino male adolescents living in constrained environments.

Few studies have compared atypical sensory characteristics and food selectivity between children with and without autism spectrum disorder (ASD). We compared oral sensory processing between children with (n = 53) and without ASD (n = 58), ages 3–11 years. We also examined the relationships between atypical oral sensory processing, food selectivity, and fruit/vegetable consumption in children with ASD. We found that more children with ASD presented with atypical sensory processing than children without ASD. Among children with ASD, those with atypical oral sensory sensitivity refused more foods and ate fewer vegetables than those with typical oral sensory sensitivity. The findings suggest that efforts to address food selectivity in children with ASD may be enhanced by including strategies that address oral sensory processing.

Children with short bowel syndrome (SBS) with associated intestinal failure may be unable to absorb sufficient nutrients to sustain life. Improvements in the medical management of SBS, including use of parenteral nutrition, has significantly increased life expectancy. Independence from parenteral nutrition further improves quality of life. However, children living with SBS often develop oral aversions and feeding difficulties. There is limited research and information on which to base interventions that will preserve and develop oral motor and feeding skills. The aims of this article are to explore what is known about children with SBS who exhibit oral aversion/feeding difficulties and to suggest research for possible future interventions that could help these children overcome oral aversion, eat orally, and increase participation and satisfaction in mealtimes. This review explores the complexity of feeding children with SBS. Three underlying themes emerged: physical, developmental, and social aspects of eating and mealtimes. Interdisciplinary teams are needed to effectively address these complex oral feeding problems. Accurate identification the underlying issues will allow healthcare providers to develop interventions to improve feeding outcomes for children with SBS. Future research should focus on evaluating the effectiveness of interventions that address each of the underlying issues.

This systematic review examined the effectiveness of specific sensory techniques and sensory environmental modifications to improve participation of children with sensory integration (SI) difficulties. Abstracts of 11,436 articles published between January 2007 and May 2015 were examined. Studies were included if designs reflected high levels of evidence, participants demonstrated SI difficulties, and outcome measures addressed function or participation. Eight studies met inclusion criteria. Seven studies evaluated effects of specific sensory techniques for children with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder: Qigong massage, weighted vests, slow swinging, and incorporation of multisensory activities into preschool routines. One study of sensory environmental modifications examined adaptations to a dental clinic for children with ASD. Strong evidence supported Qigong massage, moderate evidence supported sensory modifications to the dental care environment, and limited evidence supported weighted vests. The evidence is insufficient to draw conclusions regarding slow linear swinging and incorporation of multisensory activities into preschool settings.

Involuntary force variability below 15 Hz arises from, and is influenced by, many factors including descending neural drive, proprioceptive feedback, and mechanical properties of muscles and tendons. However, their potential interactions that give rise to the well-structured spectrum of involuntary force variability are not well understood due to a lack of experimental techniques. Here, we investigated the generation, modulation, and interactions among different sources of force variability using a physiologically-grounded closed-loop simulation of an afferented muscle model. The closed-loop simulation included a musculotendon model, muscle spindle, Golgi tendon organ (GTO), and a tracking controller which enabled target-guided force tracking. We demonstrate that closed-loop control of an afferented musculotendon suffices to replicate and explain surprisingly many cardinal features of involuntary force variability. Specifically, we present 1) a potential origin of low-frequency force variability associated with co-modulation of motor unit firing rates (i.e.,‘common drive’), 2) an in-depth characterization of how proprioceptive feedback pathways suffice to generate 5-12 Hz physiological tremor, and 3) evidence that modulation of those feedback pathways (i.e., presynaptic inhibition of Ia and Ib afferents, and spindle sensitivity via fusimotor drive) influence the full spectrum of force variability. These results highlight the previously underestimated importance of closed-loop neuromechanical interactions in explaining involuntary force variability during voluntary ‘isometric’ force control. Furthermore, these results provide the basis for a unifying theory that relates spinal circuitry to various manifestations of altered involuntary force variability in fatigue, aging and neurological disease.

Cascading effects of attention disengagement and sensory seeking on social symptoms in a community sample of infants at-risk for a future diagnosis of autism spectrum disorder. Developmental Cognitive Neuroscience, 29, 30-40. https://doi.org/10.1016/j.dcn.2017.08.006 Show abstract
Recent work suggests sensory seeking predicts later social symptomatology through reduced social orienting in infants who are at high-risk for autism spectrum disorder (ASD) based on their status as younger siblings of children diagnosed with ASD. We drew on extant longitudinal data from a community sample of at-risk infants who were identified at 12 months using the First Year Inventory, and followed to 3–5 years. We replicate findings of Damiano et al. (in this issue) that a) high-risk infants who go on to be diagnosed with ASD show heightened sensory seeking in the second year of life relative to those who do not receive a diagnosis, and b) increased sensory seeking indirectly relates to later social symptomatology via reduced social orienting. We extend previous findings to show that sensory seeking has more clinical utility later in the second year of life (20–24 months) than earlier (13–15 months). Further, this study suggests that diminished attention disengagement at 12–15 months may precede and predict increased sensory seeking at 20–24 months. Findings add support for the notion that sensory features produce cascading effects on social development in infants at risk for ASD, and suggest that reduced attention disengagement early in life may set off this cascade.

Many children and youth with and without disabilities are affected by challenges in processing and integrating sensations. Occupational therapy practitioners serve a pivotal role in the evaluation and treatment of this population. This special section of the American Journal of Occupational Therapy includes articles that elucidate the relationship between sensory processing and participation in valued occupations as well as articles that guide best practice, including systematic reviews on common occupational therapy interventions for children and youth with challenges in processing and integrating sensation. This editorial elaborates on key issues for future research.

Despite the importance of sexuality to overall quality of life and well-being for individuals with disabilities, occupational therapy practitioners continue to under-address this issue. One possibility for the lack of attention in this area is the comfort and knowledge level of practitioners. In their seminal work, Payne, Greer, and Corbin (1988) surveyed occupational therapy programs in the United States in an effort to identify the amount of sexuality education provided. This study was aimed at identifying current trends in the provision of sexuality education for occupational therapy students. Despite the nearly 30-year gap in this area of research, and the societal changes related to sexuality, findings suggest that there has been little advancement in the area of sexuality in occupational therapy curricula. Implications for occupational therapy practice and future education are discussed.

Background: Perspectives that individualize occupation are poorly aligned with socially responsive and transformative occupation-focused research, education, and practice. Their predominant use in occupational therapy risks the perpetuation, rather than resolution, of occupational inequities.
Aim: In this paper, we problematize taken-for-granted individualistic analyses of occupation and illustrate how critical theoretical perspectives can reveal the ways in which structural factors beyond an individual’s immediate control and environment shape occupational possibilities and occupational engagement.
Method: Using a critically reflexive approach, we draw on three distinct qualitative research studies to examine the potential of critical theorizing for expanding beyond a reliance on individualistic analyses and practices.
Results: Our studies highlight the importance of addressing the socio-historical and political contexts of occupation and demonstrate the contribution of critical perspectives to socially responsive occupational therapy.
Conclusion and significance: In expanding beyond individualistic analyses of occupation, critical perspectives advance research and practices towards addressing socio-political mediators of occupational engagement and equity.

Objective. We investigated the feasibility and acceptability of an occupational therapy intervention targeting diabetes management for underserved young adults.
Method. Eight participants completed the intervention and a battery of assessments at baseline and after the intervention. At completion, the participants and occupational therapist were interviewed about their experiences with the study. Four categories of assessment questions were used to guide the study: process, resource, management, and scientific.
Results. Successes included recruitment; fulfillment of tasks by staff and partnering clinics; adequate space, financial support, and equipment; and meaningfulness of the intervention for participants. Challenges included scheduling participants for the intervention and follow-up focus groups and providing client centeredness and flexibility while reducing burden on the intervener.
Conclusion. This feasibility study allowed us to make necessary revisions to our study protocol before implementing a larger pilot study.

Physiological tremor increases when skeletal muscle is shortened: implications for fusimotor control. The Journal of Physiology, 595(24), 7331-7346. https://doi.org/10.1113/JP274899 Show abstract
The involuntary force fluctuations associated with physiological (as distinct from pathological) tremor are an unavoidable component of human motor control. While the origins of physiological tremor are known to depend on muscle afferentation, it is possible that the mechanical properties of muscle–tendon systems also affect its generation, amplification and maintenance. In this paper, we investigated the dependence of physiological tremor on muscle length in healthy individuals. We measured physiological tremor during tonic, isometric plantarflexion torque at 30% of maximum at three ankle angles. The amplitude of physiological tremor increased as calf muscles shortened in contrast to the stretch reflex whose amplitude decreases as muscle shortens. We used a published closed‐loop simulation model of afferented muscle to explore the mechanisms responsible for this behaviour. We demonstrate that changing muscle lengths does not suffice to explain our experimental findings. Rather, the model consistently required the modulation of γ‐static fusimotor drive to produce increases in physiological tremor with muscle shortening – while successfully replicating the concomitant reduction in stretch reflex amplitude. This need to control γ‐static fusimotor drive explicitly as a function of muscle length has important implications. First, it permits the amplitudes of physiological tremor and stretch reflex to be decoupled. Second, it postulates neuromechanical interactions that require length‐dependent γ drive modulation to be independent from α drive to the parent muscle. Lastly, it suggests that physiological tremor can be used as a simple, non‐invasive measure of the afferent mechanisms underlying healthy motor function, and their disruption in neurological conditions.
Wu, A. H., Vigen, C. L., Butler, L. M., & Tseng, C.-C. (2017). Metabolic conditions and breast cancer risk among Los Angeles County Filipina Americans compared with Chinese and Japanese Americans. International Journal of Cancer, 141(12), 2450-2461. https://doi.org/10.1002/ijc.31018 Show abstract
Accumulating evidence suggests that the aggregation of common metabolic conditions (high blood pressure, diabetes and dyslipidemia) is a risk factor for breast cancer. Breast cancer incidence has risen steadily in Asian American women, and whether these metabolic conditions contribute to breast cancer risk in certain Asian American subgroups is unknown. We investigated the role of physician-diagnosed hypertension, high cholesterol and diabetes separately, and in combination, in relation to the risk of breast cancer in a population-based case–control study of 2,167 Asian Americans diagnosed with breast cancer and 2,035 age and ethnicity matched control women in Los Angeles County. Compared to Asian American women who did not have any of the metabolic conditions, those with 1, 2 or 3 conditions showed a steady increase in risk (respective odds ratios were 1.12, 1.42 and 1.62; P trend = 0.001) with adjustment for covariates including body mass index. Similar significant trends were observed in Filipina Americans (P trend = 0.021), postmenopausal women (P trend =0.001), Asian women who were born in the United States (US) (P trend = 0.052) and migrants who have lived in the US for at least 20 years (P trend = 0.004), but not migrants who lived in the US for <20 years (P trend = 0.64). These results suggest that westernization in lifestyle (diet and physical inactivity) and corresponding increase in adiposity have contributed to the rising prevalence of these metabolic conditions, which in turn, are associated with an increase in breast cancer.

Parent-mediated intervention for one-year-olds screened as at-risk for autism spectrum disorder: A randomized controlled trial. Journal of Autism and Developmental Disorders, 47(11), 3520-3540. https://doi.org/10.1007/s10803-017-3268-0 Show abstract
Theoretically, interventions initiated with at-risk infants prior to the point in time a definitive autism spectrum disorder (ASD) diagnosis can be made will improve outcomes. Pursuing this idea, we tested the efficacy of a parent-mediated early intervention called Adapted Responsive Teaching (ART) via a randomized controlled trial with 87 one-year-olds identified by community screening with the First Year Inventory as at-risk of later ASD diagnoses. We found minimal evidence for main effects of ART on child outcomes. However, ART group parents showed significantly greater increases in responsiveness to their infants than control group parents. Further, significant indirect (mediation) effects of assignment group on multiple child outcomes through changes in parent responsiveness supported our theory of change.

A pilot study to precisely quantify forces applied by sonographers while scanning: A step toward reducing ergonomic injury. Work, 58(2), 241-247. https://doi.org/10.3233/WOR-172611 Show abstract
There is a significantly high rate of work-related musculsokeletal injuries in sonography professionals. To date, assessment of risk factors for work- related injuries in sonographers has been based primarily on surveys, subjective reports, and observational methods. There is a need to develop quantitative techniques to better understand risk factors and develop preventive interventions.
Objective. We pilot tested a high-resolution force-measuring probe capable of precisely measuring forces applied through the transducer by sonographers and used this novel direct measurement technique to evaluate forces during abdominal imaging.
Methods. Twelve sonographers with varied experience, ranging from 1-33 years, performed routine abdominal scans on 10 healthy volunteers who had varied body mass indices (BMI). Imaging was conducted using the force-measuring probe, which provided real-time measurement of forces, and angles. Data were compared by sonographer years of experience and subject BMI.
Results. In total, 47 abdominal examinations were performed as part of this study, and all images met standards for clinical diagnostic quality. The mean contact force applied across all exams was 8.2±4.3 Newtons (N) (range: 1.2-36.5 N). For subjects in the high BMI group (BMI>25, n = 4) the mean force was 10.5 N (range: 8.9-13.2 N) compared to 7.9 N (range: 5.9-10.9 N) for subjects with normal BMI (BMI = 18.5-25, n = 6). Similarly, the mean maximum force applied for subjects with high BMI (25.3 N) was significantly higher than force applied for subjects with normal BMI (17.4 N). No significant difference was noted in the amount of force applied by sonographers with more than 5 years of experience (n = 6) at 8.2 N (Range: 5.1-10.0 N) compared to less experienced sonographers (n = 6), whose forces averaged 8.1 N (Range: 5.8-10.0 N).
Conclusions. It is feasible to directly measure forces applied by sonographers using a high-resolution force measurement system. Forces applied during abdominal imaging vary widely, are significantly higher when scanning subjects with high BMI, and are not related to sonographer years of experience. This force measurement system has the potential to provide an additional quantitative data point to explore the impact of applied forces on sonographer related musculoskeletal injury, particularly in conjunction with various body positions, exam types and force durations.

Our purpose was to validate a reliable method to capture brain activity concomitant with hallucinatory events, which constitute frequent and disabling experiences in schizophrenia. Capturing hallucinations using functional magnetic resonance imaging (fMRI) remains very challenging. We previously developed a method based on a two‐steps strategy including (1) multivariate data‐driven analysis of per‐hallucinatory fMRI recording and (2) selection of the components of interest based on a post‐fMRI interview. However, two tests still need to be conducted to rule out critical pitfalls of conventional fMRI capture methods before this two‐steps strategy can be adopted in hallucination research: replication of these findings on an independent sample and assessment of the reliability of the hallucination‐related patterns at the subject level. To do so, we recruited a sample of 45 schizophrenia patients suffering from frequent hallucinations, 20 schizophrenia patients without hallucinations and 20 matched healthy volunteers; all participants underwent four different experiments. The main findings are (1) high accuracy in reporting unexpected sensory stimuli in an MRI setting; (2) good detection concordance between hypothesis‐driven and data‐driven analysis methods (as used in the two‐steps strategy) when controlled unexpected sensory stimuli are presented; (3) good agreement of the two‐steps method with the online button‐press approach to capture hallucinatory events; (4) high spatial consistency of hallucinatory‐related networks detected using the two‐steps method on two independent samples. By validating the two‐steps method, we advance toward the possible transfer of such technology to new image‐based therapies for hallucinations.

Calls to ‘transcend the individual’ in occupational science have emerged in recognition of the boundaries of individualistic perspectives and the drive to develop a socially responsive science. In this article, we contend that transcending the individual does not equate to neglecting how individuals make sense of and experience occupation; rather, it requires looking at individual constructions of experiences and occupations in critically informed ways that highlight the socio-political influences on those constructions. This discussion article considers how critical narrative inquiry can be taken up as a methodological approach to interpretively link individual ‘stories’ with social ‘stories’ or discourses, enabling further understanding of occupation as a situated and transactional phenomenon. Drawing on data from a study that is attending to transactions of policy, service, and individual perspectives of long-term unemployment, we illustrate how a critical approach to narrative interpretation highlights boundaries, resistance, contradictions, and tensions that provide insights into the situated nature of occupation.

Objective. In this review, we focus on nonmedication treatment approaches to chronic daily headaches and chronic migraine. We review the current scientific data on studies using multimodal treatments, especially physical therapy and occupational therapy, and provide recommendations on the formation of interdisciplinary headache teams.
Background. Chronic daily headache, which includes chronic migraine, is a particularly challenging clinical entity which often involves multiple headache types and comorbidities. A team approach in treating these patients may be particularly useful.
Design/Methods. We review all current studies performed with at least one or more other modality in addition to usual medical treatment, with a focus on physical and occupational therapy. Emphasis on physical and occupational therapy with an explanation of their methods and role in multidisciplinary treatment is a pivotal part of this review. We also suggest approaches to setting up a multimodality clinic for the busy headache clinician.
Conclusion. Setting up a collaborative, multidisciplinary team of specialists in headache practices with the goal of modifying physical, environmental, and psychological triggers for chronic daily headaches may facilitate treatment of these refractory patients.

Madsen and Josephsson’s rich account of ideas from John Dewey’s philosophical writings urges occupational scientists to understand occupation as “something that goes on ... because of a situation, not only by or because of the individual” (p. 12). Although many aspects of their article helpfully re-emphasize important points about pragmatism, occupation, and transformation, their article also suggests issues noted by other Deweyan scholars and omits arguments previously put forth by those working with a Deweyan interpretation of occupation. In this commentary, we offer suggestions for acknowledging and more fully incorporating existing contributions on the topics of occupation, situation, and inquiry. We also highlight potential connections and developments that Madsen and Josephsson’s work may foster in future occupational science scholarship.

American Journal of Health Promotion, 31(5), 388-390. https://doi.org/10.1177/0890117116666947 Show abstract
Purpose. This study used ecological momentary assessment (EMA), a real-time self-report strategy, to examine (1) whether dog owners were more likely to be physically active when they were with their dogs and (2) whether being with a dog amplifies positive and dampens negative affective response during physical activity.
Design. Electronic EMA surveys for 12 days.
Participants. Seventy-one adult dog owners.
Measures. The EMA survey included 1 question about current activity, 3 questions about positive affect (Cronbach α = .837), 4 questions about negative affect (Cronbach α = .865), and 1 question about the presence of dog.
Analysis. Multilevel modeling.
Results. The company of a dog did not increase the likelihood of being active versus sedentary at any given EMA prompt. However, greater positive affect during physical activity was reported in the company of a dog. Negative affect did not differ between active and sedentary activity, regardless of being with a dog or not.
Conclusion. This study demonstrates the utility of electronic EMA as a promising methodology to study dog-accompanied physical activity. Future studies may use EMA to collect further contextual information about dog-accompanied activity to inform the development of innovative physical activity interventions.

Coherence analysis has the ability to identify the presence of common descending drive shared by motor unit pools and reveals its spectral properties. However, the link between spectral properties of shared neural drive and functional interactions among muscles remains unclear. We assessed shared neural drive between muscles of the thumb and index finger while participants executed two mechanically distinct precision pinch tasks, each requiring distinct functional coordination among muscles. We found that shared neural drive was systematically reduced or enhanced at specific frequencies of interest (~10 and ~40 Hz). While amplitude correlations between surface EMG signals also exhibited changes across tasks, only their coherence has strong physiological underpinnings indicative of neural binding. Our results support the use of intermuscular coherence as a tool to detect when coactivated muscles are members of a functional group or synergy of neural origin. Furthermore, our results demonstrate the advantages of considering neural binding at 10, ~20, and >30 Hz, as indicators of task-dependent neural coordination strategies.

Contemporary Clinical Trials Communications, 7, 86-94. https://doi.org/10.1016/j.conctc.2017.06.004 Show abstract
Background. Childhood obesity continues to be a substantial problem despite major public health efforts, and disproportionately impacts children from low-income families. Digital health tools and consumer technology offer promising opportunities for interventions, but few studies have evaluated how they might be incorporated into existing interventions or used to create new types of interventions. It remains unclear which approaches would be most beneficial for underserved pediatric populations.
Purpose. To describe the design and rationale of a single-center randomized, controlled trial evaluating the effects of personal activity tracker (PAT) use by parents on weight-status improvement in both parents and overweight children enrolled in BodyWorks (BW), a comprehensive behavioral family-lifestyle intervention program (CBFLI), in a primary-care clinic serving a predominantly low-income Latino population.
Methods. This study is being conducted in the AltaMed general pediatrics clinic at Children's Hospital Los Angeles. Eligible participants are families (child and adult caregiver) in which the child is between 7 and 18 years of age, has a BMI ≥85th percentile for age and sex, and has been referred to BW by their AltaMed pediatrician. BW consists of one weekly, two-hour session for 7 weeks. In a given cycle, the program is offered on two separate nights: Monday (Spanish) and Wednesday (English). Families self sort into one of two groups based on language preference. To ensure balanced allocation of language preference groups and prevent in-group cross contamination, block randomization is used to assign whole groups to either the intervention or control arms of the study. The control arm consists of usual care, while the intervention arm adds assigning a Fitbit PAT to the parents and training them in its proper use. Study personnel are blinded to group assignment during the analysis phase. Study outcomes include attendance rate, program completion rate, and changes in weight-status improvement, defined as change in weight and BMI for adults and change in BMI z-score for children. We hypothesize that the intervention arm will have better weight-related outcomes than the control arm. Study completion is anticipated in 2017, after the enrollment of approximately 150 families.
Conclusions. The study aim is to evaluate the effects of PATs on weight-related outcomes in overweight children and parents participating in a CBFLI. The results will be important for determining whether wearable devices are an effective addition to weight loss interventions for overweight and obese children.

This article reports on an ethnographic study with 12 Latino families of children on the autism spectrum related to obtaining autism services in Los Angeles County. Using critical discourse analysis of interviews, observations, and records, we consider the experiences of the Latino families in relation to: a discursively constructed ‘autism parent’ subject position that mandates ‘fighting’ service systems to ‘win’ autism services for children, originating from White middle-class parents’ socioeconomic resources and social capital; a neoliberal social services climate that assumes scarcity of available resources and prioritizes austerity in their authorization; and a media and institutional ‘cultural deficit’ discourse that attributes disparities in autism services for Latino children to their parents’ presumed culturally-based ‘passivity.’ We argue that parental discourse about fighting, or not fighting, for autism services is engendered by a tension between a parental logic of care, and the logic of competition of the economic market.

Research in Autism Spectrum Disorders, 39, 63-72. https://doi.org/10.1016/j.rasd.2017.03.002 Show abstract
Background. Many children with autism spectrum disorders (ASD) experience barriers to oral care in the dental office setting. The purpose of this study was to provide an increased understanding of these challenges experienced during oral care in the dental office by children with ASD.
Method. This study was part of a larger mixed methods design and builds on quantitative results from a survey of parents of children with ASD ages 2–18 in which parents reported difficulties with access to care, sensory processing, and uncooperative behaviors. For this study, we conducted two, three hour, focus groups of parents of male children with ASD age 5–18 years in order to explore the survey results in greater depth. Focus group transcripts were analyzed using a template coding approach based on the three domains of office-based oral care challenges identified in the first phase (survey).
Results. Several related themes emerged including: (1) Access: “Difficult to find the right dentist”, (2) Sensory sensitivities: “All the sensory devices just make him so uncomfortable”, (3) Restraint: “It looked like they were torturing him”, and (4) Drugs: “A mixed bag”.
Conclusions. The qualitative findings from this study both confirmed our previous survey findings and expanded upon them. These findings can help professionals better understand the challenges experienced by children with ASD and their parents as well as help identify priorities for planning efforts to address the oral health-related needs of this population.

Object play in infants with autism spectrum disorder: A longitudinal retrospective video analysis. Autism & Developmental Language Impairments, 2, 1-12. https://doi.org/10.1177/2396941517713186 Show abstract
Background and aims. Early play behaviors may provide important information regarding later-diagnosed developmental delays. Play behaviors of young children with autism spectrum disorder are restricted in diversity, frequency, and complexity. Most autism spectrum disorder research focuses on play in children over 18 months of age. This study examined three groups of infants (later diagnosed with autism spectrum disorder, later diagnosed with other developmental disorders, and typically developing) with the aims of: (1) describing the play behaviors of the three groups of infants at two time points (9–12 months and 15–18 months); (2) examining group differences in four hierarchical levels of play at both time points; (3) comparing groups with respect to the highest level of play achieved; and (4) determining if the highest level of play achieved by infants with autism spectrum disorder and other developmental delays correlated with later developmental outcomes.
Methods. The current study used longitudinal retrospective video analysis to examine object play behaviors of the three groups of infants (total n = 92) at two time points (time 1: 9–12 months of age, and time 2: 15–18 months of age). Coding of play behaviors was based on existing literature and distribution of data from the current study. Developmental outcomes examined were measured using the Vineland Adaptive Behavior Scales, Childhood Autism Rating Scale, and a non-verbal developmental quotient calculated using visual reception scores from the Mullen Scales for Early Learning.
Results. Results indicate group differences in play, with infants later diagnosed with autism spectrum disorder showing significantly less sophisticated play than those with typical development. In addition, modest but significant correlations were found between highest level of play achieved at time 1 (9–12 months) and time 2 (15–18 months) and later outcomes for the autism spectrum disorder group.
Conclusions and implications. Results suggest that examination of infant play behaviors is important for early screening and intervention planning to potentially mitigate effects on later developmental outcomes.

Pronounced heterogeneity is apparent across every facet of autism spectrum disorder (ASD) and it remains difficult to predict likely future potential among individuals who share a common diagnosis of ASD on the basis of early presentation. In this commentary we argue that a fine-grained understanding of individual differences in sensory features and their influence across the life span can constrain noted clinical heterogeneity in ASD. We organize our discussion around the following three critical themes: (a) considering sensory features as dimensional construct; (b) taking an "individual differences" approach; and (c) adopting a comprehensive, multidimensional and multimodal approach to measurement of sensory features. We conclude that future research will need to investigate individual differences in sensory features via: (1) multidimensional and cross-disciplinary examination, (2) prospective longitudinal designs, and (3) dimensional and developmental frameworks that emphasize the potential value of early individual variability as indicators of later outcomes, not only in relation to the categorical diagnostic outcome status but also the presence of other clinical features. This is a key time for sensory-related research and in this commentary we provide some of the steps that, in our opinion, can shape future research in this area.

Objective. Our objective was to determine the efficacy of a Lifestyle Redesign® intervention for people living with chronic pain on quality of life (QOL), function, self-efficacy, and pain levels.
Method. Clinical outcomes were collected from 45 patients who completed an individual outpatient Lifestyle Redesign occupational therapy program for chronic pain as part of their usual plan of medical care. Outcome measures included the Canadian Occupational Performance Measure, the 36-Item Short-Form Survey, the Brief Pain Inventory, and the Pain Self-Efficacy Questionnaire. We analyzed scores using paired-samples t tests.
Results. Significant changes were observed in occupational performance and satisfaction scores, physical and social functioning, role limitations due to physical and emotional problems, energy and fatigue, general health, and pain self-efficacy.
Conclusion. Lifestyle Redesign interventions, when integrated into a patient's medical plan of care, can improve patient functioning, self-efficacy, and QOL.

Insight processes that peak in “unpredictable moments of exceptional thinking” are often referred to as Aha! or Eureka moments. During insight, connections between previously unrelated concepts are made and new patterns arise at the perceptual level while new solutions to apparently insolvable problems suddenly emerge to consciousness. Given its unpredictable nature, the definition, and behavioral and neurophysiological measurement of insight problem solving represent a major challenge in contemporary cognitive neuroscience. Numerous attempts have been made, yet results show limited consistency across experimental approaches. Here we provide a comprehensive overview of available neuroscience of insight, including: i) a discussion about the theoretical definition of insight and an overview of the most widely accepted theoretical models, including those debating its relationship with creativity and intelligence; ii) an overview of available tasks used to investigate insight; iii) an ad-hoc quantitative meta-analysis of functional magnetic resonance imaging studies investigating the Eureka moment, using activation likelihood estimation maps; iv) a review of electroencephalographic evidence in the time and frequency domains, as well as v) an overview of the application of non-invasive brain stimulation techniques to causally assess the neurobiological basis of insight as well as enhance insight-related cognition.

Poor sleep contributes to adverse health outcomes making it important to understand sleep in medically vulnerable populations, including those with spinal cord injury (SCI). However, little attention has been paid to circumstances specific to SCI that may negatively affect sleep, or to consequences of poor sleep in this population. The objective of this study was to examine the experience of sleep among individuals with SCI. Secondary analysis using thematic coding of qualitative data from an ethnographic study of community-dwelling adults with SCI was conducted. Sleep-related data were found in transcripts for 90% of the sample. Participants described diminished sleep duration and irregular sleep patterns. Several factors contributing to poor sleep were identified, including SCI-related circumstances and sleep environment. Participants also discussed how poor sleep affected occupational engagement. This study highlights the extent of sleep disturbance experienced after SCI and the subsequent impact on occupational performance, and provides direction for clinical practice.

During force production, hand muscle activity is known to be coherent with activity in primary motor cortex, specifically in the beta-band (15–30 Hz) frequency range. It is not clear, however, if this coherence reflects the control strategy selected by the nervous system for a given task, or if it instead reflects an intrinsic property of cortico-spinal communication. Here, we measured corticomuscular and intermuscular coherence between muscles of index finger and thumb while a two-finger pinch grip of identical net force was applied to objects which were either stable (allowing synergistic activation of finger muscles) or unstable (requiring individuated finger control). We found that beta-band corticomuscular coherence with the first dorsal interosseous (FDI) and abductor pollicis brevis (APB) muscles, as well as their beta-band coherence with each other, was significantly reduced when individuated control of the thumb and index finger was required. We interpret these findings to show that beta-band coherence is reflective of a synergistic control strategy in which the cortex binds task-related motor neurons into functional units.

An infant’s vocal capacity develops significantly during the first year of life. Research suggests early measures of pre-speech development, such as canonical babbling and volubility, can differentiate typical versus disordered development. This study offers a new contribution by comparing early vocal development in 10 infants with Fragile X syndrome and 14 with typical development. Results suggest infants with Fragile X syndrome produce fewer syllables and have significantly lower canonical babbling ratios compared to infants who are typically developing. Furthermore, the particular measures of babbling were strong predictors of group membership, adding evidence regarding the possible utility of these markers in early identification.

Immersive, head-mounted virtual reality (HMD-VR) provides a unique opportunity to understand how changes in sensory environments affect motor learning. However, potential differences in mechanisms of motor learning and adaptation in HMD-VR versus a conventional training (CT) environment have not been extensively explored. Here, we investigated whether adaptation on a visuomotor rotation task in HMD-VR yields similar adaptation effects in CT and whether these effects are achieved through similar mechanisms. Specifically, recent work has shown that visuomotor adaptation may occur via both an implicit, error-based internal model and a more cognitive, explicit strategic component. We sought to measure both overall adaptation and balance between implicit and explicit mechanisms in HMD-VR versus CT. Twenty-four healthy individuals were placed in either HMD-VR or CT and trained on an identical visuomotor adaptation task that measured both implicit and explicit components. Our results showed that the overall timecourse of adaption was similar in both HMD-VR and CT. However, HMD-VR participants utilized a greater cognitive strategy than CT, while CT participants engaged in greater implicit learning. These results suggest that while both conditions produce similar results in overall adaptation, the mechanisms by which visuomotor adaption occurs in HMD-VR appear to be more reliant on cognitive strategies.

Pathological tremors are involuntary oscillatory movements which cannot be fully attenuated using conventional treatments. For this reason, several studies have investigated the use of neuromuscular electrical stimulation for tremor suppression. In a recent study, however, we found that electrical stimulation below the motor threshold also suppressed tremor, indicating involvement of afferent pathways. In this study, we further explored this possibility by systematically investigating how tremor suppression by afferent stimulation depends on the stimulation settings. In this way, we aimed at identifying the optimal stimulation strategy, as well as to elucidate the underlying physiological mechanisms of tremor suppression. Stimulation strategies varying the stimulation intensity and pulse timing were tested in nine tremor patients using either intramuscular or surface stimulation. Significant tremor suppression was observed in six patients (tremor suppression > 75% was observed in three patients) and the average optimal suppression level observed across all subjects was 52%. The efficiency for each stimulation setting, however, varied substantially across patients and it was not possible to identify a single set of stimulation parameters that yielded positive results in all patients. For example, tremor suppression was achieved both with stimulation delivered in an out-of-phase pattern with respect to the tremor, and with random timing of the stimulation. Overall, these results indicate that low-current stimulation of afferent fibers is a promising approach for tremor suppression, but that further research is required to identify how the effect can be maximized in the individual patient.

Journal of Autism and Developmental Disorders, 47(3), 834-845. https://doi.org/10.1007/s10803-016-2996-x Show abstract
Genetic liability to autism spectrum disorder (ASD) can be expressed in unaffected relatives through subclinical, genetically meaningful traits, or endophenotypes. This study aimed to identify developmental endophenotypes in parents of individuals with ASD by examining parents' childhood academic development over the school-age period. A cohort of 139 parents of individuals with ASD were studied, along with their children with ASD and 28 controls. Parents' childhood records in the domains of language, reading, and math were studied from grades K-12. Results indicated that relatively lower performance and slower development of skills (particularly language related skills), and an uneven rate of development across domains predicted ASD endophenotypes in adulthood for parents, and the severity of clinical symptoms in children with ASD. These findings may mark childhood indicators of genetic liability to ASD in parents, that could inform understanding of the subclinical expression of ASD genetic liability.

We examined rural-urban differences in emergency department visits, and child and clinical characteristics associated with visits for U.S. children aged 3-17 years with autism spectrum disorder (ASD). Rural children with ASD were twice more likely to have emergency department visits in urban hospitals than rural children without ASD. The children with ASD in rural areas were economically disadvantaged and concentrated in the South and Midwest regions. Rural children diagnosed with ASD and multiple comorbidities during emergency department visits were 1.6 times as that of urban children. Rural children with ASD, particularly those with multiple comorbidities, require more emergency department services when compared with urban children with ASD.

Occupational therapists and occupational scientists are committed to generating and using knowledge about occupation, but Western middle-class social norms regarding particular ways of doing have limited explorations of survival occupations. This article provides empirical evidence of the ways in which resource seeking constitutes an occupational response to situations of uncertain survival. Resource seeking includes a range of activities outside formal employment that aim to meet basic needs. On the basis of findings from 2 ethnographic studies, we critique the presumption of survival in guiding occupational therapy documents and the accompanying failure to recognize occupations that seem at odds with self-sufficiency. We argue that failing to name resource seeking in occupational therapy documents risks alignment with social, political, and economic trends that foster occupational injustices. If occupational therapists truly aim to meet society’s occupational needs, they must ensure that professional documents and discourses reflect the experiences of all people in society.
Martinez‐Valdes, E., Negro, F., Laine, C. M., Falla, D., Mayer, F., & Farina, D. (2017). Tracking motor units longitudinally across experimental sessions with high‐density surface electromyography. The Journal of Physiology, 595(5), 1479-1496. https://doi.org/10.1113/JP273662 Show abstract
A new method is proposed for tracking individual motor units (MUs) across multiple experimental sessions on different days. The technique is based on a novel decomposition approach for high‐density surface electromyography and was tested with two experimental studies for reliability and sensitivity. Experiment I (reliability): ten participants performed isometric knee extensions at 10, 30, 50 and 70% of their maximum voluntary contraction (MVC) force in three sessions, each separated by 1 week. Experiment II (sensitivity): seven participants performed 2 weeks of endurance training (cycling) and were tested pre–post intervention during isometric knee extensions at 10 and 30% MVC. The reliability (Experiment I) and sensitivity (Experiment II) of the measured MU properties were compared for the MUs tracked across sessions, with respect to all MUs identified in each session. In Experiment I, on average 38.3% and 40.1% of the identified MUs could be tracked across two sessions (1 and 2 weeks apart), for the vastus medialis and vastus lateralis, respectively. Moreover, the properties of the tracked MUs were more reliable across sessions than those of the full set of identified MUs (intra‐class correlation coefficients ranged between 0.63—0.99 and 0.39–0.95, respectively). In Experiment II, ∼40% of the MUs could be tracked before and after the training intervention and training‐induced changes in MU conduction velocity had an effect size of 2.1 (tracked MUs) and 1.5 (group of all identified motor units). These results show the possibility of monitoring MU properties longitudinally to document the effect of interventions or the progression of neuromuscular disorders.

Clinical and psychosocial outcomes of a structured transition program among young adults with type 1 diabetes. Journal of Adolescent Health, 60(2), 212-218. https://doi.org/10.1016/j.jadohealth.2016.09.004 Show abstract
Purpose. We identified and treated young adults with type 1 diabetes who had been lost to follow-up during their transfer from pediatric to adult care, comparing their clinical, psychosocial, and health care utilization outcomes to participants receiving continuous care (CC) throughout the transition to adult care.
Methods. Individuals in their last year of pediatric care (CC group, n = 51) and individuals lost to follow-up in the transfer to adult care ("lapsed care" [LC] group, n = 24) were followed prospectively for 12 months. All participants were provided developmentally tailored diabetes education, case management, and clinical care through a structured transition program.
Results. At baseline, LC participants reported lapses in care of 11.6 months. Compared with CC participants, they had higher hemoglobin A1C (A1C; p = .005), depressive symptoms (p = .05), incidence of severe hypoglycemia (p = .005), and emergency department visits (p = .004). At 12-month follow-up, CC and LC participants did not differ on the number of diabetes care visits (p = .23), severe hypoglycemia (no events), or emergency department visits (p = .22). Both groups' A1C improved during the study period (CC: p = .03; LC: p = .02). LC participants' depressive symptoms remained elevated (p = .10), and they reported a decline in life satisfaction (p = .007). There was greater loss to follow-up in the LC group (p = .04).
Conclusions. Our study suggests that, for young adults with a history of lapses in care, a structured transition program is effective in lowering A1C, reducing severe hypoglycemia and emergency department utilization, and improving uptake of routine diabetes care. Loss to follow-up and psychosocial concerns remain significant challenges in this population.

Atypical sensory and repetitive behaviors are defining features of autism spectrum disorder and are thought to be influenced by environmental factors; however, there is a lack of naturalistic research exploring contexts surrounding these behaviors. This study involved video recording observations of 32 children with autism spectrum disorder (2-12 years of age) engaging in sensory and repetitive behaviors during home activities. Behavioral coding was used to determine what activity contexts, sensory modalities, and stimulus characteristics were associated with specific behavior types: hyperresponsive, hyporesponsive, sensory seeking, and repetitive/stereotypic. Results indicated that hyperresponsive behaviors were most associated with activities of daily living and family-initiated stimuli, whereas sensory seeking behaviors were associated with free play activities and child-initiated stimuli. Behaviors associated with multiple sensory modalities simultaneously were common, emphasizing the multi-sensory nature of children's behaviors in natural contexts. Implications for future research more explicitly considering context are discussed.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method to modulate the local field potential in neural tissue and consequently, cortical excitability. As tDCS is relatively portable, affordable, and accessible, the applications of tDCS to probe brain-behavior connections have rapidly increased in the last 10 years. One of the most promising applications is the use of tDCS to modulate excitability in the motor cortex after stroke and promote motor recovery. However, the results of clinical studies implementing tDCS to modulate motor excitability have been highly variable, with some studies demonstrating that as many as 50% or more of patients fail to show a response to stimulation. Much effort has therefore been dedicated to understand the sources of variability affecting tDCS efficacy. Possible suspects include the placement of the electrodes, task parameters during stimulation, dosing (current amplitude, duration of stimulation, frequency of stimulation), individual states (e.g., anxiety, motivation, attention), and more. In this review, we first briefly review potential sources of variability specific to stroke motor recovery following tDCS. We then examine how the anatomical variability in tDCS placement [e.g., neural target(s) and montages employed] may alter the neuromodulatory effects that tDCS exerts on the post-stroke motor system.
Lefebvre, S., Dricot, L., Laloux, P., Desfontaines, P., Evrard, F., Peeters, A., Jamart, J., & Vandermeeren, Y. (2017). Increased functional connectivity one week after motor learning and tDCS in stroke patients. Neuroscience, 340, 424-435. https://doi.org/10.1016/j.neuroscience.2016.10.066 Show abstract
Recent studies using resting-state functional magnetic resonance imaging (rs-fMRI) demonstrated that changes in functional connectivity (FC) after stroke correlate with recovery. The aim of this study was to explore whether combining motor learning to dual transcranial direct current stimulation (dual-tDCS, applied over both primary motor cortices (M1)) modulated FC in stroke patients. Twenty-two chronic hemiparetic stroke patients participated in a baseline rs-fMRI session. One week later, dual-tDCS/sham was applied during motor skill learning (intervention session); one week later, the retention session started with the acquisition of a run of rs-fMRI imaging. The intervention + retention sessions were performed once with dual-tDCS and once with sham in a randomized, cross-over, placebo-controlled, double-blind design. A whole-brain independent component analysis based analysis of variance (ANOVA) demonstrated no changes between baseline and sham sessions in the somatomotor network, whereas a FC increase was observed one week after dual-tDCS compared to baseline (qFDR <0.05, t63 = 4.15). A seed-based analysis confirmed specific stimulation-driven changes within a network of motor and premotor regions in both hemispheres. At baseline and one week after sham, the strongest FC was observed between the M1 and dorsal premotor cortex (PMd) of the undamaged hemisphere. In contrast, one week after dual-tDCS, the strongest FC was found between the M1 and PMd of the damaged hemisphere. Thus, a single session of dual-tDCS combined with motor skill learning increases FC in the somatomotor network of chronic stroke patients for one week.

Musculoskeletal sonography is rapidly extending beyond radiology; however, best practices for successful integration into new practice contexts are unknown. This study explored non-physician experiences with the processes of training and integration of musculoskeletal sonography into rehabilitation. Qualitative data were captured through multiple sources, and iterative thematic analysis was used to describe two occupational therapists' experiences. The dominant emerging theme was competency, in three domains: technical, procedural, and analytical. In addition, three practice considerations were illuminated: (a) understanding imaging within the dynamics of rehabilitation, (b) navigating nuances of interprofessional care, and (c) implications for post-professional training. Findings indicate that sonography training for rehabilitation providers requires multi-level competency development and consideration of practice complexities. These data lay a foundation on which to explore and develop best practices for incorporating sonographic imaging into the clinic as a means for engaging clients as active participants in the rehabilitation process to improve health and rehabilitation outcomes.

Pediatric occupational therapy practitioners frequently provide interventions for children with differences in sensory processing and integration. Confusion exists regarding how best to intervene with these children and about how to describe and document methods. Some practitioners hold the misconception that Ayres Sensory Integration intervention is the only approach that can and should be used with this population. The issue is that occupational therapy practitioners must treat the whole client in varied environments; to do so effectively, multiple approaches to intervention often are required. This article presents a framework for conceptualizing interventions for children with differences in sensory processing and integration that incorporates multiple evidence-based approaches. To best meet the needs of the children and families seeking occupational therapy services, interventions must be focused on participation and should be multifaceted.

Assessing fatigability in the lab and in daily life in older adults with osteoarthritis using perceived, performance, and ecological measures. The Journals of Gerontology Series A: Biological Science and Medical Sciences, 72(1), 115-120. https://doi.org/10.1093/gerona/glw173 Show abstract
Background. Fatigue in older adults is associated with functional decline and reduced participation in daily life; however, it is not well characterized. Examining fatigue within activity performance, or "fatigability," is a recommended approach to begin to understand fatigue and its underlying mechanisms. This study examined the construct validity of lab-based measures of fatigability and compared these measures with fatigability in daily life (termed ecological fatigability).
Methods. Participants with osteoarthritis and fatigue (n = 163) underwent laboratory assessments, completed questionnaires, and wore accelerometers for 7 days while tracking symptoms and behaviors. Lab-based fatigability measures were quantified using the 6-minute walk test. Perceived fatigability was assessed by asking participants before and after the test to report: (i) fatigue severity and (ii) perceived exertion. Performance fatigability was calculated using change in walking speed divided by total distance walked. Ecological fatigability was calculated from the 7-day assessment in which fatigue severity was reported five times a day and physical activity was continuously measured. Additional ecological measures (eg, self-pacing) were examined.
Results. Lab-based perceived and performance fatigability measures were highly inter-correlated, moderately correlated with gait speed and metabolic measures, and weakly correlated with physical activity. Although ecological fatigability was weakly correlated with lab-based measures, participants with high fatigability on lab-based measures demonstrated more self-pacing behaviors than participants with low fatigability.
Conclusion. Lab-based fatigability measures are related to physical capacity measured both in the lab and daily life. Lab-based fatigability measures provide important information regarding daily life fatigability useful for future intervention development.

Predictors of parent responsiveness to 1-year-olds at-risk for autism spectrum disorder. Journal of Autism and Developmental Disorders, 47(1), 172-186. https://doi.org/10.1007/s10803-016-2944-9 Show abstract
Parent responsiveness is critical for child development of cognition, social-communication, and self-regulation. Parents tend to respond more frequently when children at-risk for autism spectrum disorder (ASD) demonstrate stronger social-communication; however, it is unclear how responsiveness is associated with sensory characteristics of children at-risk for ASD. To address this issue, we examined the extent to which child social-communication and sensory reactivity patterns (i.e., hyper- and hypo-reactivity) predicted parent responsiveness to 1-year-olds at-risk for ASD in a community sample of 97 parent-infant pairs. A combination of child social-communication and sensory hypo-reactivity consistently predicted how parents played and talked with their 1-year-old at-risk for ASD. Parents tended to talk less and use more play actions when infants communicated less and demonstrated stronger hypo-reactivity.

Occupational therapy practitioners are key health care providers for people with musculoskeletal disorders of the distal upper extremity. It is imperative that practitioners understand the most effective and efficient means for remediating impairments and supporting clients in progressing to independence in purposeful occupations. This systematic review provides an update to a previous review by summarizing articles published between 2006 and July 2014 related to the focused question, What is the evidence for the effect of occupational therapy interventions on functional outcomes for adults with musculoskeletal disorders of the forearm, wrist, and hand? A total of 59 articles were reviewed. Evidence for interventions was synthesized by condition within bone, joint, and general hand disorders; peripheral nerve disorders; and tendon disorders. The strongest evidence supports postsurgical early active motion protocols and splinting for various conditions. Very few studies have examined occupation-based interventions. Implications for occupational therapy practice and research are provided.

Work-related musculoskeletal disorders are a significant burden; however, no consensus has been reached on how to maximize occupational rehabilitation programs for people with these disorders, and the impact of simulating work tasks as a mode of intervention has not been well examined. In this retrospective cohort study, the authors used logistic regression to identify client and program factors predicting success for 95 clients in a general occupational rehabilitation program and 71 clients in a comprehensive occupational rehabilitation program. The final predictive model for general rehabilitation included gender, number of sessions completed, and performance of work simulation activities. Maximum hours per session was the only significant predictor of success in the comprehensive rehabilitation program. This study identifies new factors associated with success in occupational rehabilitation, specifically highlighting the importance of intensity (i.e., session length and number of sessions) of therapy and occupation-based activities for this population.

Modifying sensory aspects of the learning environment can influence motor behavior. Although the effects of sensory manipulations on motor behavior have been widely studied, there still remains a great deal of variability across the field in terms of how sensory information has been manipulated or applied. Here, the authors briefly review and integrate the literature from each sensory modality to gain a better understanding of how sensory manipulations can best be used to enhance motor behavior. Then, they discuss 2 emerging themes from this literature that are important for translating sensory manipulation research into effective interventions. Finally, the authors provide future research directions that may lead to enhanced efficacy of sensory manipulations for motor learning and rehabilitation.

Integration of research in the fields of neural control of movement and biomechanics (collectively referred to as movement science) with the field of human occupation directly benefits both areas of study. Specifically, incorporating many of the quantitative scientific methods and analyses employed in movement science can help accelerate the development of rehabilitation-relevant research in occupational therapy (OT) and occupational science (OS). Reciprocally, OT and OS, which focus on the performance of everyday activities (occupations) to promote health and well-being, provide theoretical frameworks to guide research on the performance of actions in the context of social, psychological, and environmental factors. Given both fields' mutual interest in the study of movement as it relates to health and disease, the authors posit that combining OS and OT theories and principles with the theories and methods in movement science may lead to new, impactful, and clinically relevant knowledge. The first step is to ensure that individuals with OS or OT backgrounds are academically prepared to pursue advanced study in movement science. In this article, the authors propose 2 strategies to address this need.

Resilient, Empowered, Active Living with Diabetes (REAL Diabetes) study: Methodology and baseline characteristics of a randomized controlled trial evaluating an occupation-based diabetes management intervention for young adults. Contemporary Clinical Trials, 54, 8-17. https://doi.org/10.1016/j.cct.2016.12.025 Show abstract
Overview. This paper describes the study protocol used to evaluate the Resilient, Empowered, Active Living with Diabetes (REAL Diabetes) intervention and reports on baseline characteristics of recruited participants. REAL Diabetes is an activity-based intervention designed to address the needs of young adults diagnosed with type 1 (T1D) or type 2 diabetes (T2D) from low socioeconomic status or racial/ethnic minority backgrounds. The REAL intervention incorporates tailored delivery of seven content modules addressing various dimensions of health and well-being as they relate to diabetes, delivered by a licensed occupational therapist.
Methods. In this pilot randomized controlled trial, participants are assigned to the REAL Diabetes intervention or an attention control condition. The study's primary recruitment strategies included in-person recruitment at diabetes clinics, mass mailings to clinic patients, and social media advertising. Data collection includes baseline and 6-month assessments of primary outcomes, secondary outcomes, and hypothesized mediators of intervention effects, as well as ongoing process evaluation assessment to ensure study protocol adherence and intervention fidelity.
Results. At baseline, participants (n=81) were 51% female, 78% Latino, and on average 22.6years old with an average HbA1c of 10.8%. A majority of participants (61.7%) demonstrated clinically significant diabetes distress and 27.2% reported symptoms consistent with major depressive disorder. Compared to participants with T1D, participants with T2D had lower diabetes-related self-efficacy and problem-solving skills. Compared to participants recruited at clinics, participants recruited through other strategies had greater diabetes knowledge but weaker medication adherence.
Discussion. Participants in the REAL study demonstrate clinically significant medical and psychosocial needs.

People with musculoskeletal disorders of the shoulder commonly experience pain, decreased strength, and restricted range of motion (ROM) that limit participation in meaningful occupational activities. The purpose of this systematic review was to evaluate the current evidence for interventions within the occupational therapy scope of practice that address pain reduction and increase participation in functional activities. Seventy-six studies were reviewed for this study-67 of Level I evidence, 7 of Level II evidence, and 2 of Level III evidence. Strong evidence was found that ROM, strengthening exercises, and joint mobilizations can improve function and decrease pain. The evidence to support physical modalities is moderate to mixed, depending on the shoulder disorder. Occupational therapy practitioners can use this evidence to guide daily clinical decision making.
