OBJECTIVE: The study's objective was to evaluate the effectiveness of the Interdisciplinary Sensory-Enriched Early Intervention (ISEEI) group program for children with developmental delays.
METHOD: We conducted a retrospective chart review of 63 children ages 18-36 mo who participated in ISEEI. We evaluated participants with the Bayley Scales of Infant and Toddler Development III (Bayley-III) and the Infant/Toddler Sensory Profile (ITSP) at enrollment and after 3-9 mo. We conducted a paired t test to examine changes in the Bayley-III between pre- and posttests.
RESULTS: At enrollment, 70% of children presented atypical scores in two or more areas of sensory processing in the ITSP. Results revealed that children with sensory processing difficulties demonstrated significant improvement in all areas of development except fine motor skills; children without sensory processing difficulties showed significant improvement in language and cognition.
CONCLUSION: The ISEEI group program is an effective method to ameliorate developmental delays.

OBJECTIVE: Prior research has documented caregiving difficulties in families of children with autism spectrum disorder (ASD). However, Latino families may encounter unique challenges. The purpose of this study was to understand the caregiving experiences of Latino families with children with ASD, including daily activities, coping strategies, and service utilization.
METHOD: Fifteen Latino parents of children with ASD were interviewed. The interviews were transcribed for analysis to identify themes of experiences unique to this population.
RESULTS: Latino families of children with ASD encounter many similar issues as non-Latino families but also unique issues that affect service utilization. Four themes were identified: dealing with the diagnosis, dealing with stigma and isolation from family and community, understanding the role of mothers in changing family routines, and utilizing services.
CONCLUSION: To meet the unique needs of Latino families, services need to be provided in culturally sensitive context that address children's needs within family units.

Pressure ulcers (PrUs) are a major burden to patients with spinal cord injury (SCI), affecting their psychological, physical, and social well-being. Lifestyle choices are thought to contribute to the risk of developing PrUs. This article focuses on the interaction between lifestyle choices and the development of PrUs in community settings among participants in the University of Southern California-Rancho Los Amigos National Rehabilitation Center Pressure Ulcer Prevention Study (PUPS II), a randomized controlled trial of a lifestyle intervention for adults with SCI. We conducted a secondary cross-case analysis of treatment notes of 47 PUPS II participants and identified four patterns relating PrU development to lifestyle changes: positive PrU changes (e.g., healing PrUs) with positive lifestyle changes, negative or no PrU changes with positive lifestyle changes, positive PrU changes with minor lifestyle changes, and negative or no PrU changes with no lifestyle changes. We present case studies exemplifying each pattern.

OBJECTIVE: We investigated sensory integration (SI) function in children with cochlear implants (CIs).
METHOD: We analyzed deidentified records from 49 children ages 7 mo to 83 mo with CIs. Records included Sensory Integration and Praxis Tests (SIPT), Sensory Processing Measure (SPM), Sensory Profile (SP), Developmental Profile 3 (DP-3), and Peabody Developmental Motor Scales (PDMS), with scores depending on participants' ages. We compared scores with normative population mean scores and with previously identified patterns of SI dysfunction.
RESULTS: One-sample t tests revealed significant differences between children with CIs and the normative population on the majority of the SIPT items associated with the vestibular and proprioceptive bilateral integration and sequencing (VPBIS) pattern. Available scores for children with CIs on the SPM, SP, DP-3, and PDMS indicated generally typical ratings.
CONCLUSION: SIPT scores in a sample of children with CIs reflected the VPBIS pattern of SI dysfunction, demonstrating the need for further examination of SI functions in children with CIs during occupational therapy assessment and intervention planning.

This article describes the development of the Adult Sensory Processing Scale (ASPS), a sensory processing questionnaire for adults. The ASPS measures self-reported responses to input from distinct sensory systems and is intended to be sensitive to individual differences in the adult population. ASPS construction involved two phases: item development and instrument construction. During item development, content validity of 71 items was assessed by means of expert ratings. During instrument construction, items were evaluated using data from an online survey of 491 adults. Exploratory factor analysis and Rasch analysis yielded an optimal solution of eight factors representing vestibular overresponsiveness, auditory overresponsiveness, visual overresponsiveness, social tactile overresponsiveness, proprioceptive seeking, general underresponsiveness, vestibular—proprioceptive underresponsiveness affecting postural control, and vestibular overresponsiveness—intolerance to movement. The final ASPS contains 39 items and demonstrates acceptable internal consistency, strong content validity, and adequate construct validity.

BACKGROUND: Randomized trials of complex, non-pharmacologic interventions implemented in home and community settings, such as the University of Southern California (USC)-Rancho Los Amigos National Rehabilitation Center (RLANRC) Pressure Ulcer Prevention Study (PUPS), present unique challenges with respect to (1) participant recruitment and retention, (2) intervention delivery and fidelity, (3) randomization and assessment, and (4) potential inadvertent treatment effects.
PURPOSE: We describe the methods employed to address the challenges confronted in implementing PUPS. In this randomized controlled trial, we are assessing the efficacy of a complex, preventive intervention in reducing the incidence of, and costs associated with, the development of medically serious pressure ulcers in people with spinal cord injury.
METHODS: Individuals with spinal cord injury recruited from RLANRC were assigned to either a 12-month preventive intervention group or a standard care control group. The primary outcome is the incidence of serious pressure ulcers with secondary endpoints including ulcer-related surgeries, medical treatment costs, and quality of life. These outcomes are assessed at 12 and 24 months after randomization. Additionally, we are studying the mediating mechanisms that account for intervention outcomes.
RESULTS: PUPS has been successfully implemented, including recruitment of the target sample size of 170 participants, assurance of the integrity of intervention protocol delivery with an average 90% treatment adherence rate, and enactment of the assessment plan. However, implementation has been replete with challenges. To meet recruitment goals, we instituted a five-pronged approach customized for an underserved, ethnically diverse population. In intervention delivery, we increased staff time to overcome economic and cultural barriers to retention and adherence. To ensure treatment fidelity and replicability, we monitored intervention protocol delivery in accordance with a rigorous plan. Finally, we have overcome unanticipated assessment and design concerns related to (1) determining pressure ulcer incidence/severity, (2) randomization imbalance, and (3) inadvertent potential control group contamination.
LIMITATIONS: We have addressed the most daunting challenges encountered in the recruitment, assessment, and intervention phases of PUPS. Some challenges and solutions may not apply to trials conducted in other settings.
CONCLUSIONS: Overcoming challenges has required a multifaceted approach incorporating individualization, flexibility, and persistence, as well as the ability to implement needed mid-course corrections.

Implementation into real-world practice of interventions previously studied in randomized controlled trials is an ongoing challenge. In this article, we describe the methodology we used for the first phase of a project for the implementation and outcomes assessment of an occupational therapy pressure ulcer prevention intervention for people with spinal cord injury in the Veterans Health Administration. This first phase of the project was guided by practice-based evidence research methodology and resulted in an intervention manual tailored to meet the needs of Veterans and the establishment of a system for documenting and monitoring care processes, patient characteristics, and intervention outcomes. This system, in turn, will provide the data-gathering template for the next phase in which the beneficial effects of the intervention will be assessed. We conclude by recommending that clinicians explore the utility of this approach for the implementation of other novel interventions.

Randomized controlled trials (RCTs) are considered the criterion standard in research design for establishing treatment efficacy. However, the rigorous and highly controlled conditions of RCTs can be difficult to attain when conducting research among individuals living with a confluence of disability, low socioeconomic status, and being a member of a racial/ethnic minority group, who may be more likely to have unstable life circumstances. Research on effective interventions for these groups is urgently needed, because evidence regarding approaches to reduce health disparities and improve health outcomes is lacking. In this methodologic article, we discuss the challenges and lessons learned in implementing the Lifestyle Redesign for Pressure Ulcer Prevention in Spinal Cord Injury study among a highly disadvantaged population. These issues are discussed in terms of strategies to enhance recruitment, retention, and intervention relevance to the target population. Recommendations for researchers seeking to conduct RCTs among socioeconomically disadvantaged, ethnically diverse populations are provided.

American Journal of Occupational Therapy, 66, 567-576. http://dx.doi.org/10.5014/ajot.2012.004242. Link to full text Abstract →
OBJECTIVES: We examined whether children with and without autism spectrum disorder (ASD) differ in autonomic activity at rest and in response to auditory stimuli and whether behavioral problems related to sounds in everyday life are associated with autonomic responses to auditory stimuli.
METHOD: We measured skin conductance (SC) at rest and in response to auditory stimuli as well as behavioral responses using the Sensory Processing Measure (SPM) Home Form. Participants were 25 children with ASD and 25 typically developing (TD) children, aged 5–12 yr.
RESULTS: The ASD group had significantly higher resting SC and stronger SC reactivity to tones than the TD group. Correlations between SC and SPM indicated that more severe auditory behavioral difficulties were associated with higher sympathetic activation at rest and stronger sympathetic reactivity to sound.
CONCLUSION: High sympathetic reactivity to sound may underlie the difficult behavioral responses to sound that children with ASD often demonstrate.

OBJECTIVE: We developed an observational tool, the Comprehensive Observations of Proprioception (COP), for identifying proprioceptive processing issues in children with developmental disabilities.
METHOD: Development of the COP underwent three phases. First, we developed items representing proprioceptive functions on the basis of an extensive literature review and consultation with occupational therapists. We then established interrater reliability and content, construct, and criterion validity. Finally, we completed a factor analysis of COP ratings of 130 children with known developmental disabilities.
RESULTS: Adequate validity and reliability were established. Factor analysis revealed a four-factor model that explained the underlying structure of the measure as it was hypothesized.
CONCLUSION: The COP is a valid criterion-referenced short observational tool that structures the clinician’s observations by linking a child’s behaviors to areas identified in the literature as relevant to proprioceptive processing. It takes 15 min to administer and can be used in a variety of contexts, such as the home, clinic, and school.

OBJECTIVE: Sensory processing difficulties among children with autism spectrum disorders (ASD) have been extensively documented. However, less is known about this population’s ability to process proprioceptive information.
METHOD: We used the Comprehensive Observations of Proprioception (COP; Blanche, Bodison, Chang, & Reinoso, in press) to describe the proprioceptive difficulties experienced by children with ASD. A sample of 32 children with ASD, 26 children with developmental disabilities excluding ASD, and 28 typically developing control children were studied using the COP.
RESULTS: Children with ASD present with proprioceptive processing difficulties that are different from those of children with developmental disabilities and their typically developing counterparts. Specific data, potential clinical applications, and directions for future research are described.
CONCLUSION: Results suggest that the COP has useful clinical research applications. Further assessment of psychometric properties, clinical utility, and meaningful differences among diverse clinical populations are needed.

Link to full text Abstract →
Building on established relationships between the constructs of sensory integration in typical and special needs populations, in this retrospective study we examined patterns of sensory integrative dysfunction in 273 children ages 4–9 who had received occupational therapy evaluations in two private practice settings. Test results on the Sensory Integration and Praxis Tests, portions of the Sensory Processing Measure representing tactile overresponsiveness, and parent report of attention and activity level were included in the analyses. Exploratory factor analysis identified patterns similar to those found in early studies by Ayres (1965, 1966a, 1966b, 1969, 1972b, 1977, & 1989), namely Visuodyspraxia and Somatodyspraxia, Vestibular and Proprioceptive Bilateral Integration and Sequencing, Tactile and Visual Discrimination, and Tactile Defensiveness and Attention. Findings reinforce associations between constructs of sensory integration and assist with understanding sensory integration disorders that may affect childhood occupation. Limitations include the potential for subjective interpretation in factor analysis and inability to adjust measures available in charts in a retrospective research.

The manualization of a complex occupational therapy intervention is a crucial step in ensuring treatment fidelity for both clinical application and research purposes. Toward the latter end, intervention manuals are essential for ensuring trustworthiness and replicability of randomized controlled trials that aim to provide evidence of the effectiveness of occupational therapy. In this article, we review the literature on the process of intervention manualization. We then illustrate the prescribed steps through our experience in implementing the University of Southern California/Rancho Los Amigos National Rehabilitation Center's collaborative Pressure Ulcer Prevention Project. In this research program, qualitative research provided the initial foundation for manualization of a multifaceted occupational therapy intervention designed to reduce the incidence of medically serious pressure ulcers in adults with spinal cord injury.

OBJECTIVE: The objectives of the study were to sensitize practitioners working with individuals with spinal cord injury (SCI) to the complex life circumstances that are implicated in the development of pressure ulcers (PrUs) and to document the ways that interventions can be adapted to target individual needs.
METHODS: This study was a content analysis of weekly fidelity/quality control meetings that were undertaken as part of a lifestyle intervention for PrU prevention in community-dwelling adults with SCI.
RESULTS: Four types of lifestyle-relevant challenges to ulcer prevention were identified: risk-elevating life circumstances, communication difficulties, equipment problems, and individual personality issues. Intervention flexibility was achieved by changing the order of treatment modules, altering the intervention content or delivery approach, or going beyond the stipulated content.
CONCLUSION: Attention to recurrent types of individual needs, along with explicit strategies for tailoring interventions published in a manual, has the potential to enhance PrU prevention efforts for adults with SCI.

PURPOSE: The aim of this article is to identify overarching principles that explain how daily lifestyle considerations affect pressure ulcer development as perceived by adults with spinal cord injury (SCI).
METHOD: Qualitative in-depth interviews over an 18-month period with 20 adults with spinal injury and a history of pressure ulcers were conducted using narrative and thematic analyses.
RESULTS: Eight complexly interrelated daily lifestyle principles that explain pressure ulcer development were identified: perpetual danger; change/disruption of routine; decay of prevention behaviors; lifestyle risk ratio; individualization; simultaneous presence of prevention awareness and motivation; lifestyle trade-off; and access to needed care, services and supports.
CONCLUSIONS: Principles pertaining to the relationship between in-context lifestyle and pressure ulcer risk underscore previous quantitative findings, but also lead to new understandings of how risk unfolds in everyday life situations. Pressure ulcer prevention for community-dwelling adults with SCI can potentially be enhanced by incorporating principles, such as the decay of prevention behaviors or lifestyle trade-off, that highlight special patterns indicative of elevated risk. The identified principles can be used to theoretically drive future research or to guide innovative lifestyle-focused intervention approaches. Public policies that promote short-term preventive interventions at critical junctures throughout a person's life should be considered.

(2010). Parasympathetic functions in children with sensory processing disorder. Frontiers in Integrative Neuroscience, 4(4), http://dx.doi.org/10.3389/fnint.2010.00004. Link to full text Abstract →
The overall goal of this study was to determine if parasympathetic nervous system (PsNS) activity is a significant biomarker of sensory processing difficulties in children. Several studies have demonstrated that PsNS activity is an important regulator of reactivity in children, and thus, it is of interest to study whether PsNS activity is related to sensory reactivity in children who have a type of condition associated with sensory processing disorders termed sensory modulation dysfunction (SMD). If so, this will have important implications for understanding the mechanisms underlying sensory processing problems of children and for developing intervention strategies to address them. The primary aims of this project were: (1) to evaluate PsNS activity in children with SMD compared to typically developing (TYP) children, and (2) to determine if PsNS activity is a significant predictor of sensory behaviors and adaptive functions among children with SMD. We examine PsNS activity during the Sensory Challenge Protocol; which includes baseline, the administration of eight sequential stimuli in five sensory domains, recovery, and also evaluate response to a prolonged auditory stimulus. As a secondary aim we examined whether subgroups of children with specific physiological and behavioral sensory reactivity profiles can be identified. Results indicate that as a total group the children with severe SMD demonstrated a trend for low baseline PsNS activity, compared to TYP children, suggesting this may be a biomarker for SMD. In addition, children with SMD as a total group demonstrated significantly poorer adaptive behavior in the communication and daily living subdomains and in the overall Adaptive Behavior Composite of the Vineland than TYP children. Using latent class analysis, the subjects were grouped by severity and the severe SMD group had significantly lower PsNS activity at baseline, tones and prolonged auditory. These results provide preliminary evidence that children who demonstrate severe SMD may have physiological activity that is different from children without SMD, and that these physiological and behavioral manifestations of SMD may affect a child's ability to engage in everyday social, communication, and daily living skills.

Individuals with spinal cord injury (SCI) use wheelchairs for mobility and for full participation in their daily activities. The use of wheelchairs, however, can increase the risk of pressure ulcers. This study focused on wheelchair users’ perceptions of the interplay between their wheeled mobility and the development of pressure ulcers by performing a secondary analysis of data gathered during a 2-year ethnographic study of 20 community-dwelling adults with SCI. Data from a subset of these individuals are described; each of these stories contains a pressure ulcer risk episode related to wheeled mobility or cushion use. Identified risk episodes were associated with wheelchair selection, wheelchair adjustment, habituation to new equipment, lifestyle choices, and challenging life contexts. Examples highlighted the crucial relationship between individuals’ minute-to-minute decision-making and pressure ulcer risk.

Creativity is widely recognized as a powerful and enriching element of people’s lives. However, the actual experience of creativity is seldom described in occupational science or occupational therapy literature. This research paper focuses on the presence of creativity as a process-oriented, intrinsically motivated activity in the lives of 22 individuals. The study included three methods of data collection: Daily Occupational Experience Survey (DOES), intensive interviews, and participant observations. The participants in this study described the experience of creativity as occurring often during their daily occupations, not only during the performance of primary and secondary or enfolded occupations but also while engaging in extraordinary occupations, when the experience of creating was identified a spiritual or transcendental experience. The three themes that emerged from the data are creativity as a process-oriented experience occurring during the performance of daily occupations, the experience of creativity occurring during primary and secondary occupations, and the manifestation of creativity as a transcendental process. This last type of creative expression often served the purpose of selfactualization.
During the past century, numerous researchers and theorists have argued that human lives are largely shaped by the nonreflective realm of habit. Beyond this observation, however, scholarly conceptualizations of habit are widely divergent, ranging from neural-level to culturally saturated macro-level constructs. To clarify the multiple ways that habit has been construed and is related to rehabilitation, the authors present a typology of nine categories of habits: habit as tic; habit as neural networks; habit as conditioned responses; habit as addiction; habit as single, everyday activities; habit as routine; habit as custom, ritual, rite, or ceremony; habit as character; and habit as habitus. Although these categories overlap and share common properties, their conceptual features differ along several dimensions. Each category offers a distinct perspective from which to understand the role of habit in the lives of clients undergoing rehabilitation, which the authors illustrate using examples from the Pressure Ulcer Prevention Study (PUPS), a qualitative study on the contextual factors that lead to serious recurrent pressure ulcers in people with spinal cord injuries. The authors argue that habit is a ubiquitous, protean force that presents itself in many interlinking forms, steering the course of human lives in both health-promoting and destructive directions. To have the greatest effect on health and participation, rehabilitation professionals must examine the nuanced ways that habit may operate both in the lives of clients and in professional practice.

This paper explores the interaction between the philosophy of occupational therapy, the science of occupation and the regional ideology of a specific geographical area, and proposes two models to depict the relationship. One model focuses on the interaction between daily occupational therapy practice in a specific geographical region and the international influences on that practice. The international influences include the effect of occupational science. The second model focuses on the relationship between the philosophy of occupational therapy, occupational science and regional ideology. It concludes by showing the importance of developing a global identity through the importation of knowledge from evolving sciences in industrialized countries at the same time as basic and applied knowledge is developed in the scientific community of a geographic region.
This article raises questions about the ways culture affects the nature of health care services. By examining the life story of Alma, a Central American woman who has a daughter with disabilities; her interactions with health care providers; and my own assumptions about cultural differences, I note the impact of cultural differences on coping and adaptation in Alma and in the health care system when working with poor, non-English-speaking clients.
