Research Interests

I am a licensed and registered occupational therapist and PhD candidate in the USC Chan Division of Occupational Science and Occupational Therapy. Within the MSOP lab, I act as a research assistant on the currently funded R01 grant which is investigating carpal tunnel syndrome within the dental hygiene profession. Also, I have assisted in coordinating the recently completed mind-body hand therapy study which piloted mindfulness and biofeedback interventions in hand therapy. My research interests span the treatment of musculoskeletal disorders, mind-body interventions for occupational therapy, and motivational psychology.

Roll, S. C., & Hardison, M. E. (2017). Effectiveness of occupational therapy interventions for adults with musculoskeletal conditions of the forearm, wrist, and hand: A systematic review. American Journal of Occupational Therapy, 71(1), 7101180010p1-7101180010p12. Show abstractHide abstract

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.

A scoping review was conducted to describe how mindfulness is used in physical rehabilitation, identify implications for occupational therapy practice, and guide future research on clinical mindfulness interventions. A systematic search of four literature databases produced 1,524 original abstracts, of which 16 articles were included. Although only 3 Level I or II studies were identified, the literature included suggests that mindfulness interventions are helpful for patients with musculoskeletal and chronic pain disorders and demonstrate trends toward outcome improvements for patients with neurocognitive and neuromotor disorders. Only 2 studies included an occupational therapist as the primary mindfulness provider, but all mindfulness interventions in the selected studies fit within the occupational therapy scope of practice according to the American Occupational Therapy Association's Occupational Therapy Practice Framework: Domain and Process. Higher-level research is needed to evaluate the effects of mindfulness interventions in physical rehabilitation and to determine best practices for the use of mindfulness by occupational therapy practitioners.

Risk assessment for musculoskeletal strain among dental hygienists: Validity and reliability of a video observation technique [Presentation at the 2018 AOTA Annual Conference & Expo, Salt Lake City, UT].

Upper extremity musculoskeletal injuries are common in dental hygienists. To enhance prevention, an ecologically valid observational technique for evaluating risks in dental hygiene practice is needed. This study describes a new video observation technique and reliability results.

Hardison, M., Black, D., & Roll, S. C. (2018). Effects of mind–body interventions on stress, anxiety, and pain in hand therapy patients [Presentation at the 2018 AOTA Annual Conference & Expo, Salt Lake City, UT]. American Journal of Occupational Therapy, 72(4, Suppl. 1), 7211515280p1. Show abstractHide abstract

This randomized, crossover pilot study explored the acute effects of mindfulness and visual biofeedback on pain, stress, and anxiety in hand therapy. Reduction in anxiety and trending reduction in stress within the experimental conditions indicate that a future, fully powered trial is warranted.

Hardison, M., & Roll, S. C. (2016). Mindfulness for physical rehabilitation in occupational therapy: A scoping review [Poster presented at the 2016 AOTA Annual Conference & Expo, Chicago, IL]. American Journal of Occupational Therapy, 70(4, Suppl. 1), 7011505137p1. Show abstractHide abstract

This scoping review describes how mindfulness interventions are being used for rehabilitation of physical disorders. Mindfulness interventions fit within the scope of occupational therapy for physical disorders, but there is a dearth of research translating this to practice-based settings.
