Virtual Reality Augments Movement During Physical Therapy

Abstract

Objective: Virtual reality facilitates physical therapy via improved engagement. Although shown to benefit specific patient populations, such as stroke patients, it is less established in otherwise healthy adults and children receiving outpatient physical therapy. The primary objective was to compare total physical therapy-guided movement supplemented with virtual reality with physical therapy-guided movement alone without virtual reality. Design: This pragmatic, randomized, crossover study compared physical therapy-guided movement supplemented with virtual reality with physical therapy-guided movement alone without virtual reality in outpatients (ages 6-80 yrs). This community sample had variable physical therapy indications (injury, postoperative, chronic pain), and in pre-existing conditions, therefore, participants served as their own controls. Participants received 10 mins of both physical therapy-guided movement supplemented with virtual reality and physical therapyguided movement alone without virtual reality separated by 5 mins. The primary outcome was differences in aggregate movement of physical therapy-guided exercises. Secondary outcomes explored OMNI rating of perceived exertion and participant and physical therapist satisfaction. Paired t tests, χ 2 tests, and regression models were used to analyze differences. Results: The 41 participants (17 pediatric and 24 adult) moved significantly more during physical therapy-guided movement supplemented with virtual reality compared with physical therapy-guided movement alone without virtual reality (1120.88 vs. 672.65 m, P < 0.001), regardless of which intervention was completed first. Physical therapy-guided movement supplemented with virtual reality treatment was associated with more movement of the target limbs, lower body (P < 0.001), and upper body (P < 0.05). The OMNI rating of perceived exertion scores did not differ between those who started with physical therapy-guided movement supplemented with virtual reality or physical therapy-guided movement alone without virtual reality, and physical therapist and patient surveys endorsed physical therapy-guided movement supplemented with virtual reality. Conclusions: Patients completed more physical therapy-guided movement during physical therapy-guided movement supplemented with virtual reality than physical therapy-guided movement alone without virtual reality, and therapists and patients supported its use. Future studies will examine finer tracking of movements.

Centering Patient and Clinician Voices in Developing Tools to Address Pain Related School Impairment: A Phase I Study of a Virtual Reality School Simulation for Children and Adolescents with Chronic Pain

“…To date, the application of VR in pediatric chronic pain rehabilitation has been largely limited to the physical therapy context, with increasing movement being the main treatment target [16,17]. VR has untapped potential to address more holistic, integrative functional goals such as the return to school, a goal that crosses the disciplinary boundaries of physical, occupational, and psychological treatments.…”
