Effects and feasibility of virtual reality system vs traditional physical therapy training in multiple sclerosis patients

Abstract

Background/Aims: Traditionally, physical therapy for gait and balance training takes place in a gym setting, which may not fully reproduce situations in everyday activities. The Computer Assisted Rehabilitation ENvironment system provides an immersive virtual environment, allowing a simulation of complex conditions conducive to gait and balance training. The purpose of this study was to determine: (1) the feasibility and safety of using the Computer Assisted Rehabilitation ENvironment system for physical therapy sessions with multiple sclerosis patients, and (2) pre-post treatment changes observed with the Computer Assisted Rehabilitation ENvironment system compared to traditional physical therapy. Findings: Data from functional outcome measures Berg Balance Scale, Timed Up and Go test, Timed 25-Foot Walk, and 6-Minute Walk Test were extracted from the medical records of 62 patients with multiple sclerosis who had at least three physical therapy sessions in either environment. Statistically significant within-group improvements were observed for all outcome measures in the physical therapy Computer Assisted Rehabilitation ENvironment system group (P<0.05), and only for Berg Balance Scale in the traditional physical therapy group. There was a significant between-group difference in favour of physical therapy with the Computer Assisted Rehabilitation ENvironment system for the Timed 25-Foot Walk (P=0.022). Conclusions: The results suggest the Computer Assisted Rehabilitation ENvironment system is a safe and effective tool for physical therapy-led gait and balance training for individuals with multiple sclerosis.
