Self-directed exercise in multiple sclerosis: Evaluation of a home automated tele-management system

Introduction: Physical rehabilitation is one of the few non-pharmaceutical therapies for maintaining or improving walking ability for patients with multiple sclerosis. However, travel distance to rehabilitation clinics, neurological disability and insurance coverage often limit access to specialised rehabilitation services. To address these issues, we utilised a web-based system to support a home-based self-directed exercise programme. Methods: Patients (n = 24) were randomised to either routine home rehabilitation or to the multiple sclerosis home automated tele-management system for a six-month period. The study group had a mean age of 50.4 years, 56% of patients were male, and 67% had progressive multiple sclerosis with an overall mean Patient Determined Disease Steps score of 4.4 (cane or crutch required for walking). Key outcomes included the timed 25-foot-walk, six-minute-walk and the Berg Balance Scale. Results: There was no statistically significant difference in the change of the primary walking outcome measure, timed 25-foot-walk, at six months between the home automated tele-management intervention and control groups (p = 044). Similarly, change scores for the six-minute-walk were not significantly different between the home automated tele-management or control groups at six months. Discussion: Maintaining overall gait abilities in this group of predominantly progressive multiple sclerosis patients is notable. Exercise adherence was positively associated with higher multiple sclerosis disability and self-reported walking ability. Study engagement and participation in routine home-based exercise for the entire study period was challenging. Further research using clinical video telerehabilitation techniques that optimise patient involvement warrants further study.
