Background
Though rehabilitation therapy is commonly provided after stroke, many patients do not derive maximal benefit due to access, cost, and compliance. A telerehabilitation-based program may overcome these barriers. We designed then evaluated a home-based telerehabilitation system in patients with chronic hemiparetic stroke.
Methods
Patients were 3–24 months post-stroke with stable arm motor deficits. Each received 28 days of telerehabilitation using a system delivered to their home. Each day consisted of one structured hour focused on individualized exercises and games, stroke education, and an hour of free-play.
Results
Enrollees (n=12) had baseline Fugl-Meyer (FM) score of 39±12 (mean±SD). Compliance was excellent: participants engaged in therapy on 329/336 (97.9%) assigned days. Arm repetitions across the 28 days averaged 24,607±9,934 per subject. Arm motor status showed significant gains (FM change 4.8±3.8 points, p=0.0015), with half of subjects exceeding the minimal clinically important difference. Although scores on tests of computer literacy declined with age (r=−0.92, p<0.0001), neither the motor gains nor the amount of system use varied with computer literacy. Daily stroke education via the telerehabilitation system was associated with a 39% increase in stroke prevention knowledge (p=0.0007). Depression scores obtained in person correlated with scores obtained via the telerehabilitation system 16 days later (r=0.88, p=0.0001). In-person blood pressure values closely matched those obtained via this system (r=0.99, p<0.0001).
Conclusions
This home-based system was effective in providing telerehabilitation, education, and secondary stroke prevention to participants. Use of a computer-based interface offers many opportunities to monitor and improve the health of patients after stroke.
