Journal CME, March 2022: Home-based Virtual Reality Therapy for Hand Recovery after Stroke-Home-based Virtual Reality Therapy

Home-based Virtual Reality Therapy - Article.pdf

Pdf Summary

The study investigates the feasibility and efficacy of a home-based, unsupervised virtual reality device (Smart Glove) for hand rehabilitation in chronic stroke patients. This device aims to mitigate the persistent arm and hand weaknesses that many stroke survivors face, which pose challenges to daily living activities. Conventional treatments like constraint-induced movement therapy and robotic devices have limitations including high costs and patient frustration; thus, alternatives like VR therapy are being explored.<br /><br />In this prospective single-arm study, 20 participants were instructed to use the Smart Glove for 50 minutes daily, five days a week over an 8-week period. Compliance, patient feedback, and effectiveness were evaluated using several metrics: upper extremity Fugl-Meyer (UE-FM), Jebsen-Taylor hand function test (JTHFT), and the Stroke Impact Scale (SIS).<br /><br />Results indicated that 35% of participants met the compliance target, while 30% used the device for 20-39 days. Participants generally found the therapy satisfactory, with 85% reporting improvement in hand function. Statistically significant improvement was observed in the JTHFT, with a mean reduction of 26.6 seconds, and an SIS hand function domain increase by 16.1 points, though UE-FM improvements were not statistically significant.<br /><br />This pilot study suggests that the Smart Glove can enhance hand and arm function in chronic stroke patients. It provides an engaging, user-friendly, and accessible therapeutic option that can supplement traditional therapies. However, for conclusive evidence, a randomized controlled trial is recommended. The study highlights the potential of VR therapy to offer meaningful rehabilitation to those with limited access to formal occupational therapy. <br /><br />Future research should focus on optimizing therapy frequency, understanding long-term benefits, and assessing the device's impact on patients with varying levels of initial impairment. The goal is to offer a practical, enjoyable, and effective therapeutic alternative to improve the quality of life for stroke survivors.
