Abstract
OBJECTIVE: The study aimed to evaluate the effect of virtual reality on balance, motor function, gait, and the ability to perform activities of daily living in patients with Parkinson disease. METHODS: We searched Cochran Central Register of Controlled Trials, Embase, PubMed, Wanfang Data, VIP Database, and China National Knowledge Infrastructure from their inception to June 2019. Two authors independently screened articles for inclusion, extracted data, and evaluated quality. RESULTS: Twelve randomized clinical trials involving 360 patients were included. It demonstrated that virtual reality can improve balance, measured by the Berg Balance Scale (fixed model weighted mean difference = 2.28, 95% CI = 1.39 to 3.16, P < 0.00001); strengthen motor function, assessed by the Timed Up and Go test (fixed model weighted mean difference = -1.66, 95% CI = -2.74 to 0.58, P = 0.003); enhance gait ability, assessed by the 10-Meter Walk Test Time (fixed model weighted mean difference = 0.13, 95% CI = 0.02 to 0.24, P = 0.02) in patients with Parkinson disease. It also showed that virtual reality can improve individuals' ability to perform activities of daily living, assessed by modified Barthel Index (fixed model weighted mean difference = 2.93, 95% CI = 0.8 to 5.06, P = 0.007). CONCLUSIONS: The findings suggest that virtual reality rehabilitation may be valuable in improving the balance, motor function, gait, and ability to perform activities of daily living in patients with Parkinson disease.
