RESUMEN

In recent years, innovative technologies have gained prominence in stroke patient rehabilitation worldwide, with virtual reality-based mirror therapy (VRBMT) emerging as a notable example. Hence, the present study aims to determine the efficacy of VRBMT on upper extremity motor function, manual performance, and gross manual dexterity among stroke patients. The systematic search utilized Population, Intervention, Comparison, Outcome, and Design (PICOD) paradigm, and the study searched was based on 2012-2023, utilizing different databases. The meta-analysis data was evaluated using MedCalc version 18.11.3. The Pooled effect size mean was statistically examined using a fixed and random effect model. Among the 6 studies selected, 4 studies involving upper-limb stroke patients were identified between the VRBMT. Pooled analysis of VRBMT revealed no significant effect on motor function [standardized mean difference (SMD) 0.815; 95% CI 0.00 to 81.37; P = 0.5562]. The remaining 2 of 6 studies participated in the study of the manual performance stroke patients (SMD 0.869; 95% CI 0.00 to 93.22; P = 0.0684). The pooled analysis of VRBMT revealed no significant effect. The last 2 of 6 included studies on gross manual dexterity in stroke. The pooled analysis also showed no significant effects on VRBMT (SMD 0.198; 95% CI 0.00 to 0.00; P = 0.6951). The present study concluded although VRBMT exhibits potential as a novel method for stroke rehabilitation, its effects on gross manual dexterity, manual performance, and upper extremity motor function are not statistically significant may be due to a limited number of studies on VRBMT in stroke patients.
