The objective of this study was to systematically review the effect of virtual reality on balance as compared to conventional therapy alone poststroke.
The databases of PubMed, Cochrane, and Ovid were searched using select keywords. The randomized controlled trials published between January 2000 and August 2017 in English language were included if they assessed the effect of virtual reality on balance ability compared to conventional therapy alone in adults' poststroke. The Physiotherapy Evidence Database scale was used to assess the methodological quality.
Fourteen papers were included in this review. The experimental groups largely (n = 13) used virtual reality in combination with conventional therapy. Among the high quality studies, significant between-group improvement favoring virtual reality in combination with conventional therapy was found on Berg Balance Scale (n = 7) and Timed Up and Go Scale (n = 7) when compared to conventional therapy alone. The studies were limited by low powered, small sample sizes ranging from 14 to 40, and lack of blinding, concealed allocation, and reporting of missing data. Thirteen homogenous (n = 348, I = 37.6%, P = .083) studies were included in the meta-analysis using Berg Balance Scale. Significant improvement was observed in the experimental group compared to control group with a medium effect size of .64, confidence interval of .36-.92.
The findings of this review indicate that virtual reality when combined with conventional therapy is moderately more effective in improving balance than conventional therapy alone in individuals' poststroke.
本研究的目的是系统评价与单纯传统疗法相比，虚拟现实对中风后平衡能力的影响。
使用选定的关键词检索PubMed、Cochrane和Ovid数据库。纳入2000年1月至2017年8月发表的英文随机对照试验，这些试验评估了与单纯传统疗法相比，虚拟现实对成人中风后平衡能力的影响。使用物理治疗证据数据库量表评估方法学质量。
本综述纳入了14篇论文。实验组大多（n = 13）将虚拟现实与传统疗法联合使用。在高质量研究中，与单纯传统疗法相比，在Berg平衡量表（n = 7）和计时起立行走量表（n = 7）上发现联合虚拟现实与传统疗法的组间改善具有显著差异。这些研究存在局限性，包括功效低、样本量小（14至40例），以及缺乏盲法、隐蔽分配和缺失数据报告。使用Berg平衡量表的荟萃分析纳入了13项同质研究（n = 348，I = 37.6%，P = 0.083）。与对照组相比，实验组观察到显著改善，中等效应大小为0.64，置信区间为0.36 - 0.92。
本综述结果表明，在中风患者中，虚拟现实与传统疗法联合使用在改善平衡方面比单纯传统疗法适度更有效。
