BACKGROUND The accessibility, low cost and motivation generated by exergames has fostered its rapid expansion as a rehabilitation technique. OBJECTIVE To estimate the effectiveness of rehabilitation programs using IVGT in improving walking capacity of people aged 60 years and over. MATERIALS AND METHODS The electronic data research following the PRISMA Statement (Scopus, Cochrane, Web of Science, OT Seeker, National Guideline Clearinghouse, Trip Database, CSIC Spanish National Research Council) was completed in September 2018. The results of randomized clinical trials using exergames for rehabilitation of walking capacity were combined. The calculations have followed the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. The Grading of Recommendations Assessment, Development and Evaluation system was used to evaluate the quality of the evidence. RESULTS We obtained data from 14 trials, including 11 meta-analysis studies. The size of exergames effects on walking capacity is moderate, but significant (SMD -0.56; 95 % CI: -0.90, -0.21; p = 0.002). Effectiveness was greater to recover the ability to transfer from one position or place to another (SMD -1.02; CI 95 %: -1.70, -0.35; P = 0.003). The intervention protocols, their duration and intensity varied considerably. The lack of masking, the allocation concealment, the absence of assessor blinding were the main causes of bias so the final grade of evidence has been low for walking and very low for transfers. CONCLUSIONS Positive clinical effects of exergames have been found to improve walking capacity, but the quality of evidence to refute its effectiveness is weak with risk of bias. Further research is needed in order to know the actual magnitude of its effect.

Exergames 能否有助于提高老年人的步行能力？系统评价和元分析

背景技术运动游戏产生的可访问性、低成本和动机促进了其作为一种康复技术的快速扩展。目的 评估使用 IVGT 的康复计划在提高 60 岁及以上人群步行能力方面的有效性。材料和方法 PRISMA 声明（Scopus、Cochrane、Web of Science、OT Seeker、国家指南信息交换所、Trip Database、CSIC 西班牙国家研究委员会）之后的电子数据研究于 2018 年 9 月完成。使用 exergames 的随机临床试验结果用于步行能力的康复相结合。计算遵循 Cochrane 干预措施系统评价手册的指导方针。建议分级评估，开发和评估系统用于评估证据的质量。结果 我们从 14 项试验中获得了数据，包括 11 项荟萃分析研究。运动游戏对步行能力的影响大小适中，但很显着（SMD -0.56；95% CI：-0.90，-0.21；p = 0.002）。恢复从一个位置或位置转移到另一个位置的能力的有效性更高（SMD -1.02；CI 95 %：-1.70，-0.35；P = 0.003）。干预方案、其持续时间和强度差异很大。缺乏掩蔽、分配隐藏、评估员不设盲是导致偏倚的主要原因，因此最终证据等级对于步行来说很低，而对于转移来说非常低。结论 已发现运动游戏的积极临床效果可提高步行能力，但反驳其有效性的证据质量较弱，存在偏倚风险。需要进一步研究以了解其影响的实际大小。
