one-third of community-dwelling older adults fall annually. Exercise that challenges balance is proven to prevent falls. We conducted a systematic review with meta-analysis to determine the impact of yoga-based exercise on balance and physical mobility in people aged 60+ years.
searches for relevant trials were conducted on the following electronic databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, Allied and Complementary Medicine Database and the Physiotherapy Evidence Database (PEDro) from inception to February 2015. Trials were included if they evaluated the effect of physical yoga (excluding meditation and breathing exercises alone) on balance in people aged 60+ years. We extracted data on balance and the secondary outcome of physical mobility. Standardised mean differences and 95% confidence intervals (CI) were calculated using random-effects models. Methodological quality of trials was assessed using the 10-point Physiotherapy Evidence Database (PEDro) Scale.
six trials of relatively high methodological quality, totalling 307 participants, were identified and had data that could be included in a meta-analysis. Overall, yoga interventions had a small effect on balance performance (Hedges' g = 0.40, 95% CI 0.15-0.65, 6 trials) and a medium effect on physical mobility (Hedges' g = 0.50, 95% CI 0.06-0.95, 3 trials).
yoga interventions resulted in small improvements in balance and medium improvements in physical mobility in people aged 60+ years. Further research is required to determine whether yoga-related improvements in balance and mobility translate to prevention of falls in older people. PROSPERO Registration number CRD42015015872.
每年有三分之一的社区老年居民会跌倒。事实证明，挑战平衡能力的运动可预防跌倒。我们进行了一项系统评价和荟萃分析，以确定基于瑜伽的运动对60岁及以上人群平衡能力和身体活动能力的影响。
在以下电子数据库中检索相关试验：MEDLINE、EMBASE、Cochrane对照试验中央注册库、CINAHL、联合与补充医学数据库以及理疗证据数据库（PEDro），检索时间从建库至2015年2月。如果试验评估了身体瑜伽（不包括单独的冥想和呼吸练习）对60岁及以上人群平衡能力的影响，则纳入该试验。我们提取了平衡能力和身体活动能力这一次要结局的数据。使用随机效应模型计算标准化均数差和95%置信区间（CI）。使用10分制的理疗证据数据库（PEDro）量表评估试验的方法学质量。
确定了6项方法学质量相对较高的试验，共有307名参与者，其数据可纳入荟萃分析。总体而言，瑜伽干预对平衡能力表现有较小影响（Hedges' g = 0.40，95% CI 0.15 - 0.65，6项试验），对身体活动能力有中等影响（Hedges' g = 0.50，95% CI 0.06 - 0.95，3项试验）。
瑜伽干预使60岁及以上人群的平衡能力有小幅改善，身体活动能力有中等程度改善。需要进一步研究以确定与瑜伽相关的平衡能力和活动能力改善是否能转化为预防老年人跌倒。国际前瞻性系统评价注册库登记号CRD42015015872。
