To examine the effects of a 12-week therapeutic yoga program on gait speed, postural control, and mobility in community-dwelling older adults.
Quasi-experimental study with a pretest/post-test design. Researchers evaluated changes over time (pretest to post-test) in all outcome measures. Paired t-tests were used to analyze normal and fast gait speed, Timed Up and Go test, and Timed Up and Go Dual Task. Wilcoxon signed-rank test was used to evaluate scores for the Mini-BESTest (MBT).
Yoga classes were performed at a local senior center. Blind examiners who were previously trained in the outcome measures performed all pretests and post-tests at the site.
Thirteen adults (12 women and 1 man, with a mean age±standard deviation of 72±6.9 years) completed the study. Research participants had minimal to no yoga experience.
A 12-week, 60-minute, biweekly Kripalu yoga class designed specifically for community-dwelling older adults.
Postural control (MBT), mobility (Timed Up and Go test), and gait speed (normal and fast) were assessed.
All 13 participants attended at least 19 of the 24 classes (80% attendance). Statistically significant improvements were seen in the MBT (p=0.039), normal gait speed (p=0.015), fast gait speed (p=0.001), Timed Up and Go test (p=0.045), and Timed Up and Go Dual-Task (p=0.05).
Improvements in postural control and mobility as measured by the MBT and Timed Up and Go gait as measured by fast gait speed indicate that research participants benefitted from the therapeutic yoga intervention. The yoga program designed for this study included activities in standing, sitting, and lying on the floor and may be effective in improving mobility, postural control, and gait speed in community-dwelling older adults.
探讨为期12周的治疗性瑜伽课程对社区居住的老年人步态速度、姿势控制和活动能力的影响。
采用前测/后测设计的准实验研究。研究人员评估了所有结果指标随时间（从前测到后测）的变化。配对t检验用于分析正常和快速步态速度、计时起立行走测试以及计时起立行走双重任务。Wilcoxon符号秩检验用于评估简短伯格平衡量表（MBT）的得分。
瑜伽课程在当地一家老年中心进行。之前接受过结果指标培训的盲法检查人员在该地点进行了所有前测和后测。
13名成年人（12名女性和1名男性，平均年龄±标准差为72±6.9岁）完成了该研究。研究参与者几乎没有或没有瑜伽经验。
为期12周、每周60分钟、每两周一次的专为社区居住的老年人设计的克里帕鲁瑜伽课程。
评估姿势控制（MBT）、活动能力（计时起立行走测试）和步态速度（正常和快速）。
13名参与者全部参加了24节课中的至少19节（出勤率80%）。在MBT（p = 0.039）、正常步态速度（p = 0.015）、快速步态速度（p = 0.001）、计时起立行走测试（p = 0.045）和计时起立行走双重任务（p = 0.05）方面观察到了具有统计学意义的改善。
通过MBT测量的姿势控制和通过快速步态速度测量的计时起立行走步态的改善表明，研究参与者从治疗性瑜伽干预中受益。为本研究设计的瑜伽课程包括站立、坐立和躺在地板上的活动，可能对改善社区居住的老年人的活动能力、姿势控制和步态速度有效。
