It remains unclear whether Tai Chi is effective for walking function and posture control improvements in aged populations with knee osteoarthritis. The aim of this study was to systematically evaluate the effects of Tai Chi on improving walking function and posture control in elderly patients with knee osteoarthritis by updating the latest trial evidence.
Web of Science, PubMed/Medline, Embase, Scopus, PEDro, and Cochrane library were searched up to October 1, 2020 to identify RCTs evaluating Tai Chi for improving walking function and posture control in older adults with knee osteoarthritis. The primary outcomes were walking function and posture control. Meta-analysis was performed with RevMan Version 5.3 software.
A total of 603 participants with knee osteoarthritis in the 11 trials were included. The results of meta-analysis showed that: The Tai Chi group was associated with better performance in 6-minute walk test (6 MWT), time up and go test (TUG) and "Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index" Physical Function Score than the control group ([MD: 46.67, 95% CI 36.91-56.43, P < .001]), ([MD: -0.89, 95% CI -1.16 to -0.61, P < .001]), ([MD: -11.28, 95% CI -13.33 to -9.24, P < .001]).
This meta-analysis provided evidence from 11 RCTs that Tai Chi could be an excellent physical training strategy for improving walking function and posture control in older adults with knee osteoarthritis. Assuming that Tai Chi is at least effective and safe in most areas, it can be used as an adjuvant and reliable physical training strategy for walking function upgrading and balance control improvements for older patients with knee osteoarthritis.
目前尚不清楚太极拳是否对改善膝骨关节炎老年人群的步行功能和姿势控制有效。本研究旨在通过更新最新的试验证据，系统评价太极拳对改善膝骨关节炎老年患者步行功能和姿势控制的影响。
截至 2020 年 10 月 1 日，我们在 Web of Science、PubMed/Medline、Embase、Scopus、PEDro 和 Cochrane 图书馆中检索了评估太极拳改善老年膝骨关节炎患者步行功能和姿势控制的随机对照试验（RCT）。主要结局为步行功能和姿势控制。采用 RevMan Version 5.3 软件进行荟萃分析。
共有 11 项试验的 603 例膝骨关节炎患者纳入本研究。荟萃分析结果显示：太极拳组在 6 分钟步行试验（6 MWT）、起立行走试验（TUG）和“西安大略和麦克马斯特大学骨关节炎指数”（WOMAC）身体功能评分方面的表现优于对照组[MD：46.67，95% CI 36.91-56.43，P<0.001]，[MD：-0.89，95% CI -1.16 至-0.61，P<0.001]，[MD：-11.28，95% CI -13.33 至-9.24，P<0.001]。
这项荟萃分析提供了 11 项 RCT 的证据，表明太极拳可能是改善膝骨关节炎老年患者步行功能和姿势控制的一种极好的身体训练策略。假设太极拳在大多数地区至少是有效和安全的，它可以作为一种辅助和可靠的身体训练策略，用于升级老年膝骨关节炎患者的步行功能和平衡控制。
