目的：评价太极拳组合与家庭训练对老年膝关节骨性关节炎的治疗效果。设计：随机、对照、单盲试验，按年龄和性别分层，为期12周，随访6周。设置：普通社区。参与者：41名患有膝骨关节炎的成年人（70±9.2岁）。干预措施：太极项目的特点是六周的集体太极课程，每次40分钟，每周三次，然后是另外六周（第7-12周）的家庭太极训练。受试者被要求在6周的随访去训练期（13-18周）停止太极拳训练。注意控制组的受试者按照与以小组为基础的太极干预（0-6周）相同的时间表参加了六周的健康讲座，随后是12周的无活动（7-18周）。主要结果测量：在18周的研究期间，在基线和每三周记录一次用视觉模拟量表测量的膝关节疼痛，用西安大略省和麦克马斯特大学骨关节炎指数（WOMAC）测量的膝关节运动范围和身体功能。数据分析采用混合模型方差分析。结果：与基线相比，6周的团体太极训练和另外6周的家庭太极训练显示，平均总体膝关节疼痛（P = 0.0078），最大膝关节疼痛（P = 0.0035）和WOMAC身体功能亚量表（P = 0.0075）和僵硬（P = 0.0206）显著改善。在整个研究过程中，注意控制组没有注意到任何结果测量的显著变化。在第9周和第12周，与注意力对照组相比，太极拳组的整体疼痛程度更低，WOMAC身体功能更好。去训练后，所有的改善都消失了。结论：团体和家庭太极项目对老年膝关节骨性关节炎患者的膝关节疼痛减轻和身体功能改善有显著作用。这些效果在去训练后没有持续。
Objective: To evaluate the effects of tai chi consisting of group and home-based sessions in elderly subjects with knee osteoarthritis.Design: A randomized, controlled, single-blinded 12-week trial with stratification by age and sex, and six weeks of follow-up.Setting: General community.Participants: Forty-one adults (70 +/- 9.2 years) with knee osteoarthritis.Interventions: The tai chi programme featured six weeks of group tai chi sessions, 40 min/session, three times a week, followed by another six weeks (weeks 7-12) of home-based tai chi training. Subjects were requested to discontinue tai chi training during a six-week follow-up detraining period (weeks 13-18). Subjects in the attention control group attended six weeks of health lectures following the same schedule as the group-based tai chi intervention (weeks 0-6), followed by 12 weeks of no activity (weeks 7-18).Main outcome measures: Knee pain measured by visual analogue scale, knee range of motion and physical function measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were recorded at baseline and every three weeks throughout the 18-week study period. Data were analysed using a mixed model ANOVA.Results: The six weeks of group tai chi followed by another six weeks of home tai chi training showed significant improvements in mean overall knee pain (P = 0.0078), maximum knee pain (P = 0.0035) and the WOMAC subscales of physical function (P = 0.0075) and stiffness (P = 0.0206) compared to the baseline. No significant change of any outcome measure was noted in the attention control group throughout the study. The tai chi group reported lower overall pain and better WOMAC physical function than the attention control group at weeks 9 and 12. All improvements disappeared after detraining.Conclusions: The group and home based tai chi programme provided significant knee pain reduction and physical function improvement in elderly subjects with knee osteoarthritis. These effects were not sustained after detraining.
