我们先前的研究表明，6周的太极锻炼显著改善了患有膝骨性关节炎的老年患者的膝关节疼痛和僵硬。本研究还探讨了太极运动对老年膝骨性关节炎患者的步态运动学、身体功能、疼痛和疼痛自我效能的影响。在这项前瞻性、前测-后测的临床试验中，40名被诊断为膝骨性关节炎的男性和女性(64.4+/-8.3岁)参加了为期6周的指导太极训练，1小时/次，每周2次。在基线和干预结束时采取以下措施：(A)通过视频分析量化步态运动学，包括步长、步频和步速，(B)身体功能，(C)膝关节疼痛，(D)疼痛自我效能。数据采用重复的MANCOVA、MANOVA、ANOVA和Wilcoxon检验进行分析。经过6周的太极拳训练，参与者的步长(p=0.023；1.17+/-0.17vs.1.20+/-0.14m)、步频(p=0.014；0.91+/-0.08vs.0.93+/-0.08/S)以及步态速度(p<；0.025；1.06+/-0.19vs.1.12+/-0.15m/S)增加。身体功能明显改善(p<；0.001)，膝关节疼痛明显减轻(p=0.002)，疼痛自我效能感无明显变化。综上所述，这些发现支持太极对老年膝骨性关节炎患者的步态运动学是有益的，需要更长期的应用来证实太极作为一种替代运动在治疗膝骨性关节炎中的效果。
Our previous study has demonstrated that 6 weeks of Tai Chi exercise significantly improves knee pain and stiffness in elderly with knee osteoarthritis. This study also examine the effects of Tai Chi exercise on gait kinematics, physical function, pain, and pain self-efficacy in elderly with knee osteoarthritis. In this prospective, pretest-posttest clinical trial, 40 men and women (64.4 +/- 8.3 years) diagnosed with knee osteoarthritis participated in 6 weeks of instructed Tai Chi training, 1 hour/session, 2 sessions/week. The following measures were taken at baseline and the conclusion of the intervention: (a) gait kinematics including stride length, stride frequency, and gait speed quantified using video analysis, (b) physical function, (c) knee pain, and (d) pain self-efficacy. Data were analyzed using repeated MANCOVA, MANOVA, ANOVA and Wilcoxon tests. After 6 weeks of Tai Chi exercise, stride length (p = 0.023; 1.17 +/- 0.17 vs. 1.20 +/- 0.14 m), stride frequency (p = 0.014; 0.91 +/- 0.08 vs. 0.93 +/- 0.08 strides/s), and consequently gait speed (p < 0.025; 1.06 +/- 0.19 vs. 1.12 +/- 0.15 m/s) increased in the participants. Physical function was significantly improved (p < 0.001) and knee pain was significantly decreased (p = 0.002), while no change was observed in pain self-efficacy. In conclusion, these findings support that Tai Chi is beneficial for gait kinematics in elderly with knee osteoarthritis, and a longer term application is needed to substantiate the effect of Tai Chi as an alternative exercise in management of knee osteoarthritis.
