尽管太极拳已被证明可以缓解膝关节骨关节炎（OA）患者的疼痛并改善功能活动性，但对于影像学和症状性膝关节OA患病率较高的中国老年女性的步态特征，其潜在益处知之甚少。本研究旨在评估量身定制的太极拳干预对中国老年膝关节骨性关节炎女性步态运动学的有效性。一项随机对照试验，涉及中国上海46名临床诊断为膝关节OA的老年女性。随机（1：1）的参与者接受每周3次60分钟的太极拳课程（n = 23）或每两周60分钟的教育课程（n = 23），持续24周。主要结局是步态运动学指标从基线到24周的变化。次要结局包括西安大略和麦克马斯特大学骨关节炎指数（WOMAC）和短期体能测试（SPPB）评分的变化。24周后，太极拳组在步态速度方面表现出更好的表现（平均差异，8.40 cm/s，p = 0.01），步长（平均差，3.52 cm，p = 0.004），初始接触角（平均差异，2.19°，p = 0.01）和最大角度（平均差异，2.61°，p = 0.003）。此外，太极拳组在WOMAC评分（p < 0.01）（平均差异，疼痛为-4.22分，p = 0.002;僵硬为-2.41分，p < 0.001;身体功能为-11.04分，p = 0.006）和SPPB评分（平均差异，1.22分，p < 0.001）方面表现出显著改善。在患有膝关节OA的中国老年女性中，量身定制的太极拳干预改善了步态结果。根据WOMAC和SPPB指数，干预还改善了整体功能。这些结果支持太极拳用于患有膝关节OA的中国老年人，以改善其功能活动性并减少疼痛。
Although Tai Ji Quan has been shown to relieve pain and improve functional mobility in people with knee osteoarthritis (OA), little is known about its potential benefits on gait characteristics among older Chinese women who have a high prevalence of both radiographic and symptomatic knee OA. This study aims to assess the efficacy of a tailored Tai Ji Quan intervention on gait kinematics for older Chinese women with knee OA. A randomized controlled trial involving 46 older women in Shanghai, China, with clinically diagnosed knee OA. Randomized (1:1) participants received either a 60 min Tai Ji Quan session (n = 23) 3 times weekly or a 60 min bi-weekly educational session (n = 23) for 24 weeks. Primary outcomes were changes in gait kinematic measures from baseline to 24 weeks. Secondary outcomes included changes in scores on the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Short Physical Performance Battery (SPPB). After 24 weeks the Tai Ji Quan group demonstrated better performance in gait velocity (mean difference, 8.40 cm/s, p = 0.01), step length (mean difference, 3.52 cm, p = 0.004), initial contact angle (mean difference, 2.19°, p = 0.01), and maximal angle (mean difference, 2.61°, p = 0.003) of flexed knees during stance phase compared to the control group. In addition, the Tai Ji Quan group showed significant improvement in WOMAC scores (p < 0.01) (mean difference, −4.22 points in pain, p = 0.002; −2.41 points in stiffness, p < 0.001; −11.04 points in physical function, p = 0.006) and SPPB scores (mean difference, 1.22 points, p < 0.001). Among older Chinese women with knee OA, a tailored Tai Ji Quan intervention improved gait outcomes. The intervention also improved overall function as indexed by the WOMAC and SPPB. These results support the use of Tai Ji Quan for older Chinese adults with knee OA to both improve their functional mobility and reduce pain symptomatology.
