摘要
膝关节骨性关节炎（KOA）是一种常见的退行性关节疾病，严重降低老年人的活动能力和生活质量。太极拳是一种低强度的身心运动，被认为是治疗KOA的潜在非药物干预手段，但其生物力学效果尚不清楚。本研究旨在评估为期14周的太极项目对老年KOA患者临床症状、下肢生物力学和肌肉激活模式的影响。进行了一项单盲随机对照试验，招募了24名年龄为55-70岁的单侧KOA患者。参与者被随机分配到太极干预组和只接受健康教育的对照组。主要结果包括关节活动范围、关节力矩和肌肉激活，使用运动捕捉系统和表面肌电图测量。次要结果，如疼痛、僵硬、功能（WOMAC）、平衡（BBS）和生活质量（SF-12），也在干预前和干预后进行评估。与对照组相比，太极组在WOMAC疼痛（-1.58±1.44 vs. 0.11±0.78,p = 0.01）、僵硬度（-0.33±0.78 vs. 0.56±0.88,p = 0.02）和功能评分（-2.58±3.53 vs. 1.00±2.78,p = 0.02）方面均有显著改善。平衡（BBS: 1.42±1.88比-0.89±1.27,p = 0.01）和身体健康（SF-12 PCS: 5.45±6.76比-1.05±2.17,p = 0.01）也有所改善。生物力学方面，太极拳降低膝关节水平平面ROM（-3.03±1.00°，p = 0.01）和最大膝关节伸展力矩（患侧：-0.09±0.04 N/kg, p = 0.04，非患侧：-0.11±0.05 N/kg, p = 0.03）。胫骨前肌激活度明显升高（5.66±1.05%MVIC, p = 0.02），其他肌群无明显变化。太极拳对老年KOA患者具有显著的临床和生物力学益处，表明其作为一种安全、可及和有效的治疗干预手段的潜力。
The effects of Tai Chi on clinical outcomes and gait biomechanics in knee osteoarthritis patients: a pilot randomized controlled trial.
Knee osteoarthritis (KOA) is a common degenerative joint disease that significantly reduces mobility and quality of life in elderly populations. Tai Chi, a low-impact mind-body exercise, has been suggested as a potential non-pharmacological intervention for managing KOA, but its biomechanical effects remain unclear. This study aimed to evaluate the effects of a 14-week Tai Chi program on clinical symptoms, lower limb biomechanics, and muscle activation patterns in elderly patients with KOA. A single-blinded randomized controlled trial was conducted, enrolling 24 participants aged 55-70 years with unilateral KOA. Participants were randomly assigned to a Tai Chi intervention group or a control group receiving health education only. Primary outcomes included joint range of motion, joint moments, and muscle activation, measured using a motion capture system and surface electromyography. Secondary outcomes, such as pain, stiffness, function (WOMAC), balance (BBS), and quality of life (SF-12), were also assessed pre- and post-intervention. The Tai Chi group demonstrated significant improvements in WOMAC pain (-1.58 ± 1.44 vs. 0.11 ± 0.78, p = 0.01), stiffness (-0.33 ± 0.78 vs. 0.56 ± 0.88, p = 0.02), and function scores (-2.58 ± 3.53 vs. 1.00 ± 2.78, p = 0.02) compared to the control group. Balance (BBS: 1.42 ± 1.88 vs. -0.89 ± 1.27, p = 0.01) and physical health (SF-12 PCS: 5.45 ± 6.76 vs. -1.05 ± 2.17, p = 0.01) were also enhanced. Biomechanically, Tai Chi reduced horizontal plane knee ROM (-3.03 ± 1.00°, p = 0.01) and maximum knee extension moments (affected side: -0.09 ± 0.04 N/kg, p = 0.04, Non-affected side: -0.11 ± 0.05 N/kg, p = 0.03). Tibialis anterior muscle activation increased significantly (5.66 ± 1.05%MVIC, p = 0.02), while other muscles showed non-significant trends. Tai Chi demonstrated significant clinical and biomechanical benefits for elderly KOA patients, suggesting its potential as a safe, accessible, and effective therapeutic intervention.
