The purpose of this study is to analyze the biomechanics of ankle cartilage and ligaments during a typical Tai Chi movement-Brush Knee and Twist Step (BKTS). The kinematic and kinetic data were acquired in one experienced male Tai Chi practitioner while performing BKTS and in normal walking. The measured parameters were used as loading and boundary conditions for further finite element analysis. This study showed that the contact stress of the ankle joint during BKTS was generally less than that during walking. However, the maximum tensile force of the anterior talofibular ligament, the calcaneofibular ligament and the posterior talofibular ligament during BKTS was 130 N, 169 N and 89 N, respectively, while it was only 57 N, 119 N and 48 N during walking. Therefore, patients with arthritis of the ankle can properly practice Tai Chi. Practitioners with sprained lateral ligaments of the ankle joint were suggested to properly reduce the ankle movement range during BKTS.
本研究的目的是分析在典型太极拳动作——搂膝拗步（BKTS）过程中踝关节软骨和韧带的生物力学。在一名经验丰富的男性太极拳练习者进行BKTS以及正常行走时采集了运动学和动力学数据。所测量的参数被用作进一步有限元分析的载荷和边界条件。本研究表明，BKTS过程中踝关节的接触应力总体上小于行走过程中的接触应力。然而，BKTS过程中距腓前韧带、跟腓韧带和距腓后韧带的最大拉力分别为130 N、169 N和89 N，而行走过程中分别仅为57 N、119 N和48 N。因此，踝关节关节炎患者可以适当练习太极拳。建议踝关节外侧韧带扭伤的练习者在BKTS过程中适当减小踝关节的活动范围。
