There is little research related to the biomechanical effects of Tai Chi on the hip joint. This study was aimed to analyze the biomechanical characteristic of a typical Tai Chi movement, Brush Knee and Twist Step. A total of 12 experienced older men voluntarily participated in this study. Each participant was requested to perform standard Brush Knee and Twist Step and normal walking. The scaled-generic musculoskeletal model of each participant was developed. A finite element model of the hip joint and pelvis was established and validated. Data from each trail were input to the model for simulation, and the biomechanics were compared between Brush Knee and Twist Step and walking. Compared with walking, Tai Chi may have better improvement in the range of motion of the hip joint and the coordination of the neuromuscular system under safer condition. It is suitable for patients with hip osteoarthritis and the older adults with severe muscle loss, and clinical studies are required to confirm it further.
关于太极拳对髋关节生物力学影响的研究较少。本研究旨在分析典型太极拳动作“搂膝拗步”的生物力学特征。共有12名经验丰富的老年男性自愿参与本研究。要求每位参与者进行标准的“搂膝拗步”和正常行走。建立了每位参与者的缩放通用肌肉骨骼模型。建立并验证了髋关节和骨盆的有限元模型。将每次试验的数据输入模型进行模拟，并比较“搂膝拗步”、正常行走时的生物力学情况。与行走相比，太极拳可能在更安全的条件下对髋关节活动范围和神经肌肉系统协调性有更好的改善。它适用于髋骨关节炎患者和肌肉严重流失的老年人，还需要进一步的临床研究来证实。
