The quantitative and reproducible analysis of the standard body movement in Tai Chi Chuan (TCC) was performed in this study. We aimed to provide a reference of the upper extremities for standardizing TCC practice. Microsoft Kinect was used to record the motion during the practice of TCC. The preparation form and eight essential forms of TCC performed by an instructor and 101 practitioners were analyzed in this study. The instructor completed an entire TCC practice cycle and performed the cycle 12 times. An entire cycle of TCC was performed by practitioners and images were recorded for statistics analysis. The performance of the instructor showed high similarity (Pearson correlation coefficient () = 0.71 ~ 0.84) to the first practice cycle. Among the 9 forms, lay form had the highest similarity ( = 0.90) and push form had the lowest similarity ( = 0.52). For the practitioners, ward off form ( = 0.51) and roll back form ( = 0.45) had the highest similarity with moderate correlation. We used Microsoft Kinect to record the spatial coordinates of the upper extremity joints during the practice of TCC and the data to perform quantitative and qualitative analysis of the joint positions and elbow joint angle.
本研究旨在对太极拳（TCC）的标准身体动作进行定量且可重复的分析，为 TCC 的标准化实践提供上肢参考。本研究使用 Microsoft Kinect 记录 TCC 练习过程中的运动。分析了一名教练和 101 名练习者的准备姿势和八种基本姿势 TCC。教练完成了整个 TCC 练习周期，并进行了 12 次循环。练习者完成了整个 TCC 循环，并记录图像进行统计分析。教练的表现与第一练习周期高度相似（Pearson 相关系数 () = 0.71 至 0.84）。在 9 种姿势中，起势具有最高的相似度（ = 0.90），推势具有最低的相似度（ = 0.52）。对于练习者来说，搂膝拗步（ = 0.51）和云手（ = 0.45）与中度相关的相似度最高。我们使用 Microsoft Kinect 记录了 TCC 练习过程中上肢关节的空间坐标，并使用这些数据对关节位置和肘关节角度进行定量和定性分析。
