Abstract: Objective To explore kinetic and motion characteristics of the upper extremity joints and establish a more systematic and comprehensive evaluation system of tuina. Methods Two groups of participants (n=10 in the expert group; n=10 in the student group) were recruited to record and analyze their rolling manipulation on 3 link joints (upper arm, forearm, hand) and 3 joints (shoulder joint, elbow joint, wrist joint). A multi-rigid-body sports biomechanical model was established by using motion capture system. Real-time data throughout the process was collected; Work-station software was used to analyze the data. Results The established multi-rigid-body sport biomechanical model of 3 link joints and 3 joints with definite marker point could be used to describe rolling motion characteristics. In the extension phase of rolling manipulation, elbow extension degree and forearm rotation angle was 38.304±1.776°and 58.706±1.675°in the expert group; 18.199±1.675°and 42.556±2.812°in the student group, respectively. The differences were both significantly different (P<0.05). The wrist flexion degree in the experts group was 79.516±1.654°, and 78.451±2.110° in the student group, which was not significantly different (P>0.05). Conclusion The established 3-link 3- joint multi-rigid-body sport biomechanical model of rolling manipulation can simulate the spatial motion relation of each joint in the study of tuina manipulation, clarify the movement displacement and determine the space angle, which is suitable for the study of tuina techniques.
