中文摘要：

目的通过对提插和捻转两种针灸手法手部相关关节运动角度的精确测定,为针灸手法提供量化依据。方法招募6名有3年以上针灸经验的针灸师志愿者和1名受试者参与实验。运用NDI视频动作捕捉系统,测定提插和捻转两种针灸手法时前臂、腕关节、拇指和食指掌指关节、拇指和食指指间关节的角度,并比较6名针灸师在人体大腿上操作10次提插、捻转手法时前述关节角度变化幅度的差异。结果针灸师手部主要关节角度的变化幅度无显著差异（P〉0.05）。提插手法主要由腕关节的背屈运动完成,幅度为7.23°±1.87°;捻转手法主要由食指指间关节屈曲完成,其中食指第1、2指间关节运动幅度分别为28.33°±2.18°、10.43°±1.69°。结论视频动作捕捉可以作为量化针灸手法参数的方法;不同的针灸操作手法表现出特异性的关节角度变化,特异性的关节角度变化可以作为量化针灸操作手法的依据。

英文摘要：

Objective To accurately measure the motion angels of hand-related joints when manipulating acupuncture needle for thrusting-pulling and twirling,so as to provide quantitative references for acupuncture manipulation. Methods Six acupuncturists with over 3-year acupuncture experience and one volunteer were enrolled in this study. The angles of the forearm,wrist,metacarpophalangeal interphalangeal joints of the thumb and index finger for each acupuncturist when performing thrusting-pulling and twirling manipulation were measured by the video motion capture（ VMC） system,and the different ranges of above-mentioned angles among the 6 acupuncturists when performing 10 trails of thrusting-pulling and twirling manipulations on the volunteer＇s thigh were compared. Results There was no significant difference in the ranges of relevant hand-related angles among the acupuncturists（ P〉 0. 05）. The manipulation of thrusting-pulling was mainly managed by the wrist joint,with the range of 7. 23° ± 1. 87°,while the manipulation of twirling was mainly managed by the interphalangeal joints of the index finger,and the range of the first and second interphalangeal joints of the index finger was 28. 33° ± 2. 18°and 10. 43° ± 1. 69°,respectively. Conclusions The VMC can be a reliable method to quantify the parameters of acupuncture manipulation. Different acupuncture manipulation shows particular variation of the joint angles,which can be used as a reference to quantify acupuncture manipulation.
