一指禅推法技术要领的运动学分析

目的：测试一指禅推法的运动过程,量化分析一指禅推法＂沉肩＂、＂垂肘＂、＂悬腕＂的技术要领。方法：纳入具有不同推拿技术水平的测试者,分为专家组、熟练组和初学组,在测试者手背上选取8个标记点,用Motion三维运动解析系统分析运动数据。结果：三组测试者＂沉肩＂的运动学数据变异系数差异不明显（P=0.825）,肩关节稳定状态时上臂与躯干的夹角稳定在60°～70°范围内;专家组和初学组测试者＂垂肘＂的运动学数据有显著性差异（P=0.026）;三组测试者的屈腕角度数值差异不显著（P〉0.05）,基本维持在50°～60°。结论：手法运动学数据变异系数可客观评价一指禅推法＂沉肩＂要求;＂垂肘＂要求肘关节标记点低于腕关节标记点3～4 cm;＂悬腕＂时腕关节应该自然屈曲呈50°～60°角。

Kinematic Analysis on Technical Actions of Pushing Manipulation with Thumb

Objective： To test the operation process of pushing manipulation with thumb in order to analyze quantitatively the technology essentials of ＂Chenjian,Chuizhou and Xuanwan＂.Methods：A total of 15 subjects with 3 different Tuina technique level were included and divided into expert group,skilled group and novice group,and the 3D motion analysis system was used to collect kinematic data from 8 body markers.Results： There was no significant difference among three groups in the coefficient variation of ＂Chenjian＂ kinematic data（P=0.825）,and the angle between trunk and arm was about 60~70°.There was an obvious difference between expert group and novice group in ＂Chuizhou＂ kinematic data（P=0.026）.The flexion angle of wrist in three groups was around 50~60°,and there was no significant difference among three groups（P0.05）.Conclusion： The coefficient variation of manipulation kinematic data can be considered as an evaluation standard of ＂Chenjian＂.According to the technical requirement of ＂Chuizhou＂,the marker of humeroradial joint is 3~4 cm below the marker of processus styloideus radii.The flexion angle of wrist should maintain about 50~60° when the motion of ＂Xuanwan＂ is operated.
