颈椎微调手法的力学特性分析

Mechanical properties of cervical spine manipulation with fine adjustment

目的对脊柱微调手法的颈部操作进行力学特性分析,为该推拿手法的临床推广提供可参考的力学数据。方法微调手法创始人、手法熟练者和手法初学者3位测试者用微调手法在健康人体颈椎两个节段上操作,采用FingerTPS Wireless System采集拇指力量大小的数据,分析在右手拇指力量最大时双手拇指力量大小的差异,以及拇指力量大小随时间变化的规律。结果各测试者双手拇指力量最大值之间存在明显差异(P<0.001);不同的手法测试者在应用脊柱微调手法时,都存在作用力的加力过程(波谷至波峰的时间T1)比减力过程(由波峰至波谷的时间T2)略长,经统计学分析有明显差异(P<0.001)。结论微调手法操作上存在主力手和辅助手,微调手法操作是慢速加力和快速减力的过程。

Objective To analyze mechanical properties of cervical spine manipulation with fine adjustment, so as to provide mechanical data for popularization of such manipulation in clinic. Methods The founder, a skilled practitioner and a beginner of fine-adjusting manipulation operated the spinal fine-adjusting manipulation on two cervical vertebral segments of healthy subjects, respectively. The force data of thumbs were collected by Fin- gerTPS Wireless System to analyze force differences between two thumbs while the force of right thumb was in its peak value, as well as regular pattern of the thumb force in relation with time. Results Significant differences were found between the maximum force of two thumbs in each subject （ P 〈 0.001 ）. The process of force appli- cation （from trough to peak, /3 ） was longer than that of force reduction （from peak to trough, T2） when all the subjects operated spinal fine-adjusting manipulation, showing significant differences （P 〈 0.00l ）. Conclusions There exists the main and auxiliary hand during cervical spine manipulation with fine adjustment, which is actually a process of slow force application and rapid force reduction.
