胸椎掌按法所致“咔哒”声响与最大按压力的量效关系

A study on dose-effect relationship of the cracking sounds and the biggest pressure by the manipulation of palm-pressing on thoracic vertebrae

目的:研究胸椎掌按法作用时"咔哒"声响与最大按压力的量效关系,为推拿手法的量化提供定量化依据。方法:利用压力检测系统,检测并记录胸椎掌按法操作时出现"咔哒"声响时术者手掌按压患者胸椎棘突的最大按压力。结果:以"咔哒"声响作为胸椎掌按压法成功的标志,通过出现声响的最大按压力(247.21±8.02 mmHg)和没有出现"咔哒"声响的最大按压力(251.15±2.87mmHg)的比较,两者之间没有显著差异(P>0.05)。结论:胸椎掌按时按压力大小和"咔哒"声响的发生没有直接关系。

Objective： To study dose-effect relationship between the cracking sounds and the biggest pressure by the manipulation of palm-pressing on thoracic vertebrae,to provide a basis for quantitative analysis of manipulation strength . Method： The maximum stress of the palm-pressing against the patients, thoracic vertebrae was tested and recorded with a pressure sensor testing system. Result： The cracking sounds was a sign of successful manipulation of palm-pressing on thoracic vertebrae. There was no significant difference between the maximum stress （247.21±8.02 mmHg） of palm-pressing with cracking sounds and the maximum stress （251.15±2.87 mmHg） without sounds （P〉0.05）. Conclusion： There was no direct relationship between manipulative strength and cracking sounds during palm-pressing on thoracic vertebra.
