摘要
目的为研究脊柱推拿时所发出咔哒声响,提供一套可采集、定位和分析的检测仪器。方法在回顾咔哒声响测量技术现状的基础上,分析研究了实现声响测量的技术路线,设计了由时钟脉冲发生器、发送/接收接口、校准波发生器、复合传感器、计算机、测定分析软件以及输出部件等组成的声响测量系统。结果经初步试验,在40cm的距离上测到了关节发出的咔哒声响,说明技术上基本可行。结论本仪器可以作为脊柱推拿所致咔哒声响的采集、定位和分析系统使用。
Objective To design a set of equipment to collect, locate and analyze the cracking sounds during spinal manipula- tion. Methods On the basis of reviewing the current techniques for cracking sound measurement, we designed a cracking measurement system consisting of a pulse generator, transmission/reception interface, calibrating wave generator, compound sensors, computer, analytical software, and output components. Results Preliminary experiments demonstrated that the cracking sounds could be detected at a distance of 40 cm, suggesting that this system was technically feasible with some improvements to be made. Conclusion This device can be used for collecting, locating and analyzing the cracking sounds during spinal manipulation.
