To design a set of equipment to collect, locate and analyze the cracking sounds during spinal manipulation.
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.
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.
This device can be used for collecting, locating and analyzing the cracking sounds during spinal manipulation.
