A human body balance signals measuring system and the method of analysis thereof that has a measuring device, a filter amplifier, an A/D convertor (analog to digital convertor), a signal receiving module, and a data analyze module. The measuring device is linked with the filter amplifier. The filter amplifier can detect and collect the voltage signals caused by pressure change and then filter and amplify the signals. The signals are send to the A/D convertor to convert the analog circuit signals into digital signals for the receiving module to use these voltage change values for human body center of gravity offset evaluation to obtain the COP (center of pressure) offset and COP offset velocity. The data analyze module uses the measured body center of gravity offset for MSE (multiscale entropy) to quantitative the dynamic of human body center of gravity and verify the accuracy of this measuring system. |
