Summary

The purpose of this study is to use the " Pulse Detection System of Sound Waves " to collect the pulse information of recruited subjects, and to extract characteristic pulse information by multi-scale entropy, Fourier transform, Hilbert yellow transform, spectrum analysis, wavelet analysis and other methods. Evaluate the specificity, sensitivity, positive likelihood ratio and negative likelihood ratio of the "Pulse Detection System of Sound Waves" in the diagnosis of lumbar disc herniation.
