Study Details
Study Description
Brief 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.

Detailed Description
Pulse diagnosis is an important method to judge the status of patients in the process of diagnosis and treatment of traditional Chinese medicine. At present, the commonly used site of pulse diagnosis is the radial artery, which is divided into "cun", "guan" and "chi". Whether the diagnosis of lumbar disc herniation can be realized through pulse diagnosis has not been solved. Herniation of the lumbar intervertebral disc is a syndrome caused by degeneration of intervertebral disc, partial or complete rupture of the annulus fibrosus, protrusion of nucleus pulposus, or compression of nerve roots and cauda equina. In the area of compression, the blood supply is also limited to a certain extent, and the blood that should be in the normal laminar flow state gradually turns into a turbulent state, causing abnormal vibration, which is fused with a larger cluster of sound waves transmitted by the heart and then transmitted throughout the body. In this situation, the investigators can feel the combination of abnormal vibration waves by touching the pulse at different levels of the arteries near the surface of the body, including the radial artery. In long-term clinical practice, the investigators have found that the ulnar radial pulse of patients with lumbar disc herniation, i.e. the fifth layer of the ulnar radial pulse, often presents an unsmooth pulse. Therefore, the investigators believe that patients with lumbar disc herniation may have abnormal sound waves in the radial artery.
The investigators have found that there are low-frequency sound waves in the radial artery, which carry the physiological and pathological information of the organs in the body, and developed the "Pulse Detection System of Sound Waves". Previous projects have achieved certain results after exploring the abnormal sound waves of the radial artery in patients with sequelae of cerebral infarction, stable coronary heart disease, chronic gastritis and other diseases.
Therefore, this study will use the "Pulse Detection System of Sound Waves" to collect the sound waves in the radial artery of both hands from 45 patients with lumbar disc herniation and 45 relatively healthy people and carry out spectrum analysis and wavelet analysis to extract the pulse characteristics. The sensitivity and specificity of "Pulse Detection System of Sound Waves" in the diagnosis of lumbar disc herniation will be calculated. Supposed there are characteristic sound waves in the radial artery of patients with lumbar disc herniation, and these characteristic sound waves have some specific distributions, planes, and points that are different from the sound waves of relatively healthy persons. Then this study will explore and gradually confirm such characteristics and differences. It is expected to contribute to the pulse diagnosis of lumbar disc herniation.
