Embodiment

[0049] see Figure 3a and b, where, Figure 3a ROC curve analysis diagram based on RMS, IEMG time-domain eigenvalues, Figure 3b It is the ROC curve analysis diagram based on MPF ​​and MF time-domain eigenvalues. pass Figure 3a It can be seen from and b that the ROC curve is used to analyze the correct rate and error rate of the four eigenvalues ​​of RMS, IEMG, MPF, and MF to judge lumbar disc herniation. Among them, the ROC curve refers to the receiver operating characteristic curve (receiver operating characteristic curve), which is a comprehensive indicator reflecting the sensitivity and specificity of continuous variables, and uses the composition method to reveal the relationship between sensitivity and specificity. Set a number of different critical values ​​to calculate a series of sensitivity and specificity, and then draw a curve with the sensitivity as the vertical axis and (1-specificity) as the horizontal axis. The larger the area under the curve, the more accu...

Abstract

The invention provides a lumbar intervertebral disc protrusion determination method and system. The determination method includes: acquiring surface electromyogram signals of a waist and a back; performing filtering treatment on the acquired surface electromyogram signals; performing feature value extraction on the filtered surface electromyogram signals; and performing comprehensive analysis on a waist muscle and a back muscle according to the acquired feature values so as to determine lumbar intervertebral disc protrusion. The lumbar intervertebral disc protrusion determination method and system are simple and practical, can perform preliminary determination on a lumbar intervertebral disc without the complex principle and complex devices; and the determination method can achieve therapeutic effect evaluation and recovery evaluation on the lumbar intervertebral disc protrusion, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of electromyography signal processing, in particular to a method and system for judging lumbar disc herniation. Background technique [0002] In recent years, with the increasing social pressure and life pressure, the pace of human life and work has accelerated, and the incidence of lumbar disc herniation has shown an upward trend year by year. Lumbar disc herniation is more common in young people, and the course of the disease is relatively long, which has a great impact on the health and life of patients. Therefore, early diagnosis and symptomatic treatment are the hot spots of many medical workers. [0003] Lumbar disc herniation is relatively common clinically, and lumbar disc herniation can easily cause lumbosacral nerve root compression in patients. Clinically, the diagnosis of lumbar disc herniation is mainly based on the patient's clinical symptoms combined with imaging, which requires relatively h...
