Description

technical field [0001] The invention relates to a diagnosis and treatment system based on surface electromyography, which belongs to the fields of sports science, rehabilitation medicine and biomedical engineering. Background technique [0002] Surface Electromyogram (sEMG) is a one-dimensional voltage time-series signal obtained by guiding, amplifying, displaying and recording bioelectrical changes when the neuromuscular system performs voluntary and involuntary activities, and its amplitude is 0-5000μV, frequency 30-500Hz. There are different degrees of correlation between the surface electromyographic signal and the activity state and functional state of the muscle. It has been widely used in sports science, such as the rationality analysis of sports technology, fatigue judgment, non-injury prediction of anaerobic valve and muscle fiber Types, etc.; clinical medicine, such as neuromuscular assessment, biofeedback therapy, rehabilitation therapy, etc. have important value...

AI Technical Summary

Problems solved by technology

[0004] Chinese patent CN201958882U discloses a monitoring device for skin surface electromyography, which uses dual-electrode detection, and the notch level uses a double-T active network, which overcomes the low input impedance, large information loss and power frequency of the commercially available German skin surface sensor. The problem of weak interference ability

[0007] From the above analysis, it can be seen that some existing EMG devices have fewer electrode channels, so the evaluation of the overall condition of the patient often requires repeated placement of electrodes and repeated detection, which is time-consuming and labor-intensive.

In addition, more importantly, most of the equipment has a single function, and can only complete the function of EMG collection and evaluation or electrical stimulation therapy alone. It is effectively combined with treatment and guides the setting of electrical stimulation parameters, which has caused certain difficulties for the formulation of a better rehabilitation training program for patients
