Muscle disease monitoring method based on sEMG

Abstract

The invention aims at providing a muscle disease monitoring method based on multi-channel surface electromyography (sEMG). The method comprises the steps that preprocessing is conducted on multi-channel sEMG signals firstly, a first channel is selected as a reference, and differencing is conducted on the signals of other channels and the signal of the first channel; then distribution moments are extracted through a K-means clustering convolution kernel compensation (KMCKC) method, and a single waveform is extracted; finally, multiple features of the waveform are fused, and the muscle state is evaluated. Due to the fact that external interference has influence on all electrodes, by meas of differencing between the signal of the first channel and the sEMG signals of original multiple channels, the external interference is effectively reduced, subsequent detection results cannot be affected, and the accuracy of muscle detection is improved. By means of application of the multi-feature parameters, the instability of single-parameter monitoring is effectively avoided, and the monitoring robustness is promoted. By means of the muscle disease monitoring method based on the multi-channel surface electromyography (sEMG), the defects in the prior art are effectively overcome, and important application value is achieved.

Description

technical field

[0001] The invention relates to a method for monitoring muscle diseases based on multi-channel sEMG. Background technique

[0002] With the development of our society, people pay more and more attention to health, and the diagnosis or monitoring of muscle diseases has become the research focus in recent years. Common neurodegenerative muscle diseases include Alzheimer's, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. Taking amyotrophic lateral sclerosis (ALS) as an example, ALS is a neurodegenerative disease characterized by progressive destruction of motor neurons in the motor cortex, brainstem and spinal cord, leading to muscle atrophy, paralysis and death in patients. The annual incidence rate of the general population is about (2-3) / 100000, and the prevalence area is about (4-6) / 100000. In the United States and the United Kingdom, ALS accounts for 1 / 500-1 / 1000 adult deaths [3], which also means that in the United States al...
