Overview

The characteristics of matrix electromyography: Traditional electromyography is usually a study of the electrophysiological activity characteristics of the entire muscle, making it difficult to observe changes in the activity of local muscle fibers; However, due to its invasive nature and other reasons, needle electromyography cannot perform muscle fiber electrophysiological changes during exercise.

Matrix electromyographyCharacteristics:

Traditional electromyography (EMG) typically focuses on studying the electrophysiological activity characteristics of the entire muscle, making it difficult to observe changes in the activity of local muscle fibers; However, due to its invasive nature and other reasons, needle electromyography cannot perform muscle fiber electrophysiological changes during exercise. Matrix surface electromyography electrodes are used to analyze subtle changes in muscle electrophysiological activity in both temporal and spatial dimensions through matrix surface electromyography electrodes with extremely small spacing (1-8mm). This allows for in-depth exploration of muscle electrophysiological activity characteristics such as nerve innervation areas, nerve muscle fiber conduction velocity, motor unit analysis, encoding of muscle contraction characteristics, distribution of muscle fiber types, and muscle fatigue. It has a wide range of applications in research and application fields such as sports training, sports selection, homework evaluation, bionic prosthetic design, and intelligent robots.
