The Electromyogram and Mechanomyogram in Monitoring Neuromuscular Fatigue: Techniques, Results, Potential Use within the Dynamic Effort

The paper provides a functional, practically oriented overview of the concept and technical possibilities of monitoring the neuromuscular fatigue via the electromyographic and the mechanomyographic signals, as essentially related to the muscle contraction and intimately mirroring muscle activation and contraction mechanisms. The Fast Fourier Transform-based and Wavelet Transform-based techniques are critically analysed, illustrated and discussed, on the international arena and through original work. An original technique the Area/Amplitude Ratio (Raa) is also comparatively discussed, as a practical alternative instrument in monitoring the neuromuscular fatigue in a dynamic contraction important issue in real life activity , e.g. work in difficult environments, pilots in mission, difficult work in normal environments.
