Simulation analysis of interference EMG during fatiguing voluntary contractions. Part II – Changes in amplitude and spectral characteristics

Abstract Capabilities of amplitude and spectral methods for information extraction from interference EMG signals were assessed through simulation and preliminary experiment. Muscle was composed of 4 types of motor units (MUs). Different hypotheses on changes in firing frequency of individual MUs, in...
