Abstract

Information concerning the firing pattern is difficult to retrieve from the electromyographic (EMG) signal, because of superposition of information concerning the motor unit potential morphology. Muscular sound can provide a useful tool for a better insight into the firing mechanisms because it reflects only the mechanical aspects of neuromusclar activation. This study verifies the existence of correlated frequency components in the power spectrum of the two signals, in the physiological ranges which characterize the selected contraction levels.
