Web1 sep. 1988 · The underlying principle of this technique is that some motor units are not recruited during an isometric maximal voluntary contraction (MVC) and applying a supramaximal electrical stimulation to the muscle or peripheral nerve during MVC should activate those motor units (Hales and Gandevia, 1988). WebMaximal voluntary isometric contraction, a method quantitatively assessing muscle …
WebThe results showed an EMG coefficient of variability of 21.61%, indicating that this variability must be considered in experiments with an inappropriate condition for normalization procedures, such as EMG biofeedback in rehabilitation sessions, or normalization procedures by the maximal isometric voluntary contraction.
