Emg interference pattern
WebAs contraction increases, the number of muscle action potentials increases, forming an interference pattern. Denervated muscle fibers are recognized by increased activity with needle insertion and abnormal spontaneous activity (fibrillations and fasciculations); fewer motor units are recruited during contraction, producing a reduced ...

WebJan 1, 1984 · Abstract. A method is described for the automatic analysis of EMG interference patterns obtained at optional non-controlled force levels. It is a modification of Willison's method of measuring ... WebThe complexity of the EMG interference pattern varies with contraction effort, from a few motor units to a “full” pattern. The fullness of the pattern is usually visually estimated, but can be quantitated. As the pattern increases, more motor units are added, resulting in higher amplitude and more complex signals.
