The effect of electrode dislocation on lower back surface electromyography amplitude

Abstract

Surface Electromyography (SEMG) plays an important role in the understanding of trunk muscle activity during various postures and movements. The Root Mean Square (RMS) is used to quantify the muscle activation amplitude and was shown to be a valuable parameter in research focusing on the etiology and maintenance of chronic lower back pain.\ud The aim of the current study was to determine the effect of electrode dislocation on the RMS of the low back muscles
