A novel approach to surface electromyography: An exploratory study of electrode-pair selection based on signal characteristics

Abstract

A 3×4 electrode array was placed over each of seven muscles and surface electromyography (sEMG) data were collected during isometric contractions. For each array, nine bipolar electrode pairs were formed off-line and sEMG parameters were calculated and evaluated based on repeatability across trials and comparison to an anatomically placed electrode pair. The use of time-domain parameters for the selection of an electrode pair from within a grid-like array may improve upon existing electrode placement methodologies. © 2012 Kendell et al.; licensee BioMed Central Ltd.
