Electrode Placement in Surface Electromyography (sEMG) ”Minimal Crosstalk Area“ (MCA)

Abstract

This paper is an introduction to a workshop on electrodes location and specific exercises. Selectivity of EMG electrodes depends on their interspacing, their conductive area and axis direction with respect to the direction of the underlying muscular fibres. Minimal cross talk area (MCA) helps to limit or avoid crosstalk from neighbouring muscles. We present examples of MCA and typical sEMG patterns during specific exercises.
