An Investigation of HDEMG Spatial Parameters in Individuals with Transtibial Amputation

Abstract

Surface electromyography (EMG) can provide insight regarding muscle activity and is a useful method to better understand neuromuscular function. Recently multichannel electrode grids or high density EMG has been used to provide spatial muscle information. This tool can be particularly valuable to study residual muscle activity after amputation. The purpose of this study was to use high density EMG to examine spatial muscle parameters in those with transtibial amputation and compare with able-bodied control participants. A comparison of these parameters is presented. This study also showed that HDEMG can be successfully used with those with lower limb amputation.
