Inverse Problem in the Surface EMG: A Feasibility Study

Abstract

The aim of this work is the development of a localisation algorithm of the bioelectric sources using surface electromyographic (SEMG). in this paper, a feasibility study is presented : we simulate the resolution of the SEMG inverse problem. First, we developed a program modeling the SEMG signal of the biceps brachii. To resolve the inverse problem, the localisation algorithm uses an estimation procedure. We minimize the difference between calculated potential and observed potential by successive iterations. The procedure is applied successively to the defined zones of the geometrical arm cross-section. The program locates accurately an active motor unit in a given zone, regardless of time and distance.
