Abstract

Introduction: SURFACE ELECTROMYOGRAM DECOMPOSITION can be useful for the diagnosis of neuromuscular disease. Due to the surface detection problems and motor unit action potential (MUAP) overlaps, which increase with the muscle voluntary contraction (MVC), finding a solution to the DECOMPOSITION problem is a very important key. The number and the position of detection electrodes affect the DECOMPOSITION results. Therefore, a suitable solution will be the utilization of signal modeling and finding the best array of detection electrodes for DECOMPOSITION purposes. In this paper, the latest sEMG BICEPS modeling has been used to determine the best array of detection electrodes.Material & Methods: Latest BICEPS sEMG signal modeling was used in the following experiments for reaching the best array of detection electrodes.1- X-axis electrode displacement effect analysis for one motor unit.2- X-axis electrode displacement effect analysis for motor units with different size and depth.3- Z-axis electrode displacement effect analysis for motor units with same size and different position.4- Different coordination electrodes affect analysis for motor units with the same or different center.Results & Discussion: The results of this work can be used to find the best array and give some ideas for optimizing the DECOMPOSITION algorithms. The best position of motor unit signal detection is the above of motor unit and same direction with it. This position must be between innervations zone and tendon. Differential detection is preferred. For increasing DECOMPOSITION ability, X-axis electrode distribution must be the same as X-axis motor unit distribution.Because of uniform X-axis motor unit distribution in BICEPS, differential detection electrode with uniform X-axis distribution can be used. So, at minimum, three differential electrodes (six electrodes) must be used in the beginning, middle and the end of muscle width.
