SEMG based model to simulate action potential of a single muscle fiber

Abstract

This work aims to describe a model which is able to simulate the action potential (AP) of a single muscle fiber. The model assumes muscle fibers have a cylindrical structure and are uniformly parallel distributed in an isotropic media. This model is based on a mathematical formulation of the relationship between the observation electrode and the extracellular longitudinal currents produced by the fiber muscle. The AP of a single muscle fiber is estimated by including parameters values related to the AP such as the dipoles length, radial and longitudinal conductivity in the presented model. The parameters related to the position of electrode, the inter-electrode distance and the electrode sizes are investigated on the presented simulation model.
