In this article we present a mathematical model of the bipedal gait as well as the respective simulation of the joint movement that makes it possible. The data acquisition was carried out with the Tracker® software, and the dynamic simulation is presented in MATLAB® based on the obtained data. From this procedure, a perspective of the displacement generated by the lower train of the digitized human body is generated, which allows a study of the most concrete and successful movement for medical studies, since it allows the implementation of
