Abstract— There is currently a strong need for new technical means for neuromotor rehabilitation in order to intensify treatment, to respond to the increase in the number of patients clogging up care services, to lower costs and, above all, to implement new rehabilitation approaches that are more effective and better scientifically based than the current therapies, which are largely based on empirical observations. This project aims to develop a new tool for neuromuscular reeducation. Its function is to improve the quality and the duration of muscular strengthening training sessions and training of motor function for patients suffering from muscle deconditioning. A "smart" electromyostimulator using, at the same time, techniques of electrostimulation (EMS) and analysis of electromyography (EMG) allows the control in real time electrical stimulation parameters considering the physiological fatigue of the stimulated muscle. This control, performed on stimulation parameters depending on electrical response of muscles (M wave), allows the muscle stimulation taking into account the muscular reaction to the electrical stimulation.
