Abstract: An electrical neuromuscular stimulation comprising at least one stimulation unit, which is portable and autonomous, controlled by a detachable and interchangeable information medium, previously programmed as a function of the treatment for each respective patient, equipped at its output with at least one pair of electrodes designed to be applied to the part of the patient's body to be treated and to transmit trains of electrical stimulation impulses intended to cause contractions and muscular exercise or training, said stimulation unit comprising an electronic circuitry (hardware) of the amorphous type, under the supervision of a control software with interactive parameters and linked by coupling and interaction functions, with said software being memorized on the detachable information medium, with it being possible for the value of each parameter to evolve progressively throughout the program between previously programmed reference values, and any parameter being able to control another parameter.
