DEVICE FOR FUNCTIONAL ELECTRICAL STIMULATION AND MEASUREMENT OF ELECTROMYOGRAM, COMPRISING MEANS FOR SHORT-CIRCUITING AND EARTHING A PAIR OF ELECTRODES, AND ASSOCIATED TRANSCUTANEOUS ELECTRODE
The present invention relates to a device for functional electrical stimulation and for measurement of electromyogram. The device includes at least one pair of active electrodes intended to be placed on the skin of a user, at least one stimulation module able to generate electric pulses, at least one measurement module able to receive electric pulses, a monitoring and processing unit linked electrically to the stimulation and measurement modules, with the monitoring and processing unit being able to monitor the electric pulses generated by the stimulation module and to process the electric pulses received by the measurement module, and a switching station linked electrically to the stimulation and measurement modules, to the monitoring and processing module, and to the pair of active electrodes. The switching station is able to electrically connect the pair of active electrodes with either the stimulation module, in the case where the pair of active electrodes has to be used to stimulate a muscle of the user, or the measurement module, in the case where the pair of active electrodes has to be used to measure the reaction of the muscle. The switching station is able to momentarily short-circuit and earth ground the pair of active electrodes so as to eliminate any residual voltage at the level of the active electrodes.
