Vaginal probe with double circuit (4 electrodes) for perineal re-education, ? through EMG biofeedback and electrostimulation. It is characterized by a double circuit, consisting of 4 electrodes arranged radially, designed to intercept the two branches (left and right) of the pubococcygeal muscle separately. It offers the advantage of being able to treat the two branches of the pubococcygeal muscle asymmetrically and independently but simultaneously with 2 electrostimulation channels or 2 EMG biofeedback channels (for muscle asymmetry results from episiotomy). The electrodes of the PERISPHERA®-H probe are perfectly suited to the vaginal cavity at rest which is characterized by an "H" profile. The two pairs of electrodes that intersect the left and right branches of the pubococcygeal muscle allow the separate recognition of the action potential (EMG) produced by each of the two branches in the contraction phase, which provides the rehabilitator with objective information on the state of the pelvic floor muscle. The PERISPHERA® perineal probes are made entirely of biocompatible plastic material, with gold plated metalized electrodes. The electrical connection with the stimulation or the EMG-biofeedback unit is obtained by two or four wires (about 20 cm in length) with a 2mm female banana ending. The probe can be used with any equipment supplying symmetric biphasic pulses, zero average value (galvanic-free). Each probe is supplied unsterilized in a single sealed bag, placed in individual box containing the package leaflet with instructions for use.
