Electrical stimulation, Biofeedback (EMG), Evoked (EMG-triggered) stimulation

The therapeutic unit evoStim® E is an electromedical equipment for perineal re-education by electrostimulation and EMG biofeedback. It allows passive perineal treatments (with 1 electrostimulation channel), active perineal recovery (with 1 biofeedback channel) and perineal muscular re- learning (by EMG-triggered electrostimulation).

It is intended for both professional use and personal use by the patient.

Biofeedback is of EMG type, and can be applied either on perineal muscles (with vaginal / anal probe) or on external muscles (with transcutaneous self-adhering electrodes). Since the acquired EMG signal is in the order of a few μV, EMG biofeedback also requires the use of a transcutaneous reference electrode, essential for the suppression of electrical interference.

Visual feedback on the display consists in switching-on a number of concentric circles proportional to the pressure exerted on the balloon of the probe by perineal muscles, during a voluntary contraction. With the range self- calibration, administering biofeedback programs is quite easy with the evoStim® E unit.
