Electrostimulation & pressure Biofeedback

The therapeutic unit evoStim® P is an electromedical equipment for perineal re-education by intra-vaginal electrostimulation and pressure biofeedback. It allows passive perineal treatments (with 1 electrostimulation channel), active perineal recovery (with 1 biofeedback channel) and perineal muscular re-learning (by pressure- triggered electrostimulation).
It is intended for both professional use and personal use by the patient.


  • Large LCD with touch-screen
  • Six quick selection touch-buttons
  • Pre-set & editable programs
  • Circular visual feedback
  • Bar-graph visual feedback
  • Multi-color back-light
  • One channel stimulation
  • One channel biofeedback
  • Triggered stimulation

The perineal biofeedback is of manometric type, it can be carried out with the special balloon probe supplied in the package or with any type of probe equipped with Luer-lock female pneumatic link.

Visual feedback on the display is obtained by switching-on a number of concentric circles proportional to the pressure exerted on the probe balloon by perineal muscles during a voluntary contraction.
