Abstract

A perineometer exercise probe for home or clinical use assesses the strength of pelvic floor muscles and provides audible, visual and tactile biofeedback signals as training aids during pelvic exercises. The exercise probe is selectively operable in a passive reaction mode, in which audible, visual and tactile biofeedback signals proportional to pelvic muscle contractions are generated, and in an active vibrating mode in which therapeutic vibrations are applied directly to internal pelvic musculature with or without co-generation of biofeedback signals proportional to the strength of pelvic muscle contractions; and in a combination of both modes simultaneously. The probe reacts the pelvic contraction forces and thus provides passive tactile feedback signals that are experienced simultaneously with audible, visual and vibration-induced tactile biofeedback signals for improving the endurance and strength of pelvic floor muscles. Biofeedback signaling is facilitated by wireless two-way communication between the probe and a portable monitor.

Claims
