Abstract: A perineometer for home or clinical use assesses the strength of pelvic floor muscles and provides audible and visual biofeedback signals as training aids during pelvic exercises. Impedance signals proportional to vaginal contraction pressure forces are developed by a transducer sleeve that is mounted on a vaginal probe. A battery-powered RF transmitter module contained within the probe transmits wireless impedance signals to a hand-held receiver equipped with an audio-visual display monitor. The probe reacts the pelvic contraction forces and thus provides a direct tactile feedback signal that is used in combination with audible and visual feedback signals for improving the endurance and strength of pelvic floor muscles.
