Working Principle Pelvic floor muscle trainer is a new technology for non-invasive in vitro stimulation of internal nerves. It uses time-varying magnetic fields to generate induced currents and high-frequency vibrations in tissues, which can penetrate clothing and reach the entire pelvic cavity. There is no need to undress/no probes/no disinfection. High-frequency pulses generate vibrations of different frequencies in the cushion through cables, and you can experience the vibration massage of the pelvic floor muscles by sitting. Sitting quietly for 30 minutes is equivalent to doing 10,000 Kegel exercises.
