The new vaginal-probe "Periform" was contrived for an pleasant and effective application of muscle-stimulation-devices. The probe can be used with or without pelvis-bottom-contraction-indicator. Together with the pelvis-bottom-contraction-indicator, the probe can be used also without EMG bio-feedback or electro-stimulation-device. The probe enabled an extraordinarily instructive control of a correctly enforced pelvis-bottom-contraction.
