A method and device for training pelvic floor muscles in order to treat or prevent
urinary or fecal incontinence. The device comprises a probe having a pressure sensor
and a vibrator, and a microprocessor connected with the sensor and the vibrator.
Initially, the probe is inserted into a person's vagina or rectum and the highest
force that can be applied by the person contracting the pelvic muscles is ascertained
and registered. The contraction of the pelvic floor muscles is repeated at intervals,
and the force applied by pelvic floor muscles at each contraction is ascertained
and compared with the registered highest value. The vibrator is activated at each
contraction of the floor muscles only if the force has a predetermined relationship
to the registered value, and only for a predetermined period as long as the predetermined
relationship is maintained.
