Abstract: An electrical applicator for applying currents that cause repeated involuntary contractions of the pubococcygeous muscle. The repeated current applications are used to treat muscle structures that have been damaged during childbirth and/or weakened from disuse, and which have contributed to the pathological formation of cyctocoel, rectocoel, uterine prolapse, and bladder malfunctions. A probe is provided which is connected to a pulse generator that applies trains of pulses at intervals such as every two seconds, every train lasting for about one second and containing pulses of a repetition rate such as 200 pulses per second. The apparatus further includes means for sensing the intensity of muscle contractions.
