## 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.

## Claims

### Claim 1

Apparatus for treating a muscle in the pelvic region comprising:
a probe of a width on the order of an inch to permit insertion into the adult human vagina, said probe having spaced electrode means thereon for applying currents to the body and strain gauge means for sensing the intensity of muscle contractions that tend to compress the electrodes;
a generator coupled to said electrode means, said generator constructed to generate trains of pulses at a repetition rate within the range of 100 per second to 400 per second; and
meter means coupled to said strain gauge means for providing an indication of the level of intensity of muscle contractions.
