Treatment of vulvar vestibulitis syndrome with electromyographic biofeedback of pelvic floor musculature.

Thirty-three women diagnosed as suffering from vulvar vestibulitis syndrome, marked by a significant history of long-term moderate to severe chronic introital dyspareunia and tenderness of the vulvar vestibule, were selected for treatment. Patients were given a computerized electromyographic evaluation of the pelvic floor muscles and were then provided with portable electromyographic biofeedback instrumentation and instructions on the conduct of daily, at-home, biofeedback-assisted pelvic floor muscle rehabilitation exercises. They received intermittent evaluations of pelvic floor muscles to ensure compliance and monitor their progress and symptom changes. The results show that after an average of 16 weeks of practice, pelvic floor muscle contractions increased 95.4%, resting tension levels decreased 68%, and the instability of the muscle at rest decreased by 62%. Subjective reports of pain decreased an average of 83%. Twenty-eight patients had abstained from intercourse for an average of 13 months. Twenty-two of these 28 patients resumed intercourse by the end of the treatment period. Six month follow-up indicated maintenance of therapeutic benefits.
