About

This study assesses whether the addition of chemodenervation to an established regimen of pelvic floor physical therapy for painful high tone pelvic floor dysfunction improves patients' objective and subjective outcomes. Study subjects will select one of three treatment approaches: injection of 50 units Botulinum toxin A with local sedation as an office procedure, injection of 100u BoNTA-cosmetic in either the office or while anesthetized, or injection of 150 units Botulinum toxin A while anesthetized.

Full description

High-tone pelvic floor dysfunction is often a painful condition that can be associated with a number of female pelvic syndromes including childhood elimination disorders, idiopathic urinary retention, vaginismus, dyspareunia, pelvic pain, constipation, sport injuries, postoperative and bladder pain syndrome/interstitial cystitis. Following appropriate patient education about pelvic floor function, mainstays of therapy for high-tone pelvic floor dysfunction pelvic pain include pharmacotherapeutic agents and pelvic floor physical therapy. The investigators hypothesize that chemodenervation with Botulinum toxin A will offer a safe, efficacious intervention for women with high tone pelvic floor dysfunction that cannot be adequately treated with pelvic floor physical therapy alone.
