Pudendal Nerve Palsy • PNP is a severe pain on one side of the perineum, which is typically increased during sitting and reduced on a toilet seat. It is also associated with increased latency of the pudendal nerve following vaginal delivery.
Causes/Risk Factors • Hypertonic OI muscles (restricting space in Alcock's canal) • Compression of the deep dorsal vein of the clitoris • Vaginal delivery associated with a heavy fetus or a prolonged second stage of labor
Signs and Symptoms • Persistent and unwanted genital arousal • Pelvic engorgement • Pelvic and vulvar area heaviness and pressure after standing • Hypertonus pelvic floor musculature • Multiple trigger points • Urinary and/or anal incontinence • Pudendal latency
PT Implications and Treatments • STM • Persistent Genital Arousal Disorder PGAD • V-brace (designed to support the vulva in a manner similar to a male athletic belt) • Avoid prolonged standing • Perform daily pelvic floor exercise of 20-30 5 second contractions • Regular swimming - to improve LE circulation
