Title: Combined Sono-electro-magnetic Therapy for Treatment of Refractory Chronic Pelvic Pain Syndrome: A Prospective, Randomized, Double-blind, Placebo-controlled Trial
Brief Summary: Treatment of chronic pelvic pain syndrome (CPPS) is challenging for patients and physicians once conventional therapies fail.

We hypothesize that combined sono-electro-magnetic therapy can improve refractory CPPS in men. In addition, we postulate that combined sono-electro-magnetic therapy as well as placebo therapy has a significant effect on brain activity detectable by functional MRI.
