AIM: Demonstration of analgesic effects of electromagnetic field treatment in cases of chronic refractory pelvic pain. STUDY DESIGN: Prospective non-controlled trial, 64 women complaining about pelvic pain of at least 6 months duration, resistant to standard therapies, submitted to electromagnetic field applications on both iliac regions by Thelf Systems apparatus by two applications daily lasting 2 hours each for 20-40 days. Control visit after 3 months. RESULTS: Complete subsidence of pain in 39 cases (61%), in 15 patients (23%) relief during treatment, then mild endopelvic tension after a 3-month control; in 10 cases (16%) symptoms reduced only during application hours, unchanged at follow-up. Outcome of treatment appears to be independent of pre-existent psychosocial variables. CONCLUSION: Magnetic therapy shows a real analgesic effect on pelvic pain, and seems to contribute to resolution of complex interactions between somatic nociceptive stimuli and psychosocial implications affecting pain perception in these patients
