NCT ID NCT07317037
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a portable device called ActiTENS mini that uses mild electrical pulses to relieve chronic pelvic pain in women with endometriosis. About 208 women will try different stimulation strengths over 9 months to see if it reduces pain and improves quality of life. If it works, doctors may prescribe it as a drug-free option.
