Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals with self-reported endometriosis-associated pain that persists despite medical or surgical interventions.
✕Probably not a fit
Patients with contraindications to rTMS, such as those with metal implants or a history of seizures, will not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in reducing endometriosis-associated pain (EAP) in individuals who have not found relief from previous treatments. It employs a double-blind, randomized-controlled design with four groups receiving either real or sham rTMS for either 5 or 10 sessions. The study will assess pain outcomes and the potential benefits of different treatment durations. The protocol adheres to established reporting standards and focuses on patient-oriented research.
Why it matters
Potential benefit: If successful, this intervention could provide a new, effective treatment option for individuals suffering from chronic pain due to endometriosis.
How similar studies have gone: Previous feasibility trials have shown promising results for rTMS in reducing endometriosis-associated pain, indicating potential for success in this approach.
