What this trial studies

This open-label, single-arm clinical study investigates the effects of transcutaneous auricular neurostimulation (tAN) on women experiencing idiopathic heavy menstrual bleeding. Participants will undergo three menstrual cycles, with the first serving as a baseline without treatment, followed by two cycles where they will self-administer tAN sessions. Blood loss will be measured using the Pictorial Bleeding Assessment Chart (PBAC), and menstrual symptoms and quality of life will be assessed using standardized scales. The goal is to determine the efficacy of tAN in reducing menstrual bleeding and improving overall well-being.

Who should consider this trial

Good fit: Ideal candidates are regularly menstruating women aged 18-45 with a history of menorrhagia.

Not a fit: Patients who are pregnant, lactating, or have a known bleeding disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a non-invasive option for women suffering from heavy menstrual bleeding, potentially improving their quality of life.

How similar studies have performed: While the approach of using neurostimulation for menstrual issues is relatively novel, similar studies in other areas of pain management have shown promising results.
