Evaluation of the Efficacy and Tolerability of a Transcutaneous Electrical Nerve Stimulation (TENS) Device for the Management of Endometriosis-associated Pain

NA · Monath Electronic · NCT07393295

This study tests whether two types of TENS (conventional and microstimulation) can reduce chronic pelvic pain in adults with endometriosis or adenomyosis who are on stable hormone therapy.

What this trial studies

ELECTRE is a single-center, randomized, prospective, longitudinal, controlled, two-arm, single-blind trial with a 4-week run-in period followed by a 4-week randomized treatment phase and a 4-week extension in which all participants receive active TENS. Participants are randomized 1:1 to conventional TENS or microstimulation TENS and are asked to limit other pain medications to specified options. Eligible participants are adult women with imaging or histology-confirmed endometriosis or adenomyosis, chronic pelvic pain for more than six months, and stable hormone treatment. The trial measures tolerability and pain outcomes to compare the two TENS approaches.

Who should consider this trial

Good fit: Adult women (≥18 years) with imaging- or histology-confirmed endometriosis or adenomyosis, chronic pelvic pain >6 months, on continuous stable hormone therapy with no planned changes, able to limit other analgesics, and with internet access are ideal candidates.

Not a fit: People who are pregnant, breastfeeding, menopausal, experiencing an acute worsening of disease, not on stable hormone therapy, or who require stronger pain medications are unlikely to be eligible or benefit.

Why it matters

Potential benefit: If successful, this could provide a non-drug, self-administered option to lessen chronic pelvic pain for people with endometriosis or adenomyosis.

How similar studies have performed: Several small studies and reports have suggested TENS can help pelvic pain related to endometriosis, but prior evidence is limited and mixed in quality.
