Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 20–25 with physician-diagnosed primary dysmenorrhea, regular menstrual cycles, BMI ≤30 kg/m2, not using hormonal contraception or an intrauterine device, and without pelvic pathology or lower‑limb neuropathies.

Probably not a fit

Patients with secondary dysmenorrhea due to gynecologic disease, those using hormonal contraceptives or an IUD, smokers, people with severe comorbidities or lower‑limb neuropathies, or those outside the age/BMI limits are unlikely to benefit from this protocol.

What this trial studies

This interventional trial enrolls women aged 20–25 with primary dysmenorrhea and BMI ≤30 who have regular menstrual cycles. Participants receive transcutaneous tibial nerve stimulation (TTNS) applied at the superomedial ankle region, with outcomes compared to traditional NSAID treatment. The approach is based on shared spinal segments between the posterior tibial nerve and pelvic autonomic nerves, which may rebalance spinal impulses that influence uterine pain. Main outcomes will focus on menstrual pain intensity and related functional measures across menstrual cycles.

Why it matters

Potential benefit: If successful, TTNS could offer a non-drug, low‑risk option to reduce menstrual cramp pain for women with primary dysmenorrhea.

How similar studies have gone: Tibial nerve stimulation has shown benefit in other pelvic conditions such as overactive bladder and some pelvic pain reports, but its use specifically for primary dysmenorrhea is limited and relatively novel.
