Is this trial a fit for you?

Likely a good fit

Ideal candidates are multiparous women (2 or more prior births) who delivered vaginally at term and intend to breastfeed within 48 hours of birth.

Probably not a fit

Patients unlikely to benefit include those with contraindications to TENS or conditions requiring intensive medical care.

What this trial studies

This randomized, parallel-group trial tests whether Transcutaneous Electrical Nerve Stimulation (TENS) can lessen oxytocin-driven uterine contractions during early breastfeeding. Participants are 124 women who recently delivered vaginally at term and are planning to breastfeed; they are randomly assigned to receive TENS during two consecutive feeds or to standard pain care. The TENS setup uses electrodes on the lower abdomen and sacral region, delivering a defined electrical pattern during feeding. Pain is measured on a 0–10 scale to compare peak pain between groups, with safety monitored throughout. The study aims to determine if TENS can provide a non-pharmacologic option for pain relief in the immediate postpartum period.

Why it matters

Potential benefit: If successful, TENS could provide a safe, low-cost alternative to medications for postpartum uterine pain during breastfeeding.

How similar studies have gone: Previous studies have explored TENS for various pain contexts; the effectiveness for postpartum uterine pain during breastfeeding remains to be established.
