Radiofrequency diathermy for postpartum abdominal muscle separation

Official title: Acute Effects of Radiofrequency Diathermy in Postpartum Women With Diastasis Abdominis

Run by University of Valencia · NCT07419399 · Data updated 2026-11-12

This test will see if a single session of radiofrequency diathermy changes pain sensitivity and tissue elasticity in postpartum women with or without rectus abdominis diastasis.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are postpartum women aged 20–45, 6 months to 1 year after delivery, with BMI 18.5–29.9 kg/m2, either with pathological RAD (inter-rectus distance >2.2 cm) or without RAD, and without prior abdominal surgery or chronic pain.

Probably not a fit

Women with cesarean deliveries, prior abdominal wall surgery, chronic pain diagnoses, or those outside the specified age, BMI, or postpartum windows are not eligible and are unlikely to benefit from this protocol's findings.

What this trial studies

This is a randomized, sham-controlled experiment enrolling 48 postpartum women, half with pathological rectus abdominis diastasis (RAD) and half without. Participants will be randomly assigned within their group to receive a single session of active radiofrequency diathermy (RFD) or a sham RFD, with measurements taken at baseline, immediately after treatment, and 20 minutes later. Primary measures are pressure pain threshold, superficial thermal sensitivity, and tissue elasticity to capture acute tissue responses. The trial is single-center and designed to detect immediate physiological differences between treated and sham groups across RAD status.

Why it matters

Potential benefit: If successful, the trial could show that RFD produces immediate, measurable changes in tissue sensitivity and elasticity that might guide non-surgical postpartum care.

How similar studies have gone: Radiofrequency diathermy has shown tissue-modulating effects in other musculoskeletal settings, but its acute effects specifically on postpartum rectus diastasis are largely untested.
