Acute Effects of Radiofrequency Diathermy in Postpartum Women With Diastasis Abdominis

Sponsor

University of Valencia

Enrollment

48 participants

Start Date

Mar 30, 2026

Study Type

INTERVENTIONAL

Conditions

Postpartum Rectus Muscle Diastasis

Summary

This clinical trial aims to compare the immediate tissue response in postpartum women with and without rectus abdominis diastasis (RAD) after undergoing radiofrequency diathermy (RFD) treatment. The main question it seeks to answer is: Do postpartum women with and without RAD exhibit different acute tissue responses in terms of pressure pain threshold, superficial thermal sensitivity, and tissue elasticity? To determine whether there are differences in these acute tissue responses between the groups, researchers will compare RFD with a sham RFD intervention in postpartum women with and without RAD. Participants will receive one session of either RFD or a sham RFD intervention and will complete three assessments: one at baseline and two after the intervention, one immediately afterwards and one 20 minutes afterwards.
