Study 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.

Inclusion Criteria: * Age between 20 and 45 years old. * BMI between 18.5 and 29.9 kg/mw. * Postpartum period between 6 months and 1 year Additionally, in the group of women with RAD, pathological RAD will be defined as an inter-rectus distance greater than 2.2 cm (measured 3 cm above the navel), according to the criteria of Beer et al. (2009) Exclusion Criteria: * Previous surgeries involving the abdominal wall. * Cesarean deliveries. * Women diagnosed with chronic pain

Primary outcome measure(s)

  • Pressure pain threshold — Baseline, immediately after the intervention and 20 minutes after the intervention.
    The pressure pain threshold will be measured using an algometer by applying progressive force to a supraumbilical point (three centimetres above the navel, at the lateral border of the rectus abdominis on the dominant side) until the participant reports pain. A higher value indicates a higher pain threshold.
  • Superficial thermal sensitivity — Baseline, immediately after the interventino and 20 minutes after the intervention
    Superficial thermal sensitivity will be assessed using the Thermal Visual Analogue Scale. For this, the capacitive electrode will be placed over the rectus abdominis on both sides for 30 seconds. Participants will then rate their thermal sensation on a scale from 0 (no heat) to 10 (maximum tolerable heat).
  • Tissue elasticity — Baseline, immediately after the interventino and 20 minutes after the intervention
    The MyotonPRO® myometer will be used to measure tissue elasticity over the rectus abdominis on both sides. Higher values indicate greater stiffness and lower tissue elasticity.
