Study summary

his study aims to evaluate the effect of an exercise program in postpartum women with diastasis recti, defined as an inter-rectus distance greater than 2 cm at any of three ultrasound measurement points . Participants will be divided into two groups: an intervention group that will follow a 6-week exercise program and a control group that will receive usual care.

Ultrasound assessment of the linea alba will be performed before the intervention and after 6 weeks. The main outcomes will be inter-rectus distance and the stiffness of the linea alba measured using shear wave elastography, along with obstetric and personal clinical variables. Participants will be recruited from primary care centers in the Community of Madrid through midwives during postpartum consultations.

Read the detailed description

In this study, the effect of an exercise program on postpartum women with diastasis will be evaluated. Diastasis will be defined as an inter-rectus distance greater than 2 cm at any of the points assessed by ultrasound (5 cm above the navel, at the level of the navel, and 2 cm below the navel).

Participants will be divided into two groups: one group will receive an exercise program for 6 weeks, while the other group will serve as the control group, receiving usual care. An ultrasound assessment of the linea alba will be performed before the start of the study and after 6 weeks.

The main variables evaluated will be inter-rectus distance and the stiffness of the linea alba measured by shear wave elastography, in addition to obstetric and personal variables obtained from the medical history. Participants will be recruited from primary care centers in the Community of Madrid through midwives during postpartum consultations.

  • Adult woman (> 18 years old)
  • Women who agreed to participate and provided written
  • Women between 6 and 12 weeks postpartum at the time of recruitment.

Exclusion criteria

Exclusion Criteria:

  • History of previous abdominal surgery ( except cesarean section)
  • Presence of abdominal or umbilical hernias
  • Current pregnancy
  • Neuromuscular or systemic conditions affectinf the abdominal wall
  • Active infections
  • Any condition that could intervere with the correct execution of the measurement protocol.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Exercise group

    This group follows an exercise program for 6 weeks.

    Other: Exercise program

  • No intervention
    Control group

    This group does not follow the exercise program and continues with their usual care through the public healthcare system, which does not include any intervention for diastasis.

Interventions

  • OtherExercise program

    Structured therapeutic exercise program aimed at restoring functional integritu of the abdominal-lumbo-pelvic complex over a six week period. The exercise program was based on activation of the transversus abdominis muscle, synergistic co-activation with the pelvic floor muscles, breathing re-education, and the integration of hypopressive abdominal exercises.

    Also known as: exercise therapy

What researchers measure

Primary outcomes

  1. Interrectus distance

    This group does not follow the exercise program and continues with their usual care through the public healthcare system, which does not include any intervention for diastasis.

    Time frame: From enrollment to the end of treatment at 6 weeks.

  2. Stiffness of the linea Alba

    CopilotThe stiffness of the linea alba will be measured at three points (5 cm above the navel, at the level of the navel, and 2 cm below the navel) using shear wave elastography.

    Time frame: From enrollment to the end of treatment at 6 weeks.
