About this study

Pregnancy and childbirth cause corporal changes in women, altering the structure and function of the abdominal and pelvic floor muscles. The distension of the muscular tissue and the possible diastasis recti can alter the performance of the abdominal musculature in the control of intra-abdominal pressure and the lumbo-pelvic stabilization in postpartum term. Abdominal exercise is highly recommended to restore these changes but there is not enough evidence about the effects of exercise modalities.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Primiparous women
  • Normal not operative delivery
  • One child delivery

Exclusion criteria

  • Two or more previous gestation
  • Previous abdominal surgery
  • Systemic disease, neurologic or metabolic disease

Treatment and study plan

Physical therapy intervention

Other

Primiparous women start a physical therapy intervention in week 6 after normal one-child delivery, based on abdominal and pelvic floor exercises, education and behavior advices. Abdominal muscle condition and activation are measured by transabdominal ultrasound and surface electromiography. This group is going to be examined after treatment and 6 and 12 months after treatment.

Primary outcomes

  1. Inter-rectus distance (mm)

    Time frame: 1 day

    Inter-rectus abdominis distance in mm in rest position.

Secondary outcomes

  1. Cross-sectional area (mm)

    Time frame: 1 day

    Cross-sectional area of rectus abdominis, external oblique, internal oblique and transversus abdominis in rest position.

  2. Neuromuscular activity (mV)

    Time frame: 1 day

    Neuromuscular activity (mV) of rectus abdominis, external oblique and internal oblique + transversus abdominis in rest position.

  3. Inter-rectus distance (mm) during an hypopressive exercise

    Time frame: 1 day

    Inter-rectus distance (mm) during an hypopressive exercise performance in supine position.
