Interrectal Distance Diastasis Recti Dimensions of the Muscles of the Lateral Abdominal Wall | Other: Ultrasound |
- Purpose of the study is the assessment of interrectal distance and dimensions of the muscles of the lateral abdominal wall in pregnant and non-pregnant women
- Assessment via ultrasound measurement transabdominally
- 3 groups of participants: 1.) 20 pregnant women, who have never been pregnant before; 2.) 40 pregnant women with their first pregnancy, followed over the course of pregnancy; 3.) 20 women1-5 days after delivery (10 after spontaneous delivery, 10 after planned cesarean section)
