Description of intervention(s) / exposure
Patients will be given a test of diastasis recti abdominis (DRA) 3rd postpartal day, after 6 weeks, 6 months and 12 months after delivery. The patients will mark the pain place on the body chart.
The patients will be tested in a standardised supine crock-lying position with instruction to perform an abdominal crunch till the shoulderblades were off the bed.The interrectus distance will be palpated using finger widths, just above umbilicus, 4.5 cm above and 4.5 cm below the umbilicus. DRA will be diagnosed as present if the palpated separation at any of the 3 mentioned locations along the linea alba will be <2 finger widths. The test will be performed by physiotherapists and it will take 5 minutes.

Statistical methods / analysis
For the incidence of diastasis recti abdominis after cesarean section it will be used calculate the frequency. To determine the significance of the conection in frequencies would be used chi aquared test. The corelation between the pain and diastasis recti abdominis will be determinated to Pearson's correlation coefficient. In interpreting the results statistically significant would be the value of P <0.05.

Summary
Brief summary
Diastasis recti abdominis (DRA) is defined as a separation of the two muscle bellies of rectus abdominis. Etiology of DRA is unknown, but the following causes are assumed: a constant mechanical load on the abdominal wall due to fetal growth resulting in stretching and weakness of abdominal muscles, then hormonal and consequent
changes in the functional capacity of abdominal muscles during pregnancy which after
birth contribute to the development of DRA. It often results in difficulties in daily activities that require increased intraabdominal pressure (eg defect, urination, vomiting, etc.). DRA may change posture and give more back strain due to reduced strength and function, leading to low back pain while larger separations can result to the hernia in the abdominal wall.
