Prevalence of diastasis m. rectus abdominis and pelvic floor muscle dysfunction in postpartum women.

Objective: The aim of this study was to determine the prevalence of Diastasis of the rectus abdominis muscles (DRAM) and pelvic floor muscle dysfunction (PFMD) in postpartum women. Design: The observational prospective study.

Material: 150 of 180 women (83.3 %) from 6 weeks to 6 months postpartum, with a mean age of 33.1 years.

Methods: For diastasis examination, inter recti distance (IRD) was measured by a linear 2D ultrasound probe, 4.5 cm above the navel, in its area and 4.5 cm below the navel when lying on the back at rest and under a load test. The degree of DRAM was classified into four grades. Urinary leakage symptoms were assessed by the International Incontinence Consultation Questionnaire (ICIQ - UI SF).

Results: The first degree of diastasis during the load test was 38.1 % above the navel, 36.4 % in the navel area, and 23.7 % below the navel. The second degree of diastasis with load was 28.8 % above the navel, 21.2 % in the navel area, and 10.2 % below the navel. PFMD showed 31.3 % of women with mild symptoms of SUI, 32.2 % of women with grade 1 cystocele.

Conclusion: The average IRD distance at rest and during the load test confirmed the first grade of DRAM out of four degrees of severity. Moderate and medium DRAM occurred according to location in an average of one-third of the cases. The highest percentage of DRAM was above the navel, and the lowest percentage below the navel. PFMD was detected in an average of one-third of cases. It is important to monitor these parameters with a view to improving the quality of life index in the future (Tab. 5, Ref. 22).
