Background/aim Diastasis recti abdominis (DRA) is defined as a separation of the 2 muscle bellies of rectus abdominis. To date there is scant knowledge on prevalence, risk factors, and consequences of the condition. The present study aimed to investigate the prevalence of DRA during pregnancy and post partum, presence of possible risk factors, and the occurrence of lumbopelvic pain among women with and without DRA. Methods This prospective cohort study followed 300 first-time pregnant women from pregnancy till 12 months post partum. Data were collected by electronic questionnaire and clinical examinations. DRA was defined as a palpated separation of ≥2 fingerbreadths either 4.5 cm above, at or 4.5 cm below the umbilicus. Women with and without DRA were compared with independent samples Students t-test and χ2/Fisher exact test, and OR with significance level >0.05. Results Prevalence of DRA was 33.1%, 60.0%, 45.4%, and 32.6% at gestation week 21, 6 weeks, 6 months and 12 months post partum, respectively. No difference in risk factors was found when comparing women with and without DRA. OR showed a greater likelihood for DRA among women reporting heavy lifting ≥20 times weekly (OR 2.18 95% CI 1.05 to 4.52). There was no difference in reported lumbopelvic pain (p=0.10) in women with and without DRA. Conclusions Prevalence of mild DRA was high both during pregnancy and after childbirth. Women with and without DRA reported the same amount of lumbopelvic pain 12 months post partum.

Background It has been suggested that women who are regular exercisers have a tighter pelvic floor and thereby have more difficulty during childbirth than non-exercising women. We investigated whether women exercising before and during pregnancy have a narrower levator hiatus (LH) area than their sedentary counterparts. We also studied whether regular exercise at gestational week 37 influences delivery outcome. Methods Cohort study of 274 nulliparous pregnant women assessed at mid-pregnancy and gestational week 37 by three-dimensional/four-dimensional transperineal ultrasonography of the LH area. Exercisers were defined as those exercising ≥30 min three times per week and non-exercisers as not exercising. Exercise data were collected via electronic questionnaire at mean gestational weeks 21 and 37. Labour and delivery outcomes were collected from the womens electronic medical birth records. Differences between exercisers and non-exercisers were analysed using independent sample t test or χ2 test. p Value was set to ≤0.05. Results At gestational week 37, exercisers had a significantly larger LH area than non-exercisers at rest and during PFM contraction (mean difference −1.6 cm2 (95% CI −3.0 to −0.3), p=0.02 and −1.1 cm2 (95% CI −2.0 to −0.1), p=0.04, respectively). No significant differences were found between exercisers and non-exercisers at week 37 in any labour or delivery outcomes. Conclusions The results of the present study do not support the hypothesis that women exercising regularly before or during pregnancy have a narrower LH area or more complicated childbirths than non-exercising women. Trial registration number ClinicalTrials.gov: NCT01045135.

Compare vaginal resting pressure (VRP), pelvic floor muscle (PFM) strength, and endurance in women with and without diastasis recti abdominis at gestational week 21 and at 6 weeks, 6 months, and 12 months postpartum. Furthermore, to compare prevalence of urinary incontinence (UI) and pelvic organ prolapse (POP) in the two groups at the same assessment points.

The aim of the present study was to compare vaginal resting pressure (VRP), pelvic floor muscle (PFM) strength and endurance, and prevalence of urinary incontinence (UI) at 6 weeks postpartum, in women with and without lateral or mediolateral episiotomy.

Abstract Background Diastasis recti abdominis affects a significant number of women during the prenatal and postnatal period. Objective The objective was to evaluate the effect of a postpartum training program on the prevalence of diastasis recti abdominis. Design The design was a secondary analysis of an assessor-masked randomized controlled trial. Methods One hundred seventy-five primiparous women (mean age = 29.8 ± 4.1 years) were randomized to an exercise or control group. The interrectus distance was palpated using finger widths, with a cutoff point for diastasis as ≥2 finger widths. Measures were taken 4.5 cm above, at, and 4.5 cm below the umbilicus. The 4-month intervention started 6 weeks postpartum and consisted of a weekly, supervised exercise class focusing on strength training of the pelvic floor muscles. In addition, the women were asked to perform daily pelvic floor muscle training at home. The control group received no intervention. Analyses were based on intention to treat. The Mantel-Haenszel test (relative risk [RR] ratio) and the chi-square test for independence were used to evaluate between-group differences on categorical data. Results At 6 weeks postpartum, 55.2% and 54.5% of the participants were diagnosed with diastasis in the intervention and control groups, respectively. No significant differences between groups in prevalence were found at baseline (RR: 1.01 [0.77–1.32]), at 6 months postpartum (RR: 0.99 [0.71–1.38]), or at 12 months postpartum (RR: 1.04 [0.73–1.49]). Limitations The interrecti distance was palpated using finger widths, and the sample included women with and without diastasis. Conclusions A weekly, postpartum, supervised exercise program, including strength training of the pelvic floor and abdominal muscles, in addition to daily home training of the pelvic floor muscles, did not reduce the prevalence of diastasis.

Background Female sexual dysfunction has been classified as sexual desire/interest disorder, arousal disorder, orgasmic disorder, and sexual pain disorder. It is complex but some of the symptoms are thought to be linked to the pelvic floor musculature. Physical therapy is suggested as one treatment option, but it is not known whether or how this may be effective.
