Influence of pelvic floor muscle training alone or as part of a general physical activity program during pregnancy on urinary incontinence, episiotomy and third‐ or fourth‐degree perineal tear: Systematic review and meta‐analysis of randomized clinical trials

Abstract

AbstractIntroductionThe complex process of pregnancy and childbirth significantly influences the well‐being of both mother and child. Today all pregnant women without medical contraindications are recommended to start or continue regular aerobic and strength training for at least 150 min per week to prevent pregnancy‐related diseases and conditions. Urinary incontinence in pregnancy, episiotomy and third‐ or fourth‐degree perineal tear during labor can greatly impact womens’ health, quality of life and ability to be physically active. The aim of this study was to examine the efficacy of pelvic floor muscle training (PFMT) during pregnancy in the prevention of urinary incontinence, episiotomy, and third‐ or fourth‐degree perineal tear.Material and methodsA systematic review and meta‐analysis (CRD42022370600) was performed. Only randomized clinical trials published between 2010 and 2023 were included. The following databases were examined: EBSCO (including Academic Search Premier, Education Resources Information Center, MEDLINE, SPORTDiscus and OpenDissertations databases), Clinicaltrials.gov, Web of Science, Scopus, Cochrane Database of Systematic Reviews and Physiotherapy Evidence Database (PEDro). Three meta‐analyses to investigate the effect of PFMT exclusively or implemented as a section within a physical activity program during pregnancy on urinary incontinence, episiotomy, and third‐ or fourth‐degree perineal tear were conducted.ResultsThirty studies were analyzed (N = 6691). An effective preventive action of PFMT was found for urinary incontinence (z = 3.46; p < 0.0005; relative risk [RR] = 0.72, 95% confidence interval [CI]: 0.59, 0.87, I2 = 59%) and third‐ or fourth‐degree perineal tear (z = 2.89; p = 0.004; RR = 0.50, 95% CI: 0.31, 0.80, I2 = 48%) but not for episiotomy (z = 0.80; p = 0.42; RR = 0.95, 95% CI: 0.85, 1.07, I2 = 75%).ConclusionsPFMT during pregnancy proves to be an effective preventive intervention for reducing the risk of urinary incontinence and the occurrence of third‐ or fourth‐degree perineal tears. These findings highlight the importance of incorporating PFMT into antenatal care and training programs to improve maternal well‐being and overall childbirth outcomes.
