Enhancement of Levator Ani Muscle Strength in Postpartum Women: The Impact of Pelvic Floor Muscle Training.

ABSTRACT

BACKGROUND Levator ani muscle injuries during vaginal childbirth can lead to pelvic organ prolapse (POP). Pelvic floor muscle training (PFMT) is an effective conservative approach to alleviate these symptoms. This study aimed to compare outcomes with and without 3 months of PFMT in 34 women with levator ani muscle injury following vaginal delivery. MATERIAL AND METHODS In a quasi-experimental study, 34 postpartum women were divided into 2 groups one received PFMT along with home-based materials and regular follow-ups, while the other served as the control. We measured basal tone and maximal levator ani muscle contraction using the Peritron perineometer and assessed changes after 3 months. RESULTS The basal tone and maximal contraction of the levator ani muscle significantly increased following a 3-month intervention period both in PFMT and control group (P=0.0001). The maximal contraction of the levator ani muscle after a 3-month intervention period was significantly higher in PFMT group compared with control group (36.59±1.45 vs 27.76±13.35, P=0.0001), respectively. A significant positive correlation was found between basal tone and maximal contraction (r=0.806, P=0.0001). CONCLUSIONS A 3-month PFMT program effectively increased levator ani muscle strength in postpartum women compared to those who did not undergo PFMT.
