SECONDARY, CONTRACTION, VAGINA, URETHRA
The most medial muscle portion of the levator ani (LA) muscle borders the levator hiatus (LH), an opening in the pelvic floor allowing the passage of the urethra, rectum, and the vagina [Tomographic ultrasound imaging of the levator ani (Early active rehabilitation is standard treatment after musculo-skeletal injury within sports physical therapy, and training is believed to be important in speeding up tissue healing (repair and remodeling) [The main aim of the present study was to investigate whether PFMT early after vaginal delivery enhances tissue healing, seen as a reduction in number of complete LA avulsions detected via ultrasound (primary outcome), and a reduction of the absolute value of the LH area measured at rest, and during maximal PFM contraction and Valsalva (secondary outcomes). An added aim was to explore whether women with complete LA avulsion have a larger LH area during a PFM contraction than women without such major tears at baseline and after the intervention ended.
