Brief Summary:
The main purpose of this study was to observe the pelvic floor muscle strength abnormalities of cesarean section and vaginal delivery at different time points within six months after delivery without any intervention. It was a prospective observational study, and the main study population was healthy postpartum women. Regular follow-up was conducted at 6 weeks, 9 weeks, 3 months, 4 months, 5 months and 6 months postpartum. The follow-ups included gynecological examination, pelvic floor electrophysiological indexes (category I and II muscle fiber strength and fatigue), questionnaire (ICI- Q-SF, OABSS, UDI-6), and pelvic floor ultrasound. The incidence of pelvic floor muscle strength abnormality at different postpartum time points was statistically analyzed, the high-risk factors of postpartum pelvic floor function abnormality caused by pregnancy and delivery were analyzed, and the general rules of the natural development of pelvic floor function were observed.
