Abstract:Objective To monitor and evaluate postpartum women's pelvic floor function, and to analyze the electrophysiological changes of pelvic floor muscles and their influencing factors in postpartum women. Methods The health records and electromyogram (EMG) results of pelvic floor in 3,600 puerpera undergoing 42-day postpartum health check-ups from January 2014 to December 2015 were retrospectively analyzed. Results There were 3,086 abnormal EMG results, accounting for 85.72%. Among them, the incidence of overactivity was the highest. Older mothers, large fetuses, pluripara and those who had vaginal delivery had higher incidences of pelvic floor myoelectrical abnormalities. Conclusions Postpartum pelvic floor myoelectrical changes are related to maternal age, fetal size, pregnancy times, delivery methods, etc. Attention must be paid to postpartum function health care and rehabilitation of pelvic floor in these high-risk mothers. And active postpartum self-exercise of the pelvic floor muscles is conducive to the restoration of pelvic floor function.
