Pelvic floor rehabilitation is a type of rehabilitation that promotes the recovery of nerves and muscles damaged during pregnancy and childbirth, thus improving the long-term pelvic floor condition, and is a relatively rapidly developing field of rehabilitation in recent years. Pelvic floor rehabilitation can reduce the chance of pelvic floor dysfunctional disorders due to anatomical changes and aging. Studies have shown that pelvic floor training during pregnancy can reduce the incidence of pelvic floor dysfunction in the first 3 months after delivery, and postpartum rehabilitation can significantly reduce the incidence of pelvic floor dysfunctional disorders in the 6-12 months after delivery. Pregnancy and childbirth are important factors in the development of pelvic floor dysfunctional disorders, and the postpartum period happens to be a special favorable period for the prevention and treatment of pelvic floor dysfunctional disorders. In general, women who have cleared their dew after 42 days after delivery can start treatment related to pelvic floor rehabilitation. In order to prevent the occurrence of pelvic floor dysfunctional disorders, it is recommended that all postpartum women routinely undergo pelvic floor rehabilitation.
