The muscles, ligaments and fascia in the female pelvic floor shape the form and function of the pelvic floor organs, and the blood vessels and nerves play a role of nutrition, dominance and regulation. The normal pelvic floor function depends on the complex interactions between the complete muscles, connective tissue and nerve distribution. A large number of studies have shown that the changes in the pelvic floor and even injury of pregnancy and childbirth are closely related to the occurrence of pelvic floor dysfunction diseases. During pregnancy, mechanical action and changes in hormones lead to the remodeling of the pelvic floor structure, and the intrapartum overstretch causes pelvic floor muscles, connective tissue and nerves injury. These changes have a natural tendency to recover after delivery. And the recovery relatives with the occurrence of postpartum pelvic floor dysfunction or forwards, so overall effective pelvic floor rehabilitation treatment are increasingly concerned by all of us.
