After having a baby, the pelvic floor and vagina are in a different state than they were during non-pregnancy. After pregnancy, because the uterus is slowly increasing in size, the enlarged uterus is a chronic compression of the pelvic floor due to gravity. This continuous compression causes damage to the muscles and fascia of the pelvis, and this damage is aggravated in the case of normal delivery. Therefore, the process of pregnancy and delivery can cause damage to the muscles and fascia of the pelvic floor as well as to the vagina. During the review after delivery, not only should a gynecological ultrasound be done to understand the recovery of the uterus, but a pelvic floor screening should also be done to determine the muscle strength of the pelvic floor, and the results should be used to guide the next step of pelvic floor rehabilitation treatment. Nowadays, pelvic floor rehabilitation in hospitals is getting more and more attention because people are paying more and more attention to improving their quality of life. This is because many women experience coughing and sneezing after childbirth, and some women experience unsatisfactory sex life, all of which can be treated by doing pelvic floor rehabilitation.
