Postpartum mothers may have pelvic floor muscle relaxation and rectus abdominis separation at the same time after giving birth. It should be noted that the pelvic floor muscles must be repaired first during postpartum rehabilitation. As the fetus gradually grows during pregnancy, it will compress the pelvic floor muscles. The pelvic floor muscles are extremely stretched and their contraction ability decreases, resulting in relaxation. At the same time, the enlarged uterus during pregnancy will cause the abdominal wall to expand and extend, and the rectus abdominis will separate from the midline of the abdomen to both sides.
The pelvic floor muscles and the deep abdominal muscles are a whole. When the rectus abdominis muscles are separated and repaired, the abdominal pressure will increase, and the function of the pelvic floor muscles of the mother will decrease after delivery. If the pelvic floor muscles are weak, the abdominal muscles will be performed. Repair of rectus muscles will cause secondary damage to the pelvic floor muscles. Therefore, it is necessary to repair the rectus abdominis when the pelvic floor muscle strength is level three or above.
