The so-called postpartum repair, that is, the recovery of postpartum pelvis, also includes the recovery of pelvic floor muscles. Postpartum pelvic deformation often leads to the widening of hip bone, so it is necessary to bind abdomen specially to promote pelvic repair. For postpartum women, anal contraction exercise or special pelvic floor muscle rehabilitation treatment is needed for postpartum repair because it will lead to vaginal wall bulging. For postpartum women, it is generally suggested that pelvic repair is necessary, whether it is natural delivery or caesarean section. This is because postpartum women's pelvis will be deformed and relaxed. At this time, pelvic repair can be done to promote the stereotyped recovery of pelvis. For women with loose abdomen, the abdomen can also be more compact through repair.
