Generally pregnant women can do pelvic floor muscle recovery training 42 days after delivery. Pregnancy and childbirth are special physiological processes for women, the hormone level of the female organism will change a lot during this stage, and the enlarged uterus presses the pelvic floor muscle, resulting in the weakening of the function of the pelvic floor muscle, which increases the risk of pelvic organ prolapse, and causes serious damage to the pelvic floor tissues. Postpartum pelvic floor muscle training belongs to functional rehabilitation training. Pelvic floor muscle exercise can help mothers to consciously control their pelvic floor muscles and reasonably adjust the pelvic floor muscle activities to better repair the pelvic floor muscles and arouse the muscle proprioceptors, so as to improve the tightness of the vagina and the pelvic floor function of the mothers after delivery, and to effectively prevent pelvic floor dysfunction. In the early postpartum period, mothers are still physically and mentally exhausted, and some mothers are not yet ready for rehabilitation training, so the effect may be greatly reduced if rehabilitation training is carried out too early at this time. In addition, in the early postpartum period, the mother is still in a state of vulvar and vaginal congestion, and rehabilitation training at this time may cause vaginal bleeding, vaginitis and other problems. If the uterus has recovered well and there is no infection, the pelvic floor training can be carried out at 42 days after delivery. From 42 days to half a year after delivery is the golden time for pelvic floor muscle recovery. Grasping this golden time and insisting on doing the correct pelvic floor muscle training can help the pelvic floor muscle recover better and faster.
