The best time to recover from poor pelvic floor muscle strength after childbirth is generally from 42 days to about 3 months after childbirth. Since the pelvic organs have not yet returned to their prenatal state within 42 days after delivery, and the ligaments and fascia are not yet relaxed, attention should be paid to rest during this period to allow the pelvic organs to recover in time, especially the uterus. If you do pelvic floor muscle recovery training during this period, it may affect the recovery of the pelvic organs, prone to sagging of the organs, so it is better to do pelvic floor muscle recovery training after 42 days after delivery. However, if the postpartum period is too long, the possibility of pelvic floor muscle recovery will become smaller and smaller, so try to do pelvic floor rehabilitation training within 3 months after delivery. Almost all pregnant women will have symptoms such as pelvic floor muscle relaxation and muscle strength deterioration after delivery. It is recommended to carry out pelvic floor muscle recovery training under the professional guidance of a rehabilitation physician at an appropriate time, and if necessary, use electrical stimulation, magnetic stimulation and other auxiliary treatments at the same time.
