The best time to recover the pelvic floor muscles after delivery is within 42 days after delivery, the sooner the better. The pelvic floor muscles and fascia are congested and edematous after delivery, which may damage the supporting tissues of the pelvic floor, mainly due to obstructed labor, prolonged second stage of labor, oversized fetus, forceps assisted delivery and emergency delivery. The damage to the pelvic floor muscles during delivery is often characterized by extreme stretching and stretching, or even rupture damage, and damage to the pelvic floor nerves can also occur. If you participate in heavy physical labor too early after delivery, it will affect the recovery of pelvic floor tissue tone. Early pelvic floor rehabilitation training is recommended after delivery to reduce the incidence of pelvic floor dysfunctional diseases. Women who have a normal delivery and are in good condition can get up and do light activities 6-12 hours after delivery, and can start pelvic floor rehabilitation training on the second day after delivery under the guidance of a doctor. The rehabilitation training of pelvic floor muscles includes leg extension exercise, sit-ups, gluteal muscle exercise, lumbar muscle rotation exercise, pelvic twisting exercise, knee-chest position, etc., which are recommended to be performed under the guidance of professional doctors.
