Some data show that about 45% of married women in China have pelvic floor dysfunction and 90% have poor quality of sexual life, so as women should pay attention to pelvic floor rehabilitation. Clinical medicine believes that pelvic floor muscle testing and rehabilitation should be performed when a woman returns to the hospital for a routine physical examination 42 days after giving birth. If the damaged pelvic floor muscles do not recover in time, vaginal looseness, unsatisfactory sex life, abdominal cramps, back pain, constipation, frequent urination and other discomforts may occur. The above phenomena will be more serious when entering menopause, and even pelvic organ prolapse will occur, which will seriously affect women’s health and quality of life. The pelvic floor muscle rehabilitation training not only helps women to regain their figure, but more importantly, the targeted training of the eight pelvic floor muscles after 42 days postpartum can reduce bladder prolapse and uterine prolapse and minimize the possibility of menopausal incontinence due to childbirth. In addition, the immediate effect of postpartum pelvic floor muscle rehabilitation is the treatment of postpartum vaginal laxity in order to improve the quality of sexual life of couples after childbirth. Pelvic floor muscle rehabilitation exercises are gradually being accepted for their non-invasive, less painful, safe and effective advantages.
