The pelvic floor muscle is like a “net”, the urethra, bladder, vagina, uterus, rectum and other organs are suspended by this net, so as to maintain the normal position and exercise its function. After the birth of the mother should pay more attention to the pelvic floor muscle rehabilitation, women who have experienced October pregnancy, with the increase in the size of the fetus and the weight of the uterus, long-term pressure on the bottom of the pelvis, just like putting a heavy object on the rubber band for a long time, and so the weight removed, the rubber band is still difficult to restore to the previous state of elasticity, so whether it is a normal birth or a caesarean section, will make the pelvic floor muscle this “net “The pelvic floor muscles are damaged to varying degrees. Other women have a history of multiple births, poor childbirth history, family history, fat or thin, female ageing estrogen levels decline and other factors can also lead to muscle relaxation of the pelvic floor muscles, so that the pelvic floor muscles this network is damaged to varying degrees. Low pelvic floor muscle strength in women mainly manifests itself in vaginal laxity, decreased quality of sexual life, abdominal cramps, nocturnal urination, frequent urination, involuntary leakage of urine when abdominal pressure increases (e.g. coughing, sneezing, laughing), and constipation. Even if individual women do not have obvious symptoms after giving birth, as they age, especially after entering menopause, the estrogen level further decreases and different degrees of urinary incontinence, uterine prolapse, bladder prolapse, rectal prolapse or recurrent vaginitis and other diseases and poor quality of sexual life will occur. If the symptoms are not treated until they become obvious, it will be more difficult to treat and affect the efficacy. Therefore, it is recommended that postpartum mothers make pelvic floor rehabilitation a routine treatment. What is the pelvic floor muscle? It is a general term for the muscles of the pelvic floor, which consists of muscles and ligaments that close the pelvic outlet and carry and support the organs in the pelvic cavity. The physiological functions of the pelvic floor muscles include maintaining the normal anatomical position of the pelvic organs, participating in urinary control, participating in bowel control, maintaining vaginal tightness, and maintaining normal sexual function. 40-50% of women over the age of 30 have pelvic floor dysfunctional disorders, which are among the top five chronic diseases that affect the quality of human life. Timing of pelvic floor rehabilitation treatment: Maternal: 1. Start 42 days after delivery. 2 times a week, 48 hours between treatments, a course of 10-15 times the sooner you start treatment, the better, one year after delivery is the “golden time” for pelvic floor muscle function recovery. 2, non-maternal: women ≥ 30 years old or have symptoms of pelvic floor muscle damage, should be treated as early as possible. 2-3 times a week, 48 hours between sessions, a course of 15 sessions. Treatment methods for pelvic floor dysfunctional diseases: low-frequency electrical stimulation, electronic biofeedback, pelvic floor muscle rehabilitation machine training, pelvic floor rehabilitation exercise training. Electrical stimulation therapy role: arousal of proprioceptors, passive muscle exercise, inhibition of bladder forced urinary muscle contraction, analgesia, and promotion of local blood circulation. Biofeedback therapy: With the help of instruments, certain physiological functions of patients are traced; at the same time, they are converted into feedback information such as sound and light; so that patients learn to adjust the involuntary visceral functions and other somatic functions according to the feedback signals. To achieve the purpose of disease prevention and treatment.
