There are different degrees of relaxation of the pelvic floor muscles and different symptoms. Some particularly severe patients may have severe urinary incontinence, severe uterine prolapse, some are in the third or fourth degree of prolapse, and some are very severe moderate to severe urinary incontinence, which may be more serious. Some mild patients may cough, sneeze, do strenuous exercise before mild leakage of urine, if usually walking, talking may not be a problem, this may be not so serious. So the severity of this is not easy to say, is based on the patient’s symptoms, the degree of injury to determine the severity of the complaints, generally there is no pelvic floor muscle relaxation serious or not this kind of statement, but rather is the patient’s symptoms, the degree of disease is not the same, the performance of the symptoms may not be the same, and the severity is not the same. Pelvic floor muscles have several main roles, the first is to support, maintain the whole pelvic floor muscles a kind of tension, if there is a problem, may show a kind of prolapse, there are rectal prolapse, uterine prolapse, and vaginal anterior and posterior wall of the prolapse. The patient’s class II muscles are primarily fast-acting, and fast-acting can be during running, during exercise, or during sexual intercourse, and the class II muscles are involved in the whole process, and if there are problems, there can be problems associated with that, including sexual dissatisfaction and urinary incontinence.
