Description

Technical Field

[0002] ] The pelvic floor muscles include the levator ani muscles, anal sphincter muscles, and obturator muscles. The pelvic floor muscles do not refer to a single muscle, but a group of muscles. It is like an elastic hammock that supports the uterus, bladder and other pelvic organs. Pregnancy, childbirth, and age are all causes of the hammock becoming loose, resulting in symptoms such as stress urinary incontinence when laughing or coughing, and vaginal relaxation. Similarly, when the muscle tension is high, it becomes very tight, and pelvic floor spasms, sexual pain, and dysuria are common symptoms. Pelvic floor dysfunction is a common and highly prevalent disease for women, and has become one of the chronic diseases that threaten women's health and quality of life. In addition to medical consultations and gynecological examinations, the muscle surface electromyography, pressure and other information of type I fibers and type II fibers are usually collected and analyzed by software to assist in the diagnosis or differential diagnosis of pelvic floor dysfunction and evaluate the treatment effect. The principle of rehabilitation is usually to reduce muscle tension first and then increase muscle strength.
