[0002] During pregnancy, due to the growth of the fetus, the uterus enlarges and compresses the pelvic floor muscles. The excessive pressure and traction during childbirth can also make the pelvic floor muscles loose and weak. The weakening of the pelvic floor muscle function in women can lead to pelvic floor disorders such as urinary incontinence, organ prolapse, vaginal relaxation, and sexual intercourse pain, seriously affecting the physical and mental health and quality of sexual life of women. At present, the treatment is mainly carried out through a pelvic floor muscle biofeedback therapeutic apparatus. The pelvic floor muscle biofeedback therapeutic apparatus is mainly used for the treatment of diseases related to pelvic floor muscle dysfunction. Through the principle of biofeedback, the activities and tensions of the pelvic floor muscles are converted into visible graphs and data, enabling patients and doctors to intuitively understand the condition of the pelvic floor muscles.
