Clinical significance: there are no particularly effective drugs for the treatment of functional pelvic floor disorders, and the use of biofeedback electrical stimulation is currently the most effective method and means recommended by the clinic! Biofeedback electrical stimulation technique: It is a natural therapy that uses microcurrent to stimulate specific muscle groups and applies functional training (muscle contraction and diastolic function) to improve and coordinate the functional state of local muscles and organs (contraction intensity, duration and sensitivity). Clinical applications: relief and resolution of defecation disorders such as chronic constipation, postoperative defecation dysfunction; anal incontinence such as anal sphincter injury, urge or neurogenic fecal incontinence; pelvic floor sensory abnormalities such as pelvic floor pain, pelvic floor muscle spasm, anal cramping; urinary incontinence, vulvar pain syndrome, uterine, bladder, vaginal prolapse, vaginal laxity, bladder overactivity, etc.
