Biofeedback makes it easier to isolate body activities. Because problems of the anorectal area are difficult to see visually, we provide feedback using a computer monitor and a pressure device. This lets a patient see and correct the problem using specific training exercises. Biofeedback is used to identify:
- Anismus, which is inappropriate movement of pelvic muscles that prevents stool from exiting the body
- Incontinence, which is the inability to control evacuation of the stool
- Rectal hypersensitivity and hyposensitivity, which is respectively excessive sensitivity of the rectal area and insensitivity of the rectal area
You should consult with the physician who is ordering the study to learn what you should do or not do before your procedure.
