Biofeedback is thought to be very effective as a treatment for constipation, incontinence and dyssynergic defecation. Biofeedback simply uses sensors and a computer to give you feedback about how your muscles and nerves are responding.

Most of the muscles of the pelvis surrounding the anus and rectum are under some degree of voluntary control. Thus, biofeedback training can teach patients with constipation, incontinence or pelvic floor dysfunction how to make their muscles work more normally and improve their ability to defecate. During ano-rectal biofeedback training, a pressure-sensing catheter is placed through the anus and into the rectum. Each time a patient contracts the muscles, the muscles generate a pressure that is sensed by the catheter and recorded on a screen. By watching the pressures on the screen and attempting to modify them, patients learn how to relax and contract the muscles more normally.

Specifically, you will be taught:


  • What is supposed to happen during the process of having a normal bowel movement.
  • How to relax pelvic floor muscles during the process of defecation.
  • How to improve your awareness of sensations regarding the need to have a bowel movement.
