Anorectal Manometry

Anorectal Manometry

Anorectal manometry is a diagnostic procedure that measures muscle tone of the sphincters and other muscles within the anus and rectum. The procedure is conducted to gain a better understanding of the causes behind symptoms of chronic constipation and fecal incontinence (leaking of stool).

The test involves the insertion of a small, flexible probe into your rectum while you are lying on a couch. You may be asked at various times to relax or squeeze your rectal muscles, or to push down as if having a bowel movement. The test typically takes approximately 30 minutes.

Through the use of Anorectal Manometry, information can be gathered regarding:


  • Coordination of the rectal and anal muscles
  • Reflex action of the rectal and anal muscles
  • Sensation within the rectum
  • Strength and weakness of the anal and rectal muscles


A very effective treatment for constipation and fecal incontinence is biofeedback training.
