Anorectal manometry (ARM) 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, and to support a definitive diagnosis of dyssynergic defecation.
The test involves the insertion of a small, flexible probe into your rectum while you are lying on a table. 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 to one hour.
Through the use of ARM, 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
