1. Anorectal manometry. A pressure probe is placed in the rectum and anus to assesses the pressure activity.

2. Defecography. Barium is placed in the rectum and the patient bears down during videofluoroscopic imaging.

3. Electromyography An electrode is placed in the external anal sphincter and myoelectrical activity is measured.

4. Simulated defecation. A silicone-filled artificial stool is placed in the rectum. Difficulty in expelling the artificial stool indicates obstructive defecation.
