Use of a Squatting Assist Device in Patients With Constipation

November 5, 2019


Western style toilets require a person to sit on the toilet instead of a squatting position, usually required in foreign countries. Some studies suggest the squatting position may be more optimal for helping bowel evacuation. This clinical trial studies the use of a footstool versus the use of a regular, sitting toilet for relieving constipation.


Study Information

The footstool is 7 inches tall to help mimic the squatting position of foreign toilets. The comparative device will be a 2 inch stool. Bowel movement frequency will be recorded to compare which of the devices is more effective for relieving constipation.
