A study was made of the defecatory sensation in 130 patients with normal rectums. By means of a specially designed balloon inserted into the rectum, determinations were made of intrarectal pressure, rectal diameter and rectal tension. The desire to defecate was correlated with the levels of these measurements. There was a progressive rise with age in the threshold for these factors. Rectal sensitivity to distention was lower in the constipated patients than in those who were not constipated.
