2. Figure 1
Comparison of colonic compliance (Pr50) among categories. Among patients without DD, Pr50 was lower in STC than NTC. However, among patients with DD, Pr50 was comparable in DD-NTC and DD-STC. The horizontal line is the 10th percentile value in healthy subjects.

3. Figure 2
Normal fasting, postprandial and postneostigmine tonic, and phasic colonic motor activity in a patient with STC. Observe reduced balloon volume, reflecting increased colonic tone, after a meal and after neostigmine. Manometry showed increased phasic pressure activity in the sigmoid colon after a meal and also in the descending colon after neostigmine. The principal component analysis revealed a high score for factor 2.

Impaired colonic tonic contractile responses to a meal and neostigmine in a patient with STC. In contrast, manometry revealed increased fasting and postprandial phasic pressure activity. The principal component analysis revealed a high score for factor 1.
