Figure 5: Illustration of the pressures (a), stresses (b), and strains (c) at the contraction threshold and at the maximum contraction in the groups. Threshold and maximal amplitude of pressures and stresses increased, and strain decreased as function of the obstruction period during ramp distension. Significant differences were found after 4 days of obstruction compared with normal and sham-obstructed controls ( , ).
