The relevance of several clinical and psychophysiological variables in the dyssynergic defecation in elderly subjects was investigated in this study. To accomplish this, 30 elderly subjects (10 without anorectal disorders, 10 with chronic constipation and 10 with dyssynergic defecation) were repeatedly assessed once per week for 4 weeks, with the following measures being collected at each session: EMG-activity (µV) of the external anal sphincter (at rest, during squeezing, and during straining to defecate), stool frequency, difficulty defecation level, pain grade during defecation, and satisfaction level after evacuation. A 3 (group) × 4 (sessions) mixed-measures MANOVA revealed a significant main effect for group (Wilks’s lambda = 0.006; F = 28.45; p < 0.01), but not for sessions (Wilks’s lambda = 0.874; F = 0.94; p > 0.05) or for the group x sessions interaction (Wilks’s lambda = 0.811; F = 1.45; p > 0.05).

Abstract

The relevance of several clinical and psychophysiological variables in the dyssynergic defecation in elderly subjects was investigated in this study. To accomplish this, 30 elderly subjects (10 without anorectal disorders, 10 with chronic constipation and 10 with dyssynergic defecation) were repeatedly assessed once per week for 4 weeks, with the following measures being collected at each session: EMG-activity (µV) of the external anal sphincter (at rest, during squeezing, and during straining to defecate), stool frequency, difficulty defecation level, pain grade during defecation, and satisfaction level after evacuation. A 3 (group) × 4 (sessions) mixed-measures MANOVA revealed a significant main effect for group (Wilks’s lambda = 0.006; F = 28.45; p < 0.01), but not for sessions (Wilks’s lambda = 0.874; F = 0.94; p > 0.05) or for the group x sessions interaction (Wilks’s lambda = 0.811; F = 1.45; p > 0.05). One-way ANOVA and Scheffé’s posthoc tests were used to isolate the differences between the groups with respect to the seven different measures. These analysis showed significant differences between the groups on all four clinical variables but only for one psychophysiological variable, EMG-activity during straining to defecate. Significant differences were evidenced between all pairs examined for the difficulty defecation level and pain grade. The complete results of these analysis are presented and the conclusions drawn from them are discussed.
