Results After treatment, the total efficacies in the control and treatment groups were 87.80% and 95.12%, respectively, and there were differences between two groups (P<0.05). After treatment, scores of defecation degree, fecal character, and defecation time in two groups were significantly decreased, and the difference was statistically significant in the same group (P<0.05). After treatment, the decreased degrees of scores in the treatment group were significantly better than those in the control group, with significant difference between two groups (P<0.05).
