Defecation rate, the percentage of defecation rats during a given period. Bold type, the average of the four time points. *p < 0.05, comparison between SCI Rats with S and SCI Rats; **p < 0.05, between SCI Rats with S and Intact rats; †p < 0.05, between SCI Rats and Intact Rats; ‡p < 0.05, between Rats with S and SCI Rats; §P < 0.05, between Rats with S and SCI Rats with S (Chi-square test or two-way ANOVA).
