Abstract: Objective The features was probed into by colonic electricity and motion in visceral hypersensitivity rat. Methods The experiment consists of the control series and the model series ,and the latter series were sensitized by intraperitoneal injection of chicken egg albumen．After two weeks, the colon spike potential 、slow wave and the colon contraction were written and the interdigestive myoelectric complex cycle，III phase times， spike potential and slow wave propagation rate、the average largesttest amplitude were observed，and the number of the contraction 、the index of contraction were noted. Result The IMC cycle and III phase times of model group prolongs （P<0.01），and spike potential propagation rate speeds up （p<0.05），and the largesttest amplitude increases （P<0.01）.The slow wave propagation rate speeds up （p<0.05） and the largesttest amplitude increases（P<0.01）. The number of the contraction increases （p<0.05）and the index of contraction grows（p<0.05）. Conclusion There are quite difference between model group and control group in electricity and motion of visceral hypersensitivity rat.
