The continuous electric stimulation of the anal sphincter leads to the onset of a very quick fatigue of the muscle, with a progressive decrease of the amplitude of contraction after 15 min of stimulation. Under the same experimental conditions intermittent stimulation leads to a sustained contraction amplitude. Ts and Tr combinations that can give efficiency rates of contraction above 80 per cent were defined. The results of this study could be applied when intermittent electric stimulation of the pelvic floor is indicated for the treatment of anal or urinary incontinence.
对肛门括约肌进行持续电刺激会导致肌肉很快出现疲劳，在刺激15分钟后收缩幅度逐渐减小。在相同实验条件下，间歇性刺激会使收缩幅度保持稳定。确定了能使收缩效率达到80%以上的Ts和Tr组合。当需要通过间歇性电刺激盆底来治疗肛门失禁或尿失禁时，本研究结果可提供参考。
