Study on the efficiency of electric stimulation of the pelvic floor

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.
