Date Mar. 21, 1991.An appliance for electrically stimulating tissue contractions of a living organism has circuitry for applying a stimulation potential to the tissue region to be stimulated and for applying a reference potential circuitry for detecting to the body of the living organism, stimulated tissue contractions. Following stimulation the stimulated tissue contraction is measured by a bipolar electrode between two adjacent tissue regions, the stimulation potential applied being to at least one of these tissue regions for the purpose of stimulating a tissue contraction.
