Functional electrical stimulation for reconstruction of neoanal function

For reconstructing a neoanal function, it is necessary to convert the properties of the transposed gracilis muscle to the properties suitable for the neoanal sphincter. The muscle which was converted to a fatigue resistant form after long-term electrical stimulation can maintain contraction. Much strong stimulation causes muscle fatigue, so it is necessary to regulate neoanal pressure with moderate stimulation. Using rabbit models, the effects of long-term electrical stimulation for converting the muscle to a fatigue resistant form are discussed. An electrical stimulation system to regulate neoanal pressure is proposed
