It has been shown that regular ES of the denervated muscle fibers will suppress the chemical mediators required for the reconnection of the axon twig with the motor endplate on the muscle as well as reduce the random electrical activity of the orphaned muscle fibers [fibrillation] which is thought to be a signal for sprouting of the remaining healthy motor nerve.
All these medicines may cause sedation as a side effect. In spinal cord injury, for example, there is an injury to the spinal cord with a zone of injury in which the motor nerve cells in the cord may be destroyed. This nerve carries motor fibers to the muscles of facial expression.
