The discharges arise from the peripheral aspects of regenerating nerves, and clinically impart a nearly continuous undulation of the body surface overlying the muscle. (Adams et al., Principles of Neurology, 6th ed, p1491),NCI: A disorder characterized by involuntary and irregular muscle contractions not associated with muscle weakness or atrophy. It most often affects facial muscles. It may be localized or generalized.
