Movement disorders induced by peripheral trauma.
Movement disorders induced by central nervous system trauma are well recognized. However, over the last few years, attention has been drawn to the role of peripherally induced movement disorders. We describe three patients presenting respectively dystonia, tremor and choreoathetosis associated with tremor and dystonia of the body parts previously exposed to traumatic injuries. Pathophysiological mechanisms underlying these phenomena are not entirely known, but functional changes in afferent neuronal input to the spinal cord and secondary affection of higher brain stem and subcortical centers are probably involved.
