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.
中枢神经系统创伤诱发的运动障碍已广为人知。然而，在过去几年中，外周诱发的运动障碍的作用已引起关注。我们描述了三名患者，他们分别表现出肌张力障碍、震颤以及伴有先前遭受创伤部位的身体震颤和肌张力障碍的舞蹈手足徐动症。这些现象背后的病理生理机制尚不完全清楚，但可能涉及脊髓传入神经元输入的功能变化以及更高位脑干和皮质下中枢的继发性病变。
