Involuntary Movement Associated with Stroke

Involuntary movement is a rare symptom associated with cerebrovascular disease. Ballism, chorea, athetosis, dystonia and tremor are differrent types of involuntary movements. However, the differences among involuntary movements seem to be phenomenological. These abnormal movements may be combined or changed into other involuntary movements. Lesions identified by CT or MRI give some clues as to the pathophysiology of involuntary movements caused by stroke. These movements have occasionally been reported during acute phase of stroke as well as after months or years of delays. However, the pathophysiological mechanisms of involuntary movements are poorly understood. More case reports and studies are required to fully understand the mechanism. We analyzed the patients with involuntary movement after stroke and propose a pathogenic mechanism and clinical course for this disorder. 뇌졸중과 연관된 불수의 운동
