The occurrence of abnormal movements is a frequent reason for consultation in neurology. The etiologies are broadly separated into "primary causes", intrinsically neurological diseases (of genetic or degenerative origin), and "secondary causes". In addition to certain medications or toxic substances, brain damage can be a cause. In this register, 22% of involuntary abnormal movements are related to a stroke and 1 to 4% of strokes are complicated by abnormal movements. These are manifested by a parkinsonian syndrome or conversely by hypercinesia which can take the form of chorea or ballisms. Most hyperkinetic movements occur in the acute phase of the neurovascular event. The frequency of these abnormal movements is still uncertain and their semeiological description has been the subject of only rare publications. It seems relevant to be interested in the frequency of these neurological phenomena and has their semeiologic characteristic
