目的 观察发作性运动诱发性运动障碍 (PKMD)的临床特征及与癫的关系。方法 详细观察 4 1例PKMD的临床特征 ,影像学和脑电图改变。结果 4 1例均由运动诱发 ,呈发作性运动诱发性舞蹈手足徐动症 30例 ,发作性运动诱发性肌张力障碍 11例 ,发作时意识清楚 ,影像学有异常者 6例 ,脑电图有样放电者 12例 ,其中 2例发作时有样放电 ,脑体感诱发电位半数以上病例有定位侧半球改变。对抗药有良效。结论 本症障碍的部位可能在感觉刺激的传入通路与发作症状的传出通路之间的反射中枢。具有某些癫性质 ,推测与癫发作可能有某些共同的生物学基础
Objective To observe the clinical features of paroxysmal motor-induced dyskinesia (PKMD) and its relationship with epilepsy. Methods The clinical features, imaging and EEG changes of 41 patients with PKMD were observed in detail. Results All 41 cases were induced by exercise, 30 cases were induced by exercise-induced choreoathetosis, 11 cases were induced by exercise-induced dystonia. Their consciousness was clear at the time of attack, 6 cases with abnormal imaging, There were 12 cases of discharge, including two cases of attack when the discharge, brain somatosensory evoked potential more than half of the cases have the localization of the hemisphere change. Anti-tuberculosis has good effect. Conclusions The site of this disorder may be the reflection center between the sensory stimulating afferent pathway and the efferent pathway of the seizure symptoms. With some epileptic properties, it is speculated that there may be some common biological basis with epileptic seizures
