Abstract

The occurrence of abnormal involuntary movements as sequelae of epidemic encephalitis is well known. The most familiar of such movements are myoclonias, choreiform movements, disturbances of the respiratory cycle and oculogyric crises. Ornsteen1 observed a variety of less common hyperkinetic signs in a group of cases of chronic epidemic encephalitis with parkinsonism. All of these movements were involuntary and occurred abnormally in association with one or another automatic movement pattern. Included in the group were: elevation of one arm so that the hand rested on the chest while walking in one instance, and similar elevation of both arms until the hands were placed on the occiput in another; akinesia of one arm and hyperkinesia of the other in walking; elevation of the left forefinger while using the right hand in writing, and synchronous deviation of both extended arms to the left, followed by transitory pill-rolling movements of the fingers
