    AbstractRarely, the postoperative management of patients with subthalamic deep brain stimulation (STN-DBS) is complicated by pharmacologically intractable dyskinesias. Here we report that in three of these patients additional stimulation of a proximal contact located within the subthalamic white matter may lead to a significant reduction of dyskinesias associated with STN-DBS. We propose that pallidofugal fiber tracts play a major role in the etiopathology of dyskinesias and their blockade through DBS may explain our observations.
