Disease Duration Differentiates Freezing of Gait Response to Subthalamic and Nigral Stimulation for Parkinson's Disease in an Exploratory Multicenter Controlled Trial
Abstract Background Freezing of gait (FoG) belongs to most pressing unmet symptoms in the treatment of Parkinson's disease. Objectives To explore whether combined subthalamic and nigral (STN + SNr) deep brain stimulation improves FoG compared with optimized STN stimulation alone; to identify clinical variables associat...
