Computed Three-Dimensional Atlas of Subthalamic Nucleus and Its Adjacent Structures for Deep Brain Stimulation in Parkinson's Disease

Figure 8

Relationships between the localization of the most effectively stimulated contact and the UPDRS motor score of items 27, 28, 29, and 30 as gait disturbance. The best improvement of gait disturbance was achieved in 9 cases of all 11 cases by bilateral deep brain stimulation of each paired combination among the subthalamic nucleus, zona incerta, and field of Forel H and in one case by unilateral stimulation of the zona incerta. Pre: before surgery, post: after surgery. STN: subthalamic nucleus, ZI: zona incerta, FH: field of Forel H, and number: case number.
