Fig. 2. The mean improvement of dyskinesia was reduced by 73.57% (from 3.44 preoperatively to 0.83 postoperatively) in patients with stimulation of the area above the STN, whereas the mean improvement of dyskinesia was reduced by only 37.44% (from 5.40 preoperatively to 3.07 postoperatively) in patients where the STN was directly stimulated. There was a significant difference between stimulation of the area above the STN and within the STN. STN, subthalamic nucleus.
