(A) GPi on the left side: during the monitoring process, GPi discharge was recorded from 6.50 mm above the target to 0.50 mm above the target, and the electrode was placed at 0.50 mm above the target. (B) GPi on the right side: during the monitoring process, GPi discharge was recorded from 6.20 mm above the target to 0.30 mm above the target; and the electrode was placed 0.50 mm above the target.

The accuracy of the electrode placement was confirmed through a fusion of preoperative and postoperative brain magnetic resonance imaging and computed tomography data, respectively (Figures 1, 2).
(A) Preoperative craniocerebral 3.0 T MRI and skull CT data with frame were imported into Surgiplan software to develop the surgical plan. (B) CT scan after operation showed no bleeding or bubble around the electrodes. (C) Postoperative CT and preoperative MRI fusion showed that electrode implantation trajectory and implantation position were accurate.

(A) Trends in HAMA scores. (B) Trends in HAMD scores. (C) Trends in BFMDRS-Movement scores. (D) Trends in BFMDRS-Disability scores. (E) Trends in FTM-TRS scores. (F) Trends in SF-36 scores. (G,H) Drawing A, B, C of FTM-TRS was tested before surgery and 6 months after surgery using the dominant and severely symptomatic right hand. HAMA, Hamilton Anxiety Scale; HAMD, Hamilton Depression Rating Scale; BFMDRS, Burke-Fahn-Marsden Dystonia Rating Scale; FTM-TRS, Fahn-Tolosa-Marin Tremor Rating Scale; SF-36, 36-item Short Form Health Survey.
