FIGURE 1. Plots of clinical scores (mean ± SD) for motor UPDRS, H&Y, and S&E for preoperative (before DBS) and postoperative conditions with STN stimulators on (DBS on) and off (DBS off) and plots of daily consumption of levodopa (L-Dopa) therapy before and after DBS implantation. Clinical scores were assessed in unmedicated patients. Reduction in motor UPDRS and H&Y scores and increase in S&E score indicate improvement in motor function, global stage disease, and performance of activities of daily living, respectively. Differences between mean scores for UPDRS, H&Y, S&E were significant (P < 0.001). Differences between mean scores of daily consumption of levodopa therapy were significant (P < 0.05). Results are expressed as mean ± SD
