Programming for Stimulation-Induced Transient Nonmotor Psychiatric Symptoms after Bilateral Subthalamic Nucleus Deep Brain Stimulation for Parkinson’s Disease

Figure 3

Programming protocol flow diagram (After determining STPS causative active contacts with Figure 2, (A) record the initial parameters and programming according to the stimulation mode; (D) recover the initial parameters and reduce voltage 0.3 V–0.5 V and increase pulse width by 10–20 s; (E) if STPS relapsed, then reduce voltage 0.1–0.3 V and reduce frequency 10–30 Hz, increase pulse width 10–20 s, and keep the total electrical energy delivered (TEED) equal to the counterpart of (D), TEED = voltage²  × frequency × pulse width/impedance; (F) decrease frequency to 125 Hz and decrease voltage 0.3–0.5 V, and keep the TEED equal or slightly higher to the counterpart of (D) or (E); activate the other dorsal contact with interleaving mode.).
