Pre and post-operative exam. Pre-operative assessment of tremor followed by post-operative tremor assessment during initial programming, complicated by hypomania and dyskinesia. Medtronic Activa PC Right STN settings: 1–, case+; 2.5 volts, 60 microseconds, 180 Hz. Left STN settings: 9–c+, 2.5 volts, 60 microseconds, 180 Hz. Lower stimulation voltages and frequencies were associated with poor tremor response. More dorsal active contact configurations were associated with reduced psychiatric adverse effects, though tremor benefit remained inadequate.
