Study Arms:
- Dystonia Severity Assessment (Type: EXPERIMENTAL): We will measure the effects of DBS on dystonia by assessing changes in the Burke-Fahn-Marsden Dystonia Rating Scale at 2, 4, 6, and 12 months after surgery to implant the Boston Scientific Vercise PC IPG with directional DBS lead versus preoperative baseline.

Based on this trial design, predict the completion outcome and termination type (if applicable).
