Study Arms:
- Omnidirectional followed by directional DBS (Type: None): Omnidirectional DBS is used for the first 3 months in all subjects, unless not tolerated. Directional DBS is used for months 3-6 in all subjects with a directional DBS lead. Primary end point is based on double-blind testing of omnidirectional vs. directional DBS in randomized order at 3-month follow-up visit.~In this Observational study design, all interventions here are therapeutic interventions that are part of the standard of care, rather than assigned as part of an interventional study.

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