Clinical outcomes depend on precise electrode placement and optimal stimulation parameters.

VAS\u2010guided programming identifies patient\u2010specific sweet spots and delineates connectivity profiles associated with clinical benefit. Particularly, VAS\u2010derived sweet spots were more dorsal than previously suggested targets, highlighting the importance of incorporating subjective feedback to refine optimal stimulation regions.
