All p values from paired t-tests calculated between pre-surgical and post-surgical except †paired t-test vs. pre-surgical off med; ‡Wilcoxon signed-rank test. aN = 20. bN = 19. Note: off stim and on stim refer to the post-surgical visit only; e.g., on med / on stim refers to on medication at the pre-surgical visit and on medications and on stimulation at the post-surgical visit.
