Outcomes of globus pallidus internus deep brain stimulation in patients with pantothenate kinase-associated neurodegeneration (PKAN) assessed by the Burke–Fahn–Marsden Dystonia Rating Scale (BFMDRS). (A) Absolute changes in BFMDRS-M scores at 6–12, 24–36, and 60–72 months postoperatively compared to baseline. Means ± standard deviation (SD) are shown in the (A) bar chart. (B) Serial relative changes in BFMDRS-M scores, BFMDRS-D scores, and (C) subscores of BFMDRS-M compared to baseline in the 4 patients evaluated at all three time points. (D-I) Individual evolutions in absolute (D, G) and relative (E, H) BFMDRS-M and BFMDRS-D scores and colored per PKAN type (F, I). -M, movement subscale; -D, disability subscale; PreOP, preoperative.
