(A) Tremor severity. Group scores from Part A (resting, postural, action/intention) and Part B (Archimedes spiral/line drawing, water pouring) of the CRST for the hand treated in the first procedure (Hand one; MRgFUS₁) and the second procedure (Hand two, MRgFUS₂) plotted as least square means (CRST LS‐MEAN). Shaded areas CI‐95%. Baseline measures were collected <2 weeks prior to each MRgFUS procedure. Follow‐up measures were collected median 3.9 months after MRgFUS₁ and median 4.4 months after MRgFUS₂. Higher scores suggest worse tremor. (B) Equilibrium assessment for MRgFUS₂. Gait and stance items of the SARA plotted as least square means (SARA LS‐MEAN). Higher scores suggest worse equilibrium. Shaded areas CI‐95%. (C) Quality of life. QUEST domain scores were reported as a percentage of the highest possible total for that given domain. Higher scores suggest worse quality of life. Shaded areas CI‐95%.
