Fahn-Tolosa-Marin tremor rating scale scores over time following frameless radiosurgical thalamotomy.

Domain	Baseline	3 months	p-value	6 months	p-value	9 months	p-value	12 months	p-value
	N=29	N=26; N=25^*		N=20; N=19^*		N=17; N=16^*		N=12; N=11^*

Part A: Tremor Severity during rest, posture, action positions	12 (9–14)	9 (6–13)	0·121	7 (5–8)	0·001	10 (7–11)	0·017	7 (5–11)^*	0·083
Part B: Handwriting and Pouring	18 (13–25)	13 (7–17)^*	0·003	12 (7–15)	0·001	14 (10–18)	0·01	10 (5–18)	0·005
Part C: Functional Disability	15 (13–17)	10 (6–16)	0·004	7 (6–10)^*	0·001	7 (6–11)^*	0·005	7 (6–11)^*	0·006
Total	46 (38–55)	30 (21–45)^*	0·003	24 (19–31)	0·001	32 (26–40)	0·004	26 (14–39)	0·003

Scores are summarized by median (interquartile range). Statistically significant p-values, obtained by Wilcoxon Signed Rank test comparing each post-treatment timepoint to the pre-treatment baseline, are bolded.
