Subject demographics for validity and reliability assessments.

Subject type	N	Gender (M:F)	Age (years)	FMA score	mRS score	Time since stroke (years)
A. TAXONOMY VALIDATION AND APPLICATION
Stroke	9	4:5	50.3 (42.6–70.2)	49.6 (26–61)	2.4 (2–4)	11.4 (0.5–38.4)
B. MACHINE LEARNING VALIDATION
Healthy control	5	2:3	28.1 (19.0–43.3)	N/P	N/P	N/A
C. TAXONOMY RELIABILITY ASSESSMENT
Stroke	7	3:4	51.4 (42.6–70.2)	47.1 (26–61)	2.5 (2–4)	7.7 (0.5–11.7)

All subjects were right-handed (premorbidly for stroke patients), as determined by the Edinburgh Handedness Inventory. All stroke patients were right-side paretic. Age, FMA score, and time since stroke are average with range in parentheses. The FMA measures UE motor impairment, with maximum score of 66 indicating fully normal movement. The mRS measures disability, with a score of 0 indicating no symptoms and 6 indicating death. Labeled data from seven of the nine stroke subjects in (A) were used for (C). FMA, Fugl-Meyer Assessment; mRS, modified Rankin Scale; N/P, not performed; N/A, not applicable.
