MAS, Modified Ashworth Scale (range 0–4, 4 indicating maximum spasticity). Only elbow portion of the scores for flexor and extensor muscles of the affected hand are reported here.

FMA, Fugl-Meyer Arm score (range 0–66, higher scores representing better arm function).

MMSE, Mini Mental State Exam (range 0–30, higher scores representing normal cognition).

NIHSS, NIH Stroke Scale (range 0–42, higher score imply severe motor impairments).

GS, Grip strength for affected hand reported as percentage of the unaffected hand score.

n/a, Data not available, since subject declined the MRI scan because of claustrophobia.
