Note: UE: upper extremity; M: male; F: female; SMC: sensorimotor cortex (BA 4, 6, and/or 3, 1, 2); IC: internal capsule; BG: basal ganglia; PC: parietal cortex (BA 7 and/or 39, 40); DLPF: dorsolateral prefrontal cortex (BA 8, 9 and/or 46); IF: inferior frontal cortex (BA 44); TC: superior and middle temporal gyrus (BA 22, 21, and/or 37).
Years poststroke are calculated as time elapsed between incidence of stroke and day of data collection.
Lesion volume is computed from MRI or CT.
Language ability was assessed using the Sequential Command Subtest from the Western Aphasia Battery.
Maximum score on the UE motor subscore of the Fugl-Meyer Motor Assessment is 66.
Grip strength from dynamometer are expressed as standardized T scores.
