Histograms, averaged across all subjects, depicting time the hand of the impaired limb spent in different regions of the workspace. a Reach Distance. Distance of the hand from the shoulder, represented as a fraction of arm length (0: hand coincident with shoulder; 1: arm fully extended). b Hand Elevation Distance. Vertical location of the hand with respect to the shoulder, represented as a fraction of arm length (0, hand elevation equal to shoulder elevation; 1: hand elevation full arm length below shoulder elevation; negative values indicate hand elevation above shoulder elevation).
