Correlation between the laterality index (LI) and (a) Fugl-Meyer score, (b) relative strength (percentage of maximum paretic adduction torque relative to the maximum non-paretic adduction torque), and (c) secondary elbow torque (torque generated in the paretic limb during isometric shoulder abduction; normalized to the subject’s maximal elbow flexion or extension torque depending on the direction of the secondary torque; Flex flexion, Ext extension). * Indicates the correlation is significant at the P < 0.05 level
