Note. ARAT = Action Research Arm Test; D = dominant; F = female; M = male; ND = nondominant; OP = outpatient; UE = upper extremity.

^aScored on a scale ranging from 0 to 57 points, where higher scores indicate better UE function (clinically important change = 5.7 points).

^bValues are the median of each participant’s second-by-second values. Normative value are as follows: mean = 135, standard deviation = 36, where higher values equal greater intensity of movement.

^cValues are the median of each participant’s second-by-second values. Normative values are as follows: mean = −0.1, standard deviation = 0.16, where 0 indicates equal contribution from each UE to an activity.

^dNormative values are as follows: mean = 0.95, standard deviation = 0.06, where 1 indicates equal duration of activity for both UEs.
