^aPrimary tasks (1°) are listed in the left column (SB = shoulder abduction, SD = shoulder adduction, EF = elbow flexion, EE = elbow extension, WF = wrist flexion, WE = wrist extension, FF = finger flexion, FE = finger extension). Each primary task has 3 secondary joint torques associated with it, which are listed in the second column (S = shoulder, E = elbow, W = wrist, F = fingers). Data were tested for differences between groups using a mixed model ANOVA, or a Kruskal-Wallis nonparametric test (indicated by an asterisk), depending on the normality of the data tested. Post hoc comparisons among the paretic arms of the CH group and combined arms of the TD group are shown, and are also nonparametric if the Kruskal-Wallis nonparametric test was used. All comparisons that reached a significant level of P < .05 are highlighted in gray.
