    Kinematic and kinetic variables that are significantly different between the paretic and nonparetic arm at 1 month poststroke. Values are group averages ± SDs. Abbreviations: Ap, peak acceleration; AR

    Kinematic and kinetic variables that are significantly different between the paretic and nonparetic arm at 1 month poststroke. Values are group averages ± SDs. Abbreviations: Ap, peak acceleration; AROM, active range of motion; MVCEX, isometric muscle strength of elbow extensors; MVCFL, isometric muscle strength of elbow flexors; SM, movement smoothness; Va, movement speed; Vp, peak velocity. All variables are significant for comparisons between the paretic and nonparetic arms (P<.001).
