1 Time-Course of Changes in Arm Impairment After Stroke: Variables Predicting Motor Recovery Over 12 Months  Mehdi M. Mirbagheri, PhD, W. Zev Rymer, MD, PhD  Archives of Physical Medicine and Rehabilitation  Volume 89, Issue 8, Pages (August 2008) DOI: /j.apmr Copyright © 2008 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation Terms and Conditions

2 Fig 1 A typical movement trajectory of rapid elbow extension generated by a typical nonparetic and paretic arm at 1 month poststroke for (A) position, (B) velocity, and (C) acceleration. Abbreviations: Ap, peak acceleration; AROM, active range of motion; Vp, peak velocity.

3 Fig 2 Recovery patterns of motor impairment assessed by the FMA. (A) The predicted means are the solid lines; the observed means are the dashed lines. (B) The mean trends are the solid lines. The boundaries (±1 SD) are the dashed lines. Red, class 1; blue, class 2.

4 Fig 3 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).
