Hand Function and Motor Cortical Output Poststroke: Are They Related? Brenda J. Brouwer, PhD, Kim Schryburt-Brown, MSc Archives of Physical Medicine and Rehabilitation Volume 87, Issue 5, Pages 627-634 (May 2006) DOI: 10.1016/j.apmr.2006.02.006 Copyright © 2006 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation Terms and Conditions

Fig 1 Representative electromyograms from (A) a control subject, (B) a subject with chronic stroke, and (C) a subject with subacute stroke showing side-to-side differences in silent-period duration (vertical dashed lines) and active MEP amplitudes. Note different scaling. Abbreviations: L, left; NP, nonparetic; P, paretic; R, right.

Fig 2 Scatterplots showing the relations between tapping ability and neurophysiologic measures of (A) motor threshold, (B) MEP amplitude, (C) MEP latency, and (D) silent period duration. The linear regression line and 95% confidence bands based on all data are shown.
