    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.
