Remediation of the Non-Paretic Arm in Stroke

Stroke survivors with severe contralesional paresis often have substantial control and coordination deficits in the non-paretic arm. Because this arm must serve as the primary controller, these deficits can be functionally devastating. The investigators now hypothesize that the combination of severe paresis (Upper Extremity Fugl-Meyer Score ≤35) and persistent motor deficits in the non-paretic arm limits functional independence in chronic stroke survivors. The investigators predict that remediation, focused on the non-paretic arm should improve functional independence. The investigators propose a randomized study design with two tracts, two periods and four assessments. The investigators envision this study as the first step in establishing the basis for a rehabilitation approach that focuses on remediation of BOTH arms, which constitutes a substantial change from current remediation protocols focused only on the contralesional arm.
