Mental Practice in Chronic, Stroke Induced Hemiparesis

Stroke is the leading cause of disability in the United States, producing motor impairments that compromise performance of valued activities. Hemiparesis (or weakness in one arm) is particularly disabling, is the primary impairment underlying stroke-related disability, and the most frequent impairment treated by therapists in the United States. This study will test efficacy of a promising technique in reducing arm disability and increasing function, thereby improving outcomes and health, reducing care costs, for community dwelling patients with stroke-induced hemiparesis.
