BACKGROUND Weakness is often profound in the contralesional hand after stroke. Relative contributions of various neural and mechanical mechanisms to this impairment, however, have not been quantified. In this study, the extent of one potential contributor, muscle atrophy, was noninvasively assessed in index finger musculature using ultrasonographic techniques. METHODS Twenty-five stroke survivors (45-65 years old) with severe hand impairment resulting from a stroke occurring 2-4 years prior… CONTINUE READING
