Differences in endpoint error depending on visual feedback condition. (a) Mean endpoint error for trials with hand feedback (vision) compared to trials with no hand feedback (no vision). Performance by control subjects is shown by the grey dots. Stroke performance of the affected arm is shown by the leftward and rightward pointing triangles representing left-affected and right-affected subjects respectively. Dotted line shows 95th percentile of control performance and solid vertical line shows target radius. (b) Mean endpoint error for trials with hand feedback (vision) compared to mean return time for the affected arm. (c) Mean endpoint error for trials with hand feedback (vision) compared to strength scores in the clinically defined affected arm. (d) Same as (c) but for ‘unaffected’ arm.
