Objective: To examine whether reduced body-specific attention to paretic limb is found in chronic stroke patients in the time-dependent manner. Methods: Twenty-one patients with chronic hemiparesis (10 left and 11 right hemiparesis) after subcortical stroke and 18 age-matched healthy controls were recruited in this study. Standard neuropsychological examinations showed no clear evidence of spatial neglect in all patients. In order to quantitatively measure the spatial attention to paretic hand, a visual detection task for detecting a target appearing on the surface of either a paretic or dummy hand was used. This task can measure the body facilitation effect, which makes faster detection of a target on the body compared with one far from the body. Results: In stroke patients, there was no difference in the reaction time for visual target between on the paretic and the dummy hands, while the healthy participants showed faster detection for the visual target on the real hand than that on dummy one. The Index of the body facilitation effect, subtracting the reaction time for the target-on-paretic hand from that for the target-on-dummy one, was correlated with the duration since onset and with finger function test on the Stroke Impairment Assessment Set. Conclusions: The reduction of the body facilitation effect in paretic limb suggests the decline of body-specific attention to the paretic one in patients with chronic hemiparesis. This decline of the body-specific attention, leading to neglect for paretic limb, will be one of the most serious problems for rehabilitation based on use-dependent plasticity.
