Divided attention and manual visuomotor control in stroke: a combined dual-task and eye movement study.

ABSTRACT:

Background

Daily manual tasks require cognitive-motor interactions. There is limited research on cognitive-motor dual-tasks involving the upper extremity. In this study we used a manual visuomotor dual-task to measure post-stroke cognitive-motor impairments. Given previous evidence of impaired cognitive-motor interaction in stroke we hypothesized that the presence of enhanced dual-task cognitive load will impact motor performance in stroke patients. We also hypothesized that this dual-task effect would be greater in stroke patients compared to healthy controls. We also explored whether cognitive-motor impairments observed in these single- and dual-task conditions would relate to deficits in manual dexterity.

Methods

30 chronic stroke participants (29.77 ± 35.39 months post-s
