Abstract
[Abstract] After stroke, the ability to perform two tasks concurrently is diminished,
which may contribute to less pronounced gains on activity level after rehabilitation.
The current study investigated whether upper extremity dual-task performance is
compromised after stroke, as a first step towards examining whether cortical
stimulation can reduce dual-task interference. Twenty stroke patients performed a
single motor task (tapping targets), single cognitive task (memorising digits) and
dual motor-cognitive task. Although motor performance was better when per-
forming the dual-task compared to the single tapping task, it was at the expense of
cognitive performance. These findings suggest upper extremity cognitive-motor
interference after stroke. In ongoing work, we are investigating the potential role of
cortical stimulation to improve motor and cognitive dual-task performance.
