One vs. Two Handed Use After Stroke: Role of Task Requirements

This study proposes to explore in
people after stroke: i.) how specific functional tasks requirements relate to 1 vs. 2 handed use,
and ii.) how stroke severity impacts this arm use. We are proposing to study 15 individuals more
than 6 months after stroke in the CSU Motor Behavior Lab for a single 2-3 hour session of taskrelated
reaching. We will systematically vary task requirements (i.e. object size or weight,
location in workspace), and record use of 1 versus 2 hands using videotaping as well as
recording of quality of arm movement (kinematics) and muscle activity (EMG).
