Reaching in Stroke

"The visual feedback condition will use a monitor to display two cursors (empty circles) that will represent the participant's hands, and the circles will fill with red ink as the user starts to compensate outside a normal error band. The amount of red ink will increase proportionally to the magnitude of trunk compensation.~The goal of the participants will be to move their hands/cursors towards a target, while keeping the cursors as empty as possible."

"A monitor will display the same cursors as in the visual feedback condition, however, the cursors will be completely empty and will not fill with color.~The force feedback cues will be provided as resistance to move the robots' handles. These cues will be applied when the user moves outside a normal error band. In addition, the magnitude of the cue will be proportional to the magnitude of trunk compensation.~The goal of the participants will be to move their hands/cursors towards a target, while moving the robots with the least resistance possible."
