Bimanual isometric force control: Asymmetry and coordination evidence post stroke

Highlights ► Stroke leads to increased asymmetry and reduced coordination between hands during a bimanual isometric force control task. ► Stroke survivors show more force control impairments with a smaller proportion of total force contributed by their impaired hand and a greater time-lag between ha...

Description
Summary:Highlights ► Stroke leads to increased asymmetry and reduced coordination between hands during a bimanual isometric force control task. ► Stroke survivors show more force control impairments with a smaller proportion of total force contributed by their impaired hand and a greater time-lag between hands during a bimanual task. ► Overall, the findings strongly suggest that movement benefits will accrue when rehabilitation protocols for the upper extremity train symmetry and coordination between hands.
