P174. Effects of left and right brain damage on anticipatory motor behavior during grasping and lifting with the ipsilesional hand

Behavioral studies in patients with left and right brain damage revealed the specialized function of both hemispheres in motor control. Recently, we investigated anticipatory grip force control in patients with stroke affecting the left or the right hemisphere during object lifting with the ipsilesional non-paretic hand. We found imprecise anticipation of grip force to the weight of everyday objects (like a carton with milk or a package of paper tissues) in patients with left brain damage while patients with right brain damage performed closer to normal.
