In the present \nstudy, we investigated 10 patients with right cerebral \nlesions and 25 healthy controls using a task to uncouple \ndeficits in sensory perceptual systems and motor-action \noutput systems on directional hypometria. This task required \nparticipants, with their eyes closed, to reproduce lateral \nand medial horizontal displacements (15\u201327 cm) with \neach arm. Each participant was seated at a waist high table \nand had their hand placed at an origin point aligned with \nthe axillary fold on the same side. Their hand was moved \nby the investigator from the origin point to a target point \nand brought back to the point of origin (input displacement). \nThe participant was then asked to return their hand to \neither the same target point or to an equidistant target \npoint in the opposite direction. Healthy dextral participants \nwere significantly more hypometric with their right arm, \nbut patients with right cerebral lesions exhibited an opposite \npattern with overall left arm hypometria. In addition, \npatients were significantly more hypometric for movements \nwhen output displacements were toward left hemispace. No \neffect was found for direction of sensory input. The results \nsuggest that the directional hypometria is predominantly \nproduced by hemispatial output deficits.
