Stroke’s hemispheric localization affects motor performance: a lesion of the right hemisphere affected performance, re-ducing average speed and smoothness and augmenting lateral deviation in both arms. Instead, a lesion of the left hemi-sphere affected the aiming error, impairing the feedforward control of the ipsilesional arm. Behavioral indicators: aver-age speed (A), smoothness index (B), lateral deviation (C) and 100-ms aiming error (D) computed from the cursor tra-jectories. Controls (C, grey bars) and subjects with Right Brain Damage (RBD, green bars) and Left Brain Damage (LBD, red bars) moved in presence of assistive (AF), resistive (RF) and in absence of external force (NF). The movements were performed with the right (bars with uniform color) and left (bars with diagonal lines) arm. Error bars indicate the stand-ard error of the indicators. The contralesional arm (paretic) corresponds to the left (L) arm in RBD subjects and to the right (R) arm in LBD subjects. The ipsilesional arm (non-paretic) corresponds to the right (R) arm in RBD subjects and the left (L) arm in LBD subjects. * indicates significant differences (p < 0.05).
