Behavioral indicators of the cursor trajectories during the motion tasks (motion trajectories) in absence of external force (FS), in presence of assistive (AF) or resistive (RF) force and during the isometric task (IF, force profiles). Control subjects (C) and MS subjects (MS) are shown with different colors as indicated in the legend. Darker and brighter colors represent the dominant (D) and non-dominant (ND) arm respectively. The error bars indicate the standard error of the indicators. * indicates significant differences (p < 0.05) between subject groups (C vs MS) for each task.
