Kinematic and clinical changes over time. a DI: Distance index (%); b AC: Accuracy index (%); c VE: Velocity index (%); d SM: Smoothness index (%); e The four robot-based kinematics, all directions pooled, are represented; f FM: Fugl Meyer total score and sub-scores are represented. Coord velocity subscore, “Coordination velocity” (rapid alternating elbow movements). Results expressed as mean ± standard error of the mean. For the sake of figure clarity, asterisks indicating significance of changes since M2 have not been added in a, b, c, d, e, f; please refer to Tables 2 and 3 for statistical results
