Fig. 4From: Effects of robot therapy on upper body kinematics and arm function in persons post stroke: a pilot randomized controlled trialRobot-based indexes computed from the reaching trajectories executed during the 20 sessions of robot therapy. Point: mean; whisker: 95% confidence interval. a Maximum force generated by the robot. Positive and negative values indicate, respectively, assistive and resistive force. b Mean duration of reaching movements. c Number of movement units. Lower values indicate smoother movementsBack to article page
