Reaching exercise for chronic paretic upper extremity after stroke using a novel rehabilitation robot with arm-weight support and concomitant electrical stimulation and vibration: before-and-after feasibility trial

Conditions for the task movement were that the individual patient (Pt.) could reach the maximum distance both before and after the 2 weeks intervention; Pt. 1 to 4 reached the target 30 cm away from the start in the sagittal and vertical directions, and patients 5 and 6 reached the target 20 cm away in the same directions. +, increase; −, decrease; these simply mean the changes of values, not significant changes in the mean. In the column “Change of movement pattern” only, “+” means that the movement pattern of the wrist had changed. “Unclear” was only assessed by the shapes of the trajectories
