Changes in objective assessment for kinematic analysis before and after 2-week intervention for all six patients. Conditions for the task movement were that 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. a Movement time for the wrist, b trajectory length for the wrist, c trajectory length for the shoulder, and d forward displacement for the shoulder. P1 to P6 correspond to patients 1 to 6 in the tables, respectively
