Motor exercises in the virtual environment. The two scenarios (VRRS® Khymeia Group, Ltd. Noventa Padovana. Italy) represent: A) a simple reaching movement: the patient has to raise the red glass and place it among the blue glasses on the shelf, according to a pre-recorded path (yellow line); B) a complex movement of increasing difficulty: the patient has to move the blue ball through the orange circles. The green box represents the start zone, while the yellow box represents the end zone to reach, following the circular-like displayed path.
