‘Toap Run’ exergaming. A ‘Toap run’ exergame. Active training involves full-body movements, performed in front of an RGB-D Kinect^® motion sensor positioned approximately 2 m away from the patient. These movements encompass large-amplitude rapid movements of all four limbs, pelvis, and trunk, incorporating lateral, vertical, and forward displacements, which are schematically represented for each environment. As the patient moves, a small animal (the avatar) is simultaneously displaced in real time within three different environments: the garden (left), the mine (middle) and the river (right). The objective is for the avatar to collect coins while avoiding obstacles. In contrast, the control training patients underwent seated training, interacting by pushing buttons on the keyboard
