  • Publication number: 20170361217
    Abstract: A system provides bi-manual game-based integrative therapy combining cognitive training with mild upper body physical exercising during game play. The system includes a pair of interfaces tracking a user's arms in 3D and detect trigger pressing. Custom therapeutic game controllers that detect grasping force, finger extension, 3D hand position, skin temperature and pulse may be used. Using one of these interfaces the patient plays a series of custom games displayed on a laptop, medical grade workstation, or other computer platform. The whole therapeutic system may be integrated on a medical cart, so to make the system mobile and easier to place in a clinical setting. Games were designed to improve motor control, shoulder strength, finger and arm range of motion, task sequencing, focusing, decision making (executive function), short term and long term visual/auditory memory, and were progressed in difficulty over 6 to 8 weeks of therapy. This therapy reduces depression.
