Experimental group: Will receive the game-based rehabilitation program delivered at home. The program for gaze will include provision of the motion mouse (Gyration). This approach provides a highly flexible treatment tool applied to train gaze control, and allows incorporation of graded balance demands. The use of this HID compliant computer input device allows many different therapeutic exercises to be coupled to a wide range of inexpensive commercial computer games. Though initially designed for clinical use, with the easy to use and inexpensive motion sense mouse and computer games this intervention approach can be extended to home settings. Many therapeutic exercises and activities (singly or in combination) can be used to practice a variety of gaze and balance skills, and, importantly, while playing fun computer games.
