The objective of this project is to develop a conceptual framework, design, produce and preliminary evaluate a HeadRehab's prototype virtual reality (VR) application in order: a) to proper assess functional impairments due to traumatic brain injury (TBI), via identification of changes in the brain functions, as a first step of patients' rehabilitation protocol; and b) to facilitate re-acquisition of fundamental cognitive and behavioral neural substrates temporary disabled due to TBI. First, we will link TBI symptoms to their underlying mechanisms and will produce VR application (computer graphics modules) to examine how cognitive (i.e., memory, attention and spatial awareness) and behavioral (i.e., visual-kinesthetic sense involved in postural control) neural substrates are interactively affected by the TBI. Second, within the concept of "neuroplasticity" we will ultimately develop a fully immersive VR prototype incorporated with "VR-driven feedback" and suitable interface between TBI patients and computer generated 3-D "enriched environment. Third, an executive task controller will be elaborated allowing a) the rehabilitation therapist to constantly challenge the patients and maintain his or her optimal level of effort and b) the TBI patient to effectively interact with precisely controlled VR environment contingent upon his/her intact physical capabilities. Fully developed HeadRehab's VR prototype may be applied for solders, athletes and ordinary civilians suffering from a wide range of TBI (from mild to severe), and will be most beneficial for patients experiencing long-lasting cognitive-motor and balance residual disabilities.
