Application of VR-technologies for neurorehabilitation of patients with motor and cognitive function disorders

The article explores the use of developed interactive 3D application with VR technology support, designed for the rehabilitation of patients after neurological disorders that cause motor and cognitive impairments. The neurorehabilitation hardware and software system is implemented on the Unity platform and includes an interactive 3D application and a Quest 3 VR headset. The VR headset consists of a virtual reality helmet and two controllers for the right and left hands, respectively, and supports highly accurate controller tracking using built-in cameras equipped with LiDAR technology. The causes of unilateral spatial neglect syndrome, or hemispatial neglect, and the possibility of its rehabilitation are considered. The hardware and software system developed by the authors enhances patient motivation through gamification and adaptive scenarios, allowing them to select and visualize various 3D scenes. When immersed in a realistic virtual environment, the patient acts instinctively. This helps develop hand motor skills, a sense of balance and spatial navigation abilities. Furthermore, the hardware and software system allows for the convenient storage of statistical data on the progress of prescribed procedures and can be used for further analysis during rehabilitation process.
