Development of a Visual Cueing System Using Immersive Virtual Reality for Object-Centered Neglect in Stroke Patients

Unilateral spatial neglect (USN) is defined as failure to report, respond, or adjust to novel or meaningful stimuli presented to the side opposite a brain lesion. This symptom deteriorates the rehabilitation efficiency and hinders activities of daily living. USN is classified into 2 sub-categories: body-centered neglect and object-centered neglect. No optimal intervention has been proposed for treating object-centered neglect. Thus, we developed a visual cueing system using immersive virtual reality to improve object-centered neglect. A feasibility study showed 2 typical measurements for object-centered neglect tended to improve the symptom, these results provide preliminary evidence for designing successful rehabilitation programs using a visual cueing system in patients with object-centered neglect.
