Development of the 3D Evaluation System for Unilateral Spatial Neglect Using Immersive Virtual Reality

-An Explorative Study to Detect the Area of Neglect in Near and Far Space-

Abstract

USN is one of the sequelae of stroke, and it is the failure to response or report to meaningful stimuli which are presented on the opposite side to a cerebral hemisphere lesion. These symptoms can exist for near and far spaces combined or independently, and it is important to provide evaluation system for near and far space neglect. Therefore, we developed the system which enable evaluate both near and far space neglect with immersive virtual reality (iVR), and we performed a validation study in USN patients. As a result, we realized to describe the aspect of USN in both near and far space. In this report, the applicability of an evaluation system using iVR is shown; however, the reliability and validity must be confirmed for groups, and proof of clinical usefulness must be established.
