Abstract:

Hemispatial neglect frequently occurs after unilateral stroke. It is characterized by an inability to orient, perceive and interact with stimuli contralateral to the lesioned hemisphere. Despite its high prevalence and its negative impact on rehabilitation and quality of life, current neuropsychological tests for hemispatial neglect lack sensitivity, specificity, and test-retest reliability. In contrast to conventional paper-and-pencil tests, new technologies such as immersive Virtual Reality (iVR) allow for dynamic measures more closely resembling daily-life performance of patients and may thus offer new insights in this debilitating condition. In this study, we investigated the added value of iVR in the assessment of hemispatial neglect. To this end, we compared an assessment using iVR with conventional paper-and-pencil tests, computerized tests and clinical judgement on the presence of neglect. Our results confirmed that paper-and-pencil tests lack sensitivity in detecting subtle neglect-related deficits. The iVR assessment and a Posner computerized test corresponded equally well with clinical judgement. Furthermore, our results suggest that an ipsilesional deviation in head orientation assessed using iVR could be used as a marker of hemispatial neglect. Future research is needed to confirm the added value of new technologies such as iVR in the assessment of hemispatial neglect.
