Abstract
Background Virtual technologies (VR) could respond to several challenges in Unilateral Spatial Neglect (USN) assessment, particularly the lack of sensitivity and ecological validity of traditional paper-and-pencil tests. A scoping review was conducted to explore current trends in this area. Methods PubMed, EMBASE, PsycINFO, Web of Science, IEEE, ACM, and the Cochrane Library were systematically searched for VR USN assessment. The Joanna Briggs Institute methodological guidelines for scoping reviews were used to inform our methodology. Results Thirty-one publications were included. There were two populations: healthy adults (n = 349) and post-stroke individuals (n = 903). A classification based on tasks and type of interaction used was proposed. Correlations with paper and pencil tests (PPTs) were often significant when the task structure was similar to PPTs but was lacking for activities with more dynamic components. The ecological validity of the tasks was assessed in comparison with the Catherine Bergego Scale (n = 4) and a real-world navigation task (n = 1). Using VR, USN disorders have been characterized using a wide range of indicators. Conclusions Few studies have addressed ecological validity, yet the use of VR in the assessment of the USN in this scoping review shows an undeniable contribution compared to traditional pencil-paper tests, especially for capturing the patient’s behavior toward the far extrapersonal space, essential in daily life.
