Objective – To investigate the potential of our newly developed three‐dimensional immersive virtual reality (VR) program modeled on a real street crossing as an assessment tool for extrapersonal neglect in stroke patients. Methods – Thirty‐two patients with right‐hemispheric stroke (neglect group, 16; non‐neglect group, 16) were enrolled. The deviation angle, reaction time, left‐to‐right reaction time ratio, visual and auditory cue rates, and failure rate were evaluated during missions to keep a virtual avatar safe from a traffic accident in the VR program. The line bisection test and letter cancellation test were also evaluated. Results – The deviation angle, left‐to‐right reaction time ratio, left visual and auditory cue rates and left failure rate in the VR program showed significant differences between the two groups ( P < 0.05). Depending on the direction of approach of the virtual car, the left parameters were significantly higher than the right parameters in the neglect group ( P < 0.05). In the neglect group, the line bisection test correlated significantly with the deviation angle ( P < 0.05). None of the other virtual reality parameters significantly correlated with the paper and pencil tests. Conclusion – Post‐stroke neglect in the extrapersonal space can be easily and safely detected and measured using our three‐dimensional immersive virtual street crossing program.
