Key result
Immersive VR links post-stroke visuospatial neglect to significantly longer and more extended visual searches.
Why the study?
Does immersive virtual reality characterize visual search behaviour differences in individuals with visuospatial neglect after stroke compared to controls?

Does immersive virtual reality characterize visual search behaviour differences in individuals with visuospatial neglect after stroke compared to controls?
Immersive VR tasks can detect subtle visual search inefficiencies in stroke patients that conventional assessments may overlook.
= 11). Additionally, we examined how task parameters (target position, spatial context, and difficulty) influenced search behaviour. Results show that VSN+ exhibited least efficient search strategies, with longer search times than VSN- and HC and more extended search paths than HC. Notably, VSN- also demonstrated visual search inefficiencies, suggesting that conventional assessments may overlook subtle visuospatial impairments. Search deficits were most pronounced in extra-personal space and under increased task demands. Despite a limited sample size, these findings highlight the potential of VR-tasks to characterize visual search behaviour. Further research on larger, more diverse samples is needed to evaluate its potential diagnostic utility.

Embrechts et al. (2025) conducted an observational in Visuospatial neglect after stroke. Immersive virtual reality tasks vs. Healthy controls and stroke patients without visuospatial neglect was evaluated on Visual search behaviour (search times and search paths). Immersive virtual reality tasks revealed that stroke patients with visuospatial neglect exhibited longer search times and more extended search paths compared to those without neglect and healthy controls.
