Abstract

Objective: Unilateral spatial neglect (USN) assessment is commonly based on paper-and-pencil tests, including the line bisection task. However, this task lacks sensitivity and does not reflect the symptomatic heterogeneity of USN patients, such as difficulties in extrapersonal space or encountered in daily life. Immersive virtual reality (VR) could be a promising way to improve the line bisection task by developing versions that better reflect the difficulties experienced by patients. This study investigated the feasibility and the psychometric qualities of different immersive VR bisection tasks.

Method: 22 right-brain damaged patients with confirmed left USN (USN++) on conventional USN assessment tools, signs of left USN (USN+), or without USN (USN-), and 39 healthy participants were recruited and performed three different immersive VR bisection tasks-a proximal and a distal line bisection task and an ecological baguette bisection task.

Results: Correlational analyses with conventional USN assessment tools supported the validity of the immersive VR bisection tasks. Group and individual analyses emphasized the better sensitivity of the immersive VR proximal and ecological tasks compared with the paper-and-pencil line bisection task. The immersive VR proximal bisection task showed high sensitivity to detecting USN++ patients (detection rate: 75.0%) but not USN+ patients, while the immersive VR ecological bisection task showed good sensitivity for detecting both (detection rate: 62.5%), supporting its relevance for diagnosing mild USN.

Conclusions: The immersive VR bisection tasks appear relevant for USN diagnosis, especially the ecological one, which supports the need for more ecological assessment tools to assess USN and plan rehabilitation better. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

验证沉浸式虚拟现实线和法棍等分任务对单侧空间忽视的评估。

目的：单侧空间忽视（USN）的评估通常基于纸笔测试，包括线平分任务。然而，这项任务缺乏敏感性，不能反映USN患者的症状异质性，例如在超个人空间或日常生活中遇到的困难。沉浸式虚拟现实（VR）可以通过开发更好地反映患者所经历的困难的版本来改善线平分任务，这是一种很有前途的方法。本研究探讨了不同沉浸式VR对分任务的可行性和心理测量学性质。方法：招募22例经常规USN评估工具确认为左USN （usn++）、左USN （USN+）或无USN （USN-）的右脑损伤患者和39名健康参与者，并进行三种不同的沉浸式VR平分任务-近端和远端线平分任务和生态法棍面包平分任务。结果：与传统USN评估工具的相关分析支持沉浸式VR平分任务的有效性。小组和个人分析强调，与纸笔平分线任务相比，沉浸式VR近端和生态任务的灵敏度更高。沉浸式VR近端平分任务对USN++患者的检测灵敏度较高（检出率为75.0%），对USN+患者的检测灵敏度较低，而沉浸式VR生态平分任务对USN+和USN+患者的检测灵敏度均较高（检出率为62.5%），支持其与轻度USN诊断的相关性。结论：沉浸式VR切分任务与USN诊断相关，特别是生态诊断，支持需要更多的生态评估工具来评估USN并更好地规划康复。（PsycInfo Database Record (c) 2025 APA，版权所有）。
