Abstract
We examined effects of a visual search task (VST) in virtual reality (VR) with a moving background on spatial cognition and standing balance in left hemiparetic strokes. The VST with background deviation was allocated to Case A. In Case B, the VST without the deviation was performed. As a results, in Case A, the reaction time of VST was shortened in the paretic space and ability of weight-shift to the paretic side was improved. In conclusion, the VST in the VR with a spatial manipulation may improve spatial cognition and standing balance in left hemiparetic strokes.
我们研究了虚拟现实（VR）中带有移动背景的视觉搜索任务（VST）对左侧偏瘫脑卒中患者空间认知和站立平衡的影响。在病例 A 中进行了有背景偏差的视觉搜索任务，在病例 B 中进行了无背景偏差的视觉搜索任务。结果发现，在病例 A 中，VST 在瘫痪空间的反应时间缩短了，向瘫痪侧转移重心的能力提高了。总之，在带有空间操作的虚拟现实中进行 VST 可改善左侧偏瘫脑卒中患者的空间认知和站立平衡能力。
期刊介绍：
Neurocase is a rapid response journal of case studies and innovative group studies in neuropsychology, neuropsychiatry and behavioral neurology that speak to the neural basis of cognition. Four types of manuscript are considered for publication: single case investigations that bear directly on issues of relevance to theoretical issues or brain-behavior relationships; group studies of subjects with brain dysfunction that address issues relevant to the understanding of human cognition; reviews of important topics in the domains of neuropsychology, neuropsychiatry and behavioral neurology; and brief reports (up to 2500 words) that replicate previous reports dealing with issues of considerable significance. Of particular interest are investigations that include precise anatomical localization of lesions or neural activity via imaging or other techniques, as well as studies of patients with neurodegenerative diseases, since these diseases are becoming more common as our population ages. Topic reviews are included in most issues.
