Study on Cognitive Rehabilitation using Virtual Reality

我们利用虚拟现实技术开发了一个用于认知康复的虚拟购物任务(VST)。我们使用触摸屏作为界面，在虚拟商场中安排了四个具体项目的购物任务。本研究的目的是通过与其他神经心理学测验/问卷的比较，阐明VST的意义；2)VST在包括失语症患者在内的脑损伤患者中的适用性。VST上的一些变量与日常记忆、注意力和执行功能的常规评估分数相关。患者的平均参考提示次数和平均运动次数显著大于对照组，平均总时间显著长于对照组。结果表明，VST能够评估脑损伤患者的日常记忆、注意力和执行功能。

We have developed a Virtual Shopping Task (VST) using virtual reality technology for cognitive rehabilitation. We used a touch screen as the interface and arranged shopping tasks with four specific items in virtual shopping mall. The objective of this study was to clarify 1) the significance of VST by comparing VST with other neuropsychological tests/questionnaires, 2) the applicability of VST to brain-damaged patients including aphasic patients. Some variables on VST correlated with the scores of conventionalassessments about everyday memory , attention and executive functions. The mean number of times referring to hints and the mean number of movements were significantly larger for the patients, and the mean total time was significantly longer for the patients than for the controls. The results suggest that VST is able to evaluate the ability of everyday memory , attention and executive functions in patients with brain damage.
