To assess selected cognitive functions of persons with traumatic brain injury using a computer-simulated virtual reality environment.
A computer-simulated virtual kitchen was used to assess the ability of 30 patients with brain injury and 30 volunteers without brain injury to process and sequence information. The overall assessment score was based on the number of correct responses and the time needed to complete daily living tasks. Identical daily living tasks were tested and scored in participants with and without brain injury. Each subject was evaluated twice within 7 to 10 days. A total of 30 tasks were categorized as follows: information processing, problem solving, logical sequencing, and speed of responding.
Persons with brain injuries consistently demonstrated a significant decrease in the ability to process information (P = 0.04-0.01), identify logical sequencing (P = 0.04-0.01), and complete the overall assessment (P < 0.01), compared with volunteers without brain injury. The time needed to process tasks, representing speed of cognitive responding, was also significantly different between the two groups (P < 0.01).
A computer-generated virtual reality environment represents a reproducible tool to assess selected cognitive functions and can be used as a supplement to traditional rehabilitation assessment in persons with acquired brain injury.
使用计算机模拟的虚拟现实环境评估创伤性脑损伤患者的特定认知功能。
使用计算机模拟的虚拟厨房评估30名脑损伤患者和30名无脑损伤志愿者处理和排序信息的能力。总体评估分数基于正确反应的数量以及完成日常生活任务所需的时间。对有脑损伤和无脑损伤的参与者进行相同的日常生活任务测试并评分。每个受试者在7至10天内接受两次评估。总共30项任务分类如下：信息处理、问题解决、逻辑排序和反应速度。
与无脑损伤的志愿者相比，脑损伤患者在信息处理能力（P = 0.04 - 0.01）、识别逻辑排序（P = 0.04 - 0.01）和完成总体评估（P < 0.01）方面持续表现出显著下降。处理任务所需的时间，即认知反应速度，两组之间也存在显著差异（P < 0.01）。
计算机生成的虚拟现实环境是评估特定认知功能的可重复工具，可作为后天性脑损伤患者传统康复评估的补充。
