This report describes a reliability study using a prototype computer-simulated virtual environment to assess basic daily living skills in a sample of persons with traumatic brain injury (TBI). The benefits of using virtual reality in training for situations where safety is a factor have been established in defense and industry, but have not been demonstrated in rehabilitation.
Thirty subjects with TBI receiving comprehensive rehabilitation services at a residential facility.
An immersive virtual kitchen was developed in which a meal preparation task involving multiple steps could be performed. The prototype was tested using subjects who completed the task twice within 7 days.
The stability of performance was estimated using intraclass correlation coefficients (ICCs). The ICC value for total performance based on all steps involved in the meal preparation task was .73. When three items with low variance were removed the ICC improved to .81. Little evidence of vestibular optical side-effects was noted in the subjects tested.
Adequate initial reliability exists to continue development of the environment as an assessment and training prototype for persons with brain injury.
本报告描述了一项可靠性研究，该研究使用原型计算机模拟虚拟环境来评估创伤性脑损伤（TBI）患者样本的基本日常生活技能。在国防和工业领域，使用虚拟现实进行安全因素相关培训的益处已得到证实，但在康复领域尚未得到验证。
30名在住院机构接受综合康复服务的TBI患者。
开发了一个沉浸式虚拟厨房，在其中可以执行涉及多个步骤的 meal preparation任务。该原型由在7天内完成该任务两次的受试者进行测试。
使用组内相关系数（ICC）估计性能的稳定性。基于meal preparation任务中涉及的所有步骤的总性能的ICC值为0.73。当去除三个方差较小的项目时，ICC提高到0.81。在测试的受试者中几乎没有发现前庭视觉副作用的证据。
存在足够的初始可靠性，可以继续将该环境开发为脑损伤患者的评估和训练原型。
