基于VR的老年癌症患者认知评估和沉浸式怀旧疗法康复系统的设计与应用探索

Design and pilot application of cognitive assessment and immersive reminiscence therapy rehabilitation system for elderly cancer patients based on VR technology

目的 :为应对全球老龄化以及满足老年癌症患者日益增长的认知康复需求,研发基于虚拟现实(VR)技术的老年癌症患者认知评估和沉浸式怀旧疗法康复系统。方法 :该系统包括VR认知评估和康复训练,其中VR认知评估包括癌症相关认知障碍和轻度痴呆评估两个模块;VR认知康复训练包括一般认知康复训练和针对有轻度痴呆风险患者的沉浸式怀旧疗法两个模块。在37名老年受试者中进行了轻度痴呆评估。结果 :通过受试者操作特征(ROC)曲线分析,VR认知测评为9.5分及以下为有轻度痴呆风险。VR轻度痴呆评估过程中未出现与评估和干预相关的不良事件。结论 :将VR技术应用于老年癌症患者中进行轻度痴呆风险的评估是可行和安全的,但VR轻度痴呆风险评估的准确性和沉浸式怀旧疗法的有效性仍需要在老年癌症患者中进行进一步检验。

Objective: With the global aging population and to meet the growing cognitive rehabilitation needs of elderly cancer patients, this preliminary study aimed to design and develop a cognitive rehabilitation system based on Virtual Reality(VR) technology for screening elderly cancer patients’ mild dementia and an immersive reminiscence therapy system. Methods: The system includes VR cognitive assessment and cognitive rehabilitation, VR cognitive assessment includes two modules of cancer-related cognitive impairment assessment and mild dementia screening assessment;and VR rehabilitation includes the general cognitive rehabilitation module and the module of immersive reminiscence therapy. Results: Preliminary applications were conducted among 37 subjects to test the feasibility and safety of the system. By Receiver Operating Characteristic(ROC) curve analysis, this study identified a total VR cognitive test score of 9.5 as threshold for discriminating older adults with mild dementia or not. There were no adverse events related to the VR cognitive assessment and intervention. Conclusion: It can be seen that it is feasible and safe to apply VR technology to the assessment of elderly cancer patients with mild dementia, but the effectiveness of VR mild dementia assessment and immersive reminiscence therapy still needs to be examined among elderly cancer patients.
