Table_1_HomeCoRe system for telerehabilitation in individuals at risk of dementia: A usability and user experience study.pdf

BackgroundTelerehabilitation has enabled a broader application of cognitive rehabilitation programs. We have recently developed HomeCoRe, a system for supporting cognitive intervention remotely with the assistance of a family member. The main goal of the present study was to determine usability and user experience of HomeCoRe in individuals at risk of dementia and in their family members. The association between subjects’ technological skills and main outcome measures was evaluated as well.
MethodsFourteen individuals with subjective cognitive decline (SCD) or mild neurocognitive disorder (mNCD) were recruited to participate in this pilot study. All participants received a touch-screen laptop implemented with the HomeCoRe software. The intervention consisted of 18 sessions and included a patient-tailored adaptive protocol of cognitive exercises. Usability was assessed in terms of treatment adherence and participants’ performance across sessions; user experience via self-reported questionnaires and a descriptive diary.
ResultsUsability and user experience were overall satisfactory and suggested usability, pleasantness, and high motivation while using HomeCoRe. Technological skills correlated only with the perceived ability to start and/or perform exercises autonomously.
DiscussionThese results, although preliminary, suggest that the usability and user experience of HomeCoRe are satisfactory and independent of technological skills. These findings encourage wider and more systematic use of HomeCoRe to overcome the current limitations of in-person cognitive rehabilitation programs and to reach more individuals at risk of dementia.

背景
远程康复（Telerehabilitation）已推动认知康复方案的应用边界进一步拓展。本研究团队近期开发了HomeCoRe系统，一款可在家属协助下开展远程认知干预的支持平台。本研究的首要目标为评估HomeCoRe针对痴呆风险人群及其家属的可用性与用户体验，同时分析受试者的技术能力与主要结局指标间的关联。

方法
本先导性研究共招募14名存在主观认知下降（Subjective Cognitive Decline, SCD）或轻度神经认知障碍（Mild Neurocognitive Disorder, mNCD）的受试者。所有参与者均获配预装HomeCoRe软件的触屏笔记本电脑。干预方案包含18次训练疗程，采用针对个体患者定制的适应性认知训练协议。可用性通过治疗依从性与受试者各疗程的表现进行评估；用户体验则通过自陈式问卷与描述性日志开展调研。

结果
整体而言，HomeCoRe的可用性与用户体验均表现优异，使用者在系统使用过程中展现出良好的易用性、愉悦感与较高的参与动机。技术能力仅与受试者自主启动和/或完成训练任务的感知能力存在显著相关。

讨论
尽管本研究结果尚属初步，但已证实HomeCoRe的可用性与用户体验均令人满意，且不受受试者自身技术能力的影响。该研究结果为HomeCoRe的规模化、系统化推广应用提供了支撑，可弥补当前线下认知康复方案的局限性，惠及更多痴呆风险人群。
