研究目的:

本研究旨在评价大语言模型驱动的具身社交机器人即时自适应认知训练干预对轻度认知障碍老年人认知功能的影响,并评估该干预的可行性、安全性、可接受性和依从性。主要目的为比较干预组与对照组在24周干预前后蒙特利尔认知评估量表(MoCA)总分变化的差异。次要目的包括评价干预对记忆、注意、执行功能、情绪状态、训练动机、参与度和依从性的影响,并在机制亚组中探索脑功能连接及血液生物标志物变化与认知改善之间的关系。  

Objectives of Study:

This study aims to evaluate the effects of an LLM-driven embodied social robot-based just-in-time adaptive cognitive training intervention on cognitive function in older adults with mild cognitive impairment, and to assess its feasibility, safety, acceptability, and adherence. The primary objective is to compare the change in Montreal Cognitive Assessment (MoCA) total score from baseline to the end of the 24-week intervention between the intervention and control groups. Secondary objectives include evaluating effects on memory, attention, executive function, emotional status, training motivation, engagement, and adherence, and exploring associations between changes in brain functional connectivity, blood biomarkers, and cognitive improvement in a mechanistic subgroup.

Group:

Intervention group

Sample size:

干预措施:

大语言模型辅助的具身社交机器人即时自适应认知训练,每周3次,每次约45至60分钟,持续24周。系统根据受试者训练表现、反应时间、错误模式及交互状态动态调整训练任务难度、反馈方式和情绪支持策略。

干预措施代码:

Intervention:

LLM-assisted embodied social robot-based just-in-time adaptive cognitive training, three sessions per week, approximately 45 to 60 minutes per session, for 24 weeks. The system dynamically adjusts task difficulty, feedback, and emotional support strategies according to training performance, response time, error patterns, and interaction status.
