研究目的:

本研究旨在探讨不同示教模式对卒中后患者上肢运动评估表现及认知负荷的影响,重点比较第一人称的混合现实示教(Mixed Reality Demonstration, MRD)与第三人称的视频演示(Video Demonstration, VD)两种评估方式的差异。  

Objectives of Study:

The present study aims to systematically investigate the effects of different demonstration modes on upper limb motor performance and cognitive load in post-stroke patients. Specifically, it compares a first-person mixed reality demonstration (MRD) with a traditional third-person video demonstration (VD) in terms of kinematic performance, physiological indices of cognitive load, and subjective experience. The study further aims to establish a mixed reality–based upper limb assessment paradigm and to explore how an immersive, interactive environment influences assessment feasibility and reliability in stroke patients with varying levels of cognitive function.
