先前在交互式多模式环境中设计的神经康复生物反馈系统已经证明了让中风患者参与以任务为导向的神经运动康复的潜力。本报告探讨了基于多媒体的生物反馈系统的新概念和替代设计。在该系统中,通过运动参数的抽象表示构建了新的交互式多模态环境。场景图像或图片及其清晰度和方向用于反映手臂运动和与目标的相对位置,而不是动画手臂。多个生物反馈参数被分为不同的层次级别。每个运动参数对性能的重要性。针对这些参数开发了一种新的量化测量方法,以实时和离线评估患者的表现。这些参数通过各种不同乐器的视觉和听觉呈现相结合来表示。总体而言,新设计系统的目标是探索交互式虚拟环境中哪些信息以及如何反馈信息可以增强感觉运动整合,从而促进基于虚拟环境的治疗干预的有效设计和应用。
A previous design of a biofeedback system for Neurorehabilitation in an interactive multimodal environment has demonstrated the potential of engaging stroke patients in task-oriented neuromotor rehabilitation. This report explores the new concept and alternative designs of multimedia based biofeedback systems. In this system, the new interactive multimodal environment was constructed with abstract presentation of movement parameters. Scenery images or pictures and their clarity and orientation are used to reflect the arm movement and relative position to the target instead of the animated arm. The multiple biofeedback parameters were classified into different hierarchical levels w.r.t. importance of each movement parameter to performance. A new quantified measurement for these parameters were developed to assess the patient's performance both real-time and offline. These parameters were represented by combined visual and auditory presentations with various distinct music instruments. Overall, the objective of newly designed system is to explore what information and how to feedback information in interactive virtual environment could enhance the sensorimotor integration that may facilitate the efficient design and application of virtual environment based therapeutic intervention.
