大多数中风患者患有运动和感觉功能障碍以及中枢性面瘫的组合。需要专门的康复训练来恢复这些功能。目前的研究重点是开发刺激和直接的康复训练过程，使患者在出院后坚持在家训练。本研究提出在虚拟实境游戏中，借由不同的脸部表情，并辅以触觉回馈，控制虚拟物件完成指定的任务，以提升病患参与脸部肌肉运动的积极性，并改善其姿势知觉与平衡能力。运动、感觉和面部功能障碍的不同康复训练首次结合在一个虚拟现实游戏中。建议的触觉反馈装置进行建模，仿真和表征。进行了用户研究，以验证拟议的系统。实验结果表明，该脑卒中综合康复虚拟现实游戏能够实现设计的各项功能。增加的触觉反馈通过将轨迹偏差降低22.57%来增强具有面部表情的飞机控制的性能。这意味着所提出的游戏可以提高用户的表现，从而吸引他们进行更多的培训。
Most stroke patients suffer from a combination of motor and sensory dysfunction and central facial paralysis. Specific rehabilitation training is required to restore those functions. Current research focuses on developing stimulating and straightforward rehabilitation training processes so that patients adhere to the training at home after hospital release. This study proposes enhancing patients’ enthusiasm to participate in facial muscle exercises and improving their postural perception and balance by controlling virtual objects to complete assigned tasks in virtual reality games using different facial expressions with the assistance of haptic feedback. The different rehabilitation exercises for motor, sensory, and facial dysfunctions were combined in one virtual reality game for the first time. The proposed haptic feedback device was modeled, simulated, and characterized. A user study was conducted to validate the proposed system. The experiment result shows that all the designed functions of the comprehensive stroke rehabilitation virtual reality game can be achieved. The added haptic feedback enhances the performance of the aircraft control with facial expressions by lowering the trajectory deviation by 22.57%. This implies that the proposed game may improve users' performance, thus attracting them to conduct more training.
