【摘要】：针对脑卒中患者的手功能康复,本文介绍一种基于运动想象脑机接口的康复系统。该系统包含3个子系统。离线训练子系统依次呈现黑屏、左/右手动作视频、左/右箭头,分别提示患者休息、准备并指导运动想象、进行运动想象任务,最终将采集的脑电信号(EEG)建立识别模型;在线更新训练子系统依次呈现黑屏、箭头提示,依据建立的模型分析患者EEG信号,控制手部动作视频呈现,同时反馈给患者产生更易识别的EEG信号,建立更有效的识别模型;虚拟现实在线训练子系统在3Dmax中制作训练场景模型、3D人物模型及其手部动画,导入Unity3D中设计控制方式,患者通过手部运动想象,依据有效模型分析其EEG信号,实时控制3D人物手部运动。该系统具有多层次、沉浸感强等特点,为手功能康复提供新方法,同时为家庭化训练奠定基础。
[Abstract]:In view of the hand function rehabilitation of stroke patients, this paper introduces a rehabilitation system based on the motion imaginary brain machine interface, which consists of 3 subsystems. The off-line training subsystem presents the black screen, left / right motion video and left / right arrow. The recognition model was established by the EEG. The online update training subsystem presented the black screen in turn, the arrowhead prompted, analyzed the patient's EEG signal, controlled the hand motion video presentation according to the established model, and feedback to the patient to produce more recognizable EEG signals, and set up a more effective recognition model; the virtual reality online training subsystem was in 3D In the max, the training scene model, the 3D character model and its hand animation are introduced into the Unity3D design control mode. The patient's hand motion picture is imagined by the hand, and the EEG signal is analyzed in real time on the basis of the effective model. The system has a multi level, strong immersion and so on, which provides a new method for the rehabilitation of the hand function, and is also a new method for the rehabilitation of the hand function. At the same time, the system is family oriented. Training lays the foundation.
