摘　　要：基于运动意图的脑-机接口(BCI)对人体运动功能增强、替代和康复具有重要研究意义与应用价值。其中,运动想象(MI)是最常用的表征运动意图的BCI范式。然而,传统MI-BCI通常仅实现不同肢体部位运动意图解码,且识别正确率较低,制约着精细运动控制与康复效果。针对上述问题,近年来研究者在单一肢体特定部位、运动学与动力学意图诱发头皮脑电编解码以及运动意图错误相关电位检测3个方面开展了一系列有意义的探索,并在高自由度的运动指令控制和面向卒中患者的临床康复应用方面取得了较大的研究成果。该文从运动意图的头皮脑电(EEG)编解码相关范式及其BCI应用两个方面综述了本领域研究进展,并探讨当前研究存在的问题和可能的解决方案,以期促进运动意图BCI技术的深入研究及开发应用。Movement intention based Brain-Computer Interfaces(BCIs)have important research significance and application value in motor enhancement,replacement and rehabilitation.Among them,Motor Imagery(MI)is the most commonly used BCI paradigm to represent motor intention.However,traditional MI-BCIs usually focus on the recognition of the intention of different limbs,and the classification accuracies are relatively low,which restricts fine motor control and rehabilitation.To solve the above problems,in recent years,researchers have carried out a series of meaningful explorations in coding and decoding of scalp ElectroEncephaloGram(EEG)from three aspects:specific parts of a single limb movement intention,kinematic and kinetics intention,and mismatch between movement and expectation.On the basis of the above research,some typical applications to high freedom motor control and stroke rehabilitation have been developed.The research progress in this field from the related paradigms of scalp EEG coding and decoding of motor intention and its BCI application is reviewed.Besides,the existing challenges and possible solutions are discussed,considering to promote the in-depth research and application of motor intention based BCIs.
