大脑在想象或执行身体运动时产生的运动相关皮质电位(MRCPs)因富含大量运动信息、有较严格的锁时和锁相特征而有利于揭示人体运动神经机制、指导运动康复训练以及疗效评价,故受到运动康复领域研究人员的关注.尤其近年随着基于脑电(EEG)的脑-机接口(BCI)技术在康复领域应用的快速发展,利用MRCPs提取大脑运动信息特征逐渐成为运动康复型BCI的研究热点.本文介绍了MRCPs信号的3个时段分量特点及与之对应的皮质激活区,并从运动意图检测、运动参数识别、运动神经机制探索和康复训练效果评价4个方面综述了将MRCPs信号检测和特征解码用于运动康复领域的研究现状,总结归纳了存在问题并分析了未来MRCPs在康复医学中应用的可行性.笔者认为融合MRCPs与其他运动特征信息用于指导运动康复训练实践应是未来运动康复领域发展的主要趋势.
The motor-related cortical potentials (MRCPs) produced by the brain in imagining or performing physical exercises are beneficial to revealing the motor mechanism of the human body, guiding exercise rehabilitation training, and evaluating the curative effect due to the abundant movement information, more stringent lock-up and phase-locking features , So it is concerned by the researchers in the field of sports rehabilitation.In recent years, with the rapid development of EEG-based brain-computer interface (BCI) technology in the field of rehabilitation, the use of MRCPs to extract brain motion information features has gradually become a sports rehabilitation BCI research hot spots.This paper introduces the MRCPs signal characteristics of the three time segments and the corresponding cortical activation area, and from the motion intent detection, motion parameter recognition, motor neurological mechanism and evaluation of rehabilitation training effects are reviewed in four aspects will be reviewed MRCPs signal detection and feature decoding for the field of sports rehabilitation research status, summed up the existing problems and analyzed the feasibility of future MRCPs in the application of rehabilitation medicine.I believe that the integration of MRCPs and other motor characteristics of information used to guide sports rehabilitation training practice Should be the future development of sports rehabilitation in the main trend.
