摘要:

腦機(jī)接口(brain computer interface,BCI)是一項(xiàng)不依賴大腦常規(guī)信息通路就可實(shí)現(xiàn)與外界環(huán)境交流的技術(shù),通過(guò)該技術(shù)可在人腦與計(jì)算機(jī)或其他電子設(shè)備之間建立一種直接的聯(lián)系,使人不依賴正常的骨骼肌肉系統(tǒng)就可直接控制外部設(shè)備,這就為那些思維正常但有嚴(yán)重功能障礙的患者帶來(lái)了新的希望。近20年來(lái)BCI實(shí)現(xiàn)了從無(wú)到有、腦電信號(hào)從單一到混合等技術(shù)上的飛速發(fā)展,另外隨著識(shí)別任務(wù)數(shù)目的增多、信息傳輸率及識(shí)別準(zhǔn)確性的提高,BCI也逐漸走出了實(shí)驗(yàn)室,朝著實(shí)時(shí)、實(shí)用的方向發(fā)展。本文主要針對(duì)基于EEG的單一模式和混合模式腦機(jī)接口的研究現(xiàn)狀及其在康復(fù)醫(yī)學(xué)中的實(shí)際應(yīng)用進(jìn)行了綜述,總結(jié)了不同模式BCI的功能特點(diǎn)及其在康復(fù)醫(yī)學(xué)領(lǐng)域的應(yīng)用潛力,以期促進(jìn)BCI在康復(fù)應(yīng)用中進(jìn)一步發(fā)展,并提高目前康復(fù)治療技術(shù)。

Brain-computer interface (BCI) is a technology independent of routine brain output ways that can communicate with the external enviroment,it provides a direct communication pathway between the brain and external devices so as to exert control over those devices independent of routine peripheral nerves and organization system,this is especially significant for those patients who have normal thought but with severe dysfunction.In the past 20 years,BCI have realized rapid development,from scratch on technology and from single to max on the model.Moreover,with the number of recognition tasks incread and the improvement of information transmission rate and accuracy,researchers are trying to make the BCI system possess the characteristics of real-time and become more practical.This paper reviews the research progress of single model and mixed model of EEG-based BCI and its practical application in the rehabilitation medicine.Through the summary on the functions and characters of different model BCI systems,its potential applications in the rehabilitation medicine are found,the researchers hope that can promote the further development of rehabilitative applications and improve the treatment technology of rehabilitation.
