摘　　要：慢性疼痛是一种主观感受,难以进行准确的客观评估。脑电图(EEG)能够监测患者大脑生理电信号,时间信号能够反映处理任务时的大脑活动,频率信号可以反映安静状态时的大脑活动。该文综述了慢性疼痛患者脑电时间信号中事件相关电位变化情况、频率信号中不同频段变化情况以及两种信号之间事件相关同步或去同步现象变化情况。Chronic pain is a subjective experience that is difficult to accurately and objectively assess.Electroencephalography(EEG)can record physiological electrical signals generated during brain activity,and time signals reflect brain activity during task processing.The frequency signals reflect quiet brain activity.This paper reviews changes of event-related potential in EEG time signal,changes of different frequency bands in frequency signal and changes of event-related synchronization or desynchronization between the two signals in patients with chronic pain.
