本研究的主要目的是回顾和总结最近的研究结果与慢性疼痛的个人脑电图模式。我们还讨论了最近的进展，在使用定量脑电图（qEEG）的病理生理学和生物心理社会因素的评估参与其维护随着时间的推移。数据收集于2014年2月至2015年7月在PubMed、SciELO和PEDro数据库中进行。横断面研究和纵向研究的数据，以及涉及慢性疼痛参与者的临床试验纳入最终分析。我们与慢性疼痛相关的主要发现是休息时θ和α EEG功率的增加，以及感觉刺激和认知任务后诱发电位振幅的降低。这篇综述表明，qEEG可以被认为是一个简单和客观的工具，研究慢性疼痛的大脑机制，以及识别慢性疼痛的具体特征。此外，结果表明，qEEG可能是一个相关的结果指标，用于评估治疗研究的变化。
The main objective of this study is to review and summarize recent findings on electroencephalographic patterns in individuals with chronic pain. We also discuss recent advances in the use of quantitative Electroencephalography (qEEG) for the assessment of pathophysiology and biopsychosocial factors involved in its maintenance over time. Data collection took place from February 2014 to July 2015 in PubMed, SciELO and PEDro databases. Data from cross-sectional studies and longitudinal studies, as well as clinical trials involving chronic pain participants were incorporated into the final analysis. Our primary findings related to chronic pain were an increase of theta and alpha EEG power at rest, and a decrease in the amplitude of evoked potentials after sensory stimulation and cognitive tasks. This review suggests that qEEG could be considered as a simple and objective tool for the study of brain mechanisms involved in chronic pain, as well as for identifying the specific characteristics of chronic pain condition. In addition, results show that qEEG probably is a relevant outcome measure for assessing changes in therapeutic studies.
