目的：比较医疗级和消费级脑电图系统的定量脑电图信号和重测可靠性。方法：在两次研究访视期间，通过两个医用级（B-Alert、Enobio）和两个消费级（Muse、Mindwave）脑电图系统对五名健康受试者采集静息态脑电图。比较了四个系统在闭眼和睁眼条件下的脑电图模式、功率谱密度 (PSD) 和测试/再测试可靠性，重点关注唯一的公共电极 Fp1。 Fp1 PSD 是使用 Welch 的改良周期图方法获得的，并对每次访视的 5 名受试者进行平均。测试/重新测试结果计算为每个 1 秒时期的访问 1/访问 2 Fp1 通道 PSD 的比率。结果：B-Alert、Enobio 和 Mindwave Fp1 功率谱相似。 Muse 显示出功率谱的宽带增加以及重复测试采集中最高的相对变化。由于眨眼和额叶区域的肌肉运动，消费者系统更容易出现伪影。结论：可以从所有四个测试系统中成功收集脑电图数据。尽管应用所需的时间稍长，但医疗系统在数据质量、可靠性和分析深度方面比消费系统具有明显的优势。意义：该评估为明智地选择适合临床试验的脑电图系统提供了证据。
Objectives: To compare quantitative EEG signal and test-retest reliability of medical grade and consumer EEG systems. Methods: Resting state EEG was acquired by two medical grade (B-Alert, Enobio) and two consumer (Muse, Mindwave) EEG systems in five healthy subjects during two study visits. EEG patterns, power spectral densities (PSDs) and test/retest reliability in eyes closed and eyes open conditions were compared across the four systems, focusing on Fp1, the only common electrode. Fp1 PSDs were obtained using Welch's modified periodogram method and averaged for the five subjects for each visit. The test/retest results were calculated as a ratio of Visit 1/Visit 2 Fp1 channel PSD at each 1 s epoch. Results: B-Alert, Enobio, and Mindwave Fp1 power spectra were similar. Muse showed a broadband increase in power spectra and the highest relative variation across test-retest acquisitions. Consumer systems were more prone to artifact due to eye blinks and muscle movement in the frontal region. Conclusions: EEG data can be successfully collected from all four systems tested. Although there was slightly more time required for application, medical systems offer clear advantages in data quality, reliability, and depth of analysis over the consumer systems. Significance: This evaluation provides evidence for informed selection of EEG systemsappropriate for clinical trials.
