Abstract

Objective

To develop a low-cost portable EEG system, with real-time automated guidance, for application in resource-limited areas, to bridge the diagnostic and treatment gap.

Methods

We designed, developed, and produced a low-cost system, which records 27-channel EEG plus ECG and streams the signals to an application on a smartphone, which assesses the quality of the signal and gives feedback to the inexperienced user to correct the poor quality signals and reduce artifacts. The application guides the inexperienced user through the steps of recording routine clinical EEG. The recordings are uploaded to a secure cloud, for telemedicine applications. We recruited 10 participants without prior experience with recording EEG. After a brief training session, the participants recorded EEGs following the guidance from the app, without help from human experts. We assessed the usability of the system, with the System Usability Scale (SUS), and we evaluated the impedances and signal quality of the test EEGs recorded by the inexperienced users.

Results

All users completed the test EEG recordings, and none of the recordings were of insufficient quality for clinical use. The SUS score was 90.3 ± 6.8, and the average quality rating was 8.04.

Significance

The low-cost, portable EEG system, which uses automated, real-time guidance for conducting EEG recordings, enables inexperienced users to record EEGs of a quality sufficient for clinical applications. This system has the potential to provide EEG services in resource-limited areas, and thereby help bridge the diagnostic and therapeutic gap.

用于缩小资源有限地区诊断差距的低成本便携式脑电图设备。

目的：开发一种具有实时自动引导功能的低成本便携式脑电图系统，应用于资源有限的地区：开发一种具有实时自动指导功能的低成本便携式脑电图系统，应用于资源有限的地区，弥补诊断和治疗方面的差距：我们设计、开发并生产了一种低成本系统，该系统可记录 27 个通道的脑电图和心电图，并将信号流传输到智能手机上的应用程序，该应用程序可评估信号质量，并向缺乏经验的用户提供反馈，以纠正质量差的信号并减少伪影。该应用程序可指导缺乏经验的用户完成记录常规临床脑电图的步骤。记录上传到安全云端，用于远程医疗应用。我们招募了 10 名没有脑电图记录经验的参与者。在简短的培训课程后，参与者根据应用程序的指导记录脑电图，无需人工专家的帮助。我们使用系统可用性量表（SUS）评估了系统的可用性，并对没有经验的用户记录的测试脑电图的阻抗和信号质量进行了评估：结果：所有用户都完成了测试脑电图记录，无一记录质量不适合临床使用。SUS 评分为 90.3 ± 6.8，平均质量评分为 8.04：这套便携式脑电图系统成本低廉，使用自动实时指导进行脑电图记录，使缺乏经验的用户也能记录质量足以满足临床应用需要的脑电图。该系统有可能为资源有限的地区提供脑电图服务，从而帮助缩小诊断和治疗差距。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
