The HOME project is intended to provide evidence of diagnostic and therapeutic yield of a patient-controlled EEG home-monitoring for neurological outpatients.
This study evaluated the technical and practical usability and efficacy of a new portable dry-electrode EEG recorder in comparison to conventional EEG devices based on technical assessments and inter-rater comparisons of EEG record examinations of office-based practitioners and two experienced neurologists.
The technical assessment was based on channel-wise comparisons of band power values derived from power spectra as observed in two recording modalities. Slight yet significant differences were observed only in the Delta-frequency band (1.5-4 Hz). The fraction of automatically detected artifact segments was larger in the new portable recordings than in conventional recordings (20% vs. 11%, median). Overall, 93% of raters' stated diagnostic findings gathered from conventional devices were concordant with stated diagnostic findings gathered from the new portable device.
The new EEG device was shown to have technical comparability to and a high concordance rate of diagnostic findings with conventional EEG devices.
The new portable dry-electrode EEG device is suitable to meet the HOME projects' goal of establishing a patient-controlled EEG home-monitoring in the routine care of neurological outpatients.

HOME 项目旨在为神经科门诊患者的患者自控式脑电图家庭监测提供诊断和治疗效果的证据。
本研究通过对基于办公室医生和两位经验丰富的神经科医生的脑电图记录检查的技术评估和观察者间比较，评估了一种新型便携式干电极脑电图记录仪在技术和实际可用性及有效性方面与传统脑电图设备相比的情况。
技术评估基于两种记录模式下从功率谱中观察到的频带功率值的通道比较。仅在 Delta 频带（1.5-4 Hz）中观察到了轻微但有统计学意义的差异。新便携式记录中的自动检测到的伪迹段比例大于传统记录（20%比 11%，中位数）。总体而言，93%的常规设备记录的评估者诊断结果与新型便携式设备记录的诊断结果一致。
新型脑电图设备在技术上与传统脑电图设备具有可比性，且诊断结果的一致性率较高。
新型便携式干电极脑电图设备适合满足 HOME 项目在神经科门诊患者常规护理中建立患者自控式脑电图家庭监测的目标。
