Using sleep laboratory polysomnography (PSG) is restricted for the diagnosis of only the most severe sleep disorders due to its low availability and high cost. Home PSG is more affordable, but applying conventional electroencephalography (EEG) electrodes increases its overall complexity and lowers the availability. Simple, self-administered single-channel EEG monitors on the other hand suffer from poor reliability. In this study, we aimed to quantify the reliability of self-administrated home PSG recordings conducted with a newly designed ambulatory electrode set (AES) that enables multichannel EEG, electrooculography, electromyography, and electrocardiography recordings. We assessed the sleep study success rate and technical quality of the recordings performed in subjects with possible sleep bruxism (SB). Thirty-two females and five males aged 39.6 ± 11.6 years (mean±SD) with self-reported SB were recruited in the study. Self-administrated home PSG recordings with two AES designs were conducted (n = 19 and 21). The technical quality of the recordings was graded based on the proportion of interpretable data. Technical failure rate for AES (both designs) was 5% and SB was scorable for 96.9% of all recorded data. Only one recording failed due to mistakes in self-applying the AES. We found that the proportion of good quality self-administrated EEG recordings is significantly higher when multiple channels are used compared to using a single channel. Sleep study success rates and proportion of recordings with high quality interpretable data from EEG channels of AES were comparable to that of conventional home PSG. Self-applicable AES has potential to become a reliable tool for widely available home PSG.
使用睡眠实验室多导睡眠图（PSG）进行诊断仅限于最严重的睡眠障碍，因为其可用性低且成本高。家庭 PSG 更经济实惠，但应用传统的脑电图（EEG）电极会增加其整体复杂性并降低可用性。另一方面，简单的、自我管理的单通道 EEG 监测器则可靠性较差。在这项研究中，我们旨在量化使用新设计的可移动电极套件（AES）进行自我管理的家庭 PSG 记录的可靠性，该套件可进行多通道 EEG、眼电图、肌电图和心电图记录。我们评估了可能患有睡眠磨牙症（SB）的受试者进行的睡眠研究成功率和记录的技术质量。研究纳入了 32 名女性和 5 名男性，年龄 39.6±11.6 岁（均值±标准差），均自述患有 SB。使用两种 AES 设计进行了自我管理的家庭 PSG 记录（n=19 和 21）。根据可解释数据的比例对记录的技术质量进行分级。AES（两种设计）的技术故障率为 5%，可对 96.9%的所有记录数据进行 SB 评分。只有一次记录因 AES 自我应用错误而失败。我们发现，与使用单通道相比，使用多个通道时，自我管理 EEG 记录的高质量比例明显更高。AES 的睡眠研究成功率和 EEG 通道高质量可解释数据的比例与传统家庭 PSG 相当。自我应用的 AES 有可能成为一种可靠的、广泛可用的家庭 PSG 工具。
