This study examines the difference in application times for routine electroencephalography (EEG) utilizing traditional electrodes and a "dry electrode" headset. The primary outcome measure was the time to interpretable EEG (TIE). A secondary outcome measure of recording quality and interpretability was obtained from EEG sample review by two blinded clinical neurophysiologists. With EEG samples obtained from 10 subjects, the average TIE for the "dry electrode" system was 139s, and for the conventional recording 873s (p<0.001). The results support the hypothesis that such a "dry electrode" system can be applied with more than an 80% reduction in the TIE while still obtaining interpretable EEG.
本研究考察了使用传统电极和“干电极”耳机进行常规脑电图（EEG）的应用时间差异。主要结局指标是可解释脑电图（TIE）的时间。通过两位盲法临床神经生理学家对 EEG 样本进行回顾，获得了记录质量和可解释性的次要结局指标。在对 10 名受试者的 EEG 样本进行分析后，“干电极”系统的平均 TIE 为 139s，而常规记录的 TIE 为 873s（p<0.001）。结果支持这样一种假设，即这种“干电极”系统可以将 TIE 减少 80%以上，同时仍然获得可解释的 EEG。
