Self-applied electrode set provides a clinically feasible solution enabling EEG recording in home sleep apnea testing

Home sleep apnea testing (HSAT) without electroencephalography (EEG) recordings is increasingly used as an alternative to in-laboratory polysomnography for the diagnosis of obstructive (OSA). However, EEG, electrooculography (EOG), and chin electromyography (EMG) recordings, OSA severity may be significantly underestimated. Although several ambulatory EEG systems have been recently introduced, no patient-applied including EOG, EMG suitable home are currently in clinical use. We developed pre-clinically tested a self-applied electrode set (AES), consisting frontal EMG, subjects with possible bruxism. Now, this feasibility study, we investigated signal scorability usability AES self-administered assessment approach supplementing conventional HSAT device. also how diagnostic parameters changed when utilizing AES. Thirty-eight patients (61 % male, 25-78 years) suspicion conducted single-night, portable device (Nox A1, Nox Medical, Reykjavik, Iceland) supplemented Only one recording failed. The use signals data analysis affected median AHI, increasing it from 9.4 12.7 events/h (p<0.001) compared HSAT. Also, eight patients, class worse. Perceived ease was well line that previously found among healthy volunteers. These results suggest provides easy, clinically feasible solution record part
