Quality assessment of electroencephalography obtained from a "dry electrode" system.
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.
