- Abstract
There are increasing needs for self-applicable methods assessing sleep in clinical and non-clinical settings. This study aimed to investigate the inter-scorer reliability for the sleep stage scoring and for the sleep variable assessments in the portable electroencephalography (EEG) and electro-oculography (EOG) recording system. Sleep recordings were performed simultaneously with polysomnography (PSG) and portable EEG/EOG recordings in 14 healthy adults. The inter-scorer concordance of the sleep stage scoring was assessed in the two recording methods. Sleep variables were compared between the two methods using the Bland-Altman plots in each scorer. The overall inter-scorer concordance rate of sleep stage scoring for the EEG/EOG data was 85.5 %, and the Cohen's κ was 0.80 ( p < 0.001), being equivalent to those for the PSG data (89.2 %, 0.85, p < 0.001) while that for StageN1 was relatively low (EEG/EOG 60.1 %, PSG 71.7 %). In both scorers, Bland-Altman plots showed that the mean difference between sleep variables obtained from the two systems was within the acceptable range although the inter-class correlations between the two systems were lower for StageN2 or StageR in either scorer. Although the results suggest that the sufficient inter-scorer reliability can be obtained with the EEG/EOG recording system based on manual sleep stage scoring in healthy young adults, the nature of the EEG/EOG recording system can influence the precisions in manually assessing sleep architectures in comparison to PSG.
