The aim of this study was to evaluate the accuracy of a novel single-channel, electroencephalography-based wearable forehead sleep recorder (UMindSleep) to assess sleep staging and oxygen desaturation.<h4>Methods</h4>Two hundred and three Chinese adults recruited from a sleep medicine center underwent an overnight study wearing UMindSleep and PSG simultaneously. Sleep parameters including sleep staging and oxygen desaturation index were compared between UMindSleep and PSG.<h4>Results</h4>A total of 195,349 valid epochs from 197 participants (171 with obstructive Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine711-718https://www.ebi.ac.uk/biostudies/studies/S-EPMC10071378biostudies-literatureValidation of a wearable forehead sleep recorder against polysomnography in sleep staging and desaturation events in a clinical sample.PMC10071378Jin XZhang JChen XHo KWWei YCheng HfalseValidation of a wearable forehead sleep recorder against polysomnography in sleep staging and desaturation events in a clinical sample.<h4>Study objectives</h4>Wearable sleep recording devices may be a helpful alternative method for polysomnography (PSG) due to their higher accessibility and comfort as well as lower cost, but their validities need to be examined.
