摘要: The last 20 yrs have seen a marked increase in studies utilizing actigraphy free-living environments. aim of the present study is to directly compare two commercially available actigraph devices with concurrent polysomnography (PSG) during daytime nap healthy young adults. Thirty adults, ages 18–31 (mean 20.77 yrs, SD 3.14 yrs) simultaneously wore AW-64 and GT3X+ polysomnographically recorded nap. Mann-Whitney U (M-U) test, intraclass correlation coefficients, Bland-Altman statistic were used total sleep time (TST), onset latency (SOL), wake after (WASO), efficiency (SE) between actigraphs PSG. Epoch-by-epoch (EBE) agreement was calculated determine accuracy, sensitivity, specificity, predictive values for (PVS) (PVW), kappa prevalence- bias-adjusted (PABAK) coefficients. All frequency settings provided by examined. For both actigraphs, EBE analysis found a...
