Actigraphy-based sleep estimation in adolescents and adults: a comparison with polysomnography using two scoring algorithms

Abstract

The two actigraphs provided comparable and accurate data compared to PSG, although both poorly identified wake episodes (i.e., had low specificity). Use of actigraphy scoring algorithm influenced the mean bias and level of agreement in sleep-wake times estimates. The GT3X+, when analyzed by the Cole-Kripke, but not the Sadeh algorithm, provided comparable data to the AWS.
