“…Since the publication of the first automatic scoring algorithm for actigraphy by Webster et al (1982), various computer algorithms have been developed to automatically score sleep and wake from the recorded raw actigraphy movement data (see Ancoli-Israel et al, 2003;Littner et al, 2003;Morgenthaler et al, 2007;Thorpy et al, 1995 for an extensive bibliography). Notable among the reported actigraphy algorithms are the ones developed by Sadeh et al (1989Sadeh et al ( , 1994Sadeh et al ( , 1995 covering not only adult normal and abnormal subjects, but also infants, the algorithm of Cole et al (1992), the Actigraph Data Analysis Software (adas) by Jean-Louis et al (1996), the algorithm reported by Sazonov et al (2004) and various commercially available algorithms accompanying the different actimeters available in the market.…”
