The criteria for electroencephalography (EEG) arousals defined by the American Sleep Disorders Association (ASDA) have recently been criticized because of lack of interobserver agreement. The authors have adopted a scoring method that associates the increase in chin electromyography (EMG) with the occurrence of an \u03b1-rhythm in all sleep stages (Universit\u00e9 Catholique de Louvain (UCL) definition of arousals). The aim of the present study was to compare the two scoring definitions in terms of agreement and repeatability and the time taken for scoring in patients with obstructive sleep apnoea syndrome (OSAS) of varying severity.<\/jats:p><jats:p>Two readers using both ASDA and UCL definitions scored twenty polysomnographies (PSGs) each on two occasions. The PSGs were chosen retrospectively to represent a wide range of arousal index (from 6\u201382) in OSAS patients.<\/jats:p><jats:p>There was no difference in the arousal indices between readers and between scoring methods. The mean\u00b1sd difference between the two definitions (the bias) was 1.1\u00b13.76 (95% confidence interval: \u22120.66\u20132.86). There was a strong linear relationship between the arousal index scored with the two definitions (r=0.981, p&lt;0.001). Mean\u00b1sd scoring duration was significantly shorter for UCL than for ASDA definitions (18.5\u00b15.4<jats:italic>versus<\/jats:italic>25.3\u00b16.6 min, p&lt;0.001).<\/jats:p><jats:p>In conclusion, it has been found that in obstructive sleep apnoea syndrome patients, the American Sleep Disorders Association and Universit\u00e9 Catholique de Louvain definitions were comparable in terms of agreement and repeatability.<\/jats:p>","DOI":"10.1183\/09031936.01.17407230","type":"journal-article","created":{"date-parts":[[2002,10,11]],"date-time":"2002-10-11T18:37:23Z","timestamp":1034361443000},"page":"723-727","source":"Crossref","is-referenced-by-count":37,"title":["Sleep fragmentation: comparison of two definitions of short arousals during sleep in OSAS patients"],"prefix":"10.1183","volume":"17","author":[{"given":"M.V.","family":"Smurra","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Dury","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Aubert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.O.","family":"Rodenstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Liistro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2001,4,1]]},"reference":[{"key":"2024101808414304000_17.4.723.1","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1093\/sleep\/7.1.18","volume":"7","year":"1984","journal-title":"Sleep"},{"key":"2024101808414304000_17.4.723.2","doi-asserted-by":"crossref","first-page":"174","DOI":"10.1093\/sleep\/15.2.174","volume":"15","year":"1992","journal-title":"Sleep"},{"key":"2024101808414304000_17.4.723.3","doi-asserted-by":"crossref","first-page":"1123","DOI":"10.1152\/jappl.1993.74.3.1123","volume":"74","year":"1993","journal-title":"J Appl Physiol"},{"key":"2024101808414304000_17.4.723.4","unstructured":"Arousal responses to respiratory stimuli during sleep.
