人體睡眠監(jiān)測報(bào)告PPT課件

1、1,Validating Actigraphy as a Measure of Sleep for Preschool Children 驗(yàn)證Actigraphy是一種對學(xué)前兒童的睡眠的測量,祝楠楠 14723539,2,文獻(xiàn)作者,來源： Journal of Clinical Sleep Medicine, Vol. 9, No. 7, 2013 （臨床睡眠醫(yī)學(xué)雜志,3,課題背景,1）測量成人睡眠監(jiān)測的算法比較成熟，而對于兒童來說，現(xiàn)在的算法不確定是否適合。 （2）測試工具都是佩戴式，或者入侵式，而兒童睡覺不安穩(wěn)，容易活動(dòng)，造成數(shù)據(jù)不準(zhǔn)確，所以，發(fā)展應(yīng)用于兒童的算法很重要,4,背景介紹,Sl

2、eep is considered to be of paramount importance for brain development during the first two years of life. In fact, children spend over half of their first two years of life sleeping, with daily sleep duration decreasing from 14.5 to about 13 hours between 6 months and 2 years of age.In the preschool

3、 years, daily sleep needs remain high, decreasing from 13 hours at 2 years to about 11 hours at 5 years.During infancy and childhood, frequent night awakenings or diffi culty falling asleep areamong the most frequent developmental complaints,5,課題目的,驗(yàn)證三種算法，是否適合學(xué)前兒童，比較他們的有效性，且前提是佩戴的儀器是驗(yàn)證過的。此課題旨在通過研究，了

4、解學(xué)前兒童睡眠狀況，為后續(xù)提高學(xué)前兒童睡眠質(zhì)量和促進(jìn)學(xué)前兒童大腦發(fā)育尋找辦法,6,PSG,The polysomnography (PSG) is the gold standard for measuring sleep, it requires considerable equipment and technical resources. 多導(dǎo)睡眠圖、多導(dǎo)睡眠監(jiān)測,7,Actigraphy(體動(dòng)記錄儀,8,Actiwatch,9,METHODS,Subjects(被試) Twelve children (4 boys, 8 girls) aged from 2 to 5 years (M

5、= 3.1, SD = 1.0) participated in this study. None had sleep problems, according to their parents,10,Procedures: 同一天，讓12個(gè)合格兒童回到家，讓技術(shù)員和助理研究員在小孩睡覺前一個(gè)小時(shí)，給佩戴儀器（腳踝和手腕），并測試PSG的記錄器和Actigraph正常工作，并使技術(shù)員和助理研究員離開，第二天拆除回收儀器和數(shù)據(jù),11,分析,數(shù)據(jù)分析兩種協(xié)議： （1）an epoch-by-epoch agreement analysis （2）a sleep variables concordan

6、ce analysis 統(tǒng)計(jì)分析用到四組數(shù)：PSG, ACT40, ACT80, and AlgoSmooth 測試方式分析：ankle, raw wrist, and adjusted wrist,12,ACT40, ACT80的算法,AlgoSmooth的算法要點(diǎn)： （1）計(jì)數(shù)大于0的連續(xù)2分鐘內(nèi)有數(shù)據(jù)100，被定義為清醒狀態(tài) （2）連續(xù)3計(jì)數(shù)為0定義為重返睡眠狀態(tài),13,14,RESULTS,15,16,17,DISUSSION,Results clearly showed that the Actiwatch-L(philips制造的Actigraphy) is better able to detect sleep than to detect wake. ACT80和AlgoSmooth相對于ACT40加強(qiáng)了對睡眠的監(jiān)測，降低了對不眠的監(jiān)測。 ACT80和ACT40高估清醒，AlgoSmooth低估清醒,18,Despite the weak detection of wakefulness, Actiwatch-L appears
