NEW DATA ANALYSIS METHODS FOR ACTIGRAPHY IN SLEEP MEDICINE

描述（由申请人提供）：本研究旨在开发统计和信息学工具，用于分析和可视化与睡眠医学中心患者疲劳相关的体动记录数据。活动记录仪是一种连接在手腕上的类似手表的设备，它使用加速度计在几天内几乎连续地测量运动。美国睡眠医学学会2002年的一份报告定义了使用活动记录仪的实践参数，作为检测健康个体睡眠的有用工具，评估失眠和不宁腿综合征的特定方面，以及诊断和治疗失眠、昼夜节律紊乱和过度嗜睡的详细病史和主观睡眠日记的有用辅助工具。与这些建议同时出现的是对使用体动计作为客观测量疲劳的工具的兴趣增加。随着用于分析这些数据的高端统计方法的改进，体动记录仪有可能成为更重要的客观诊断工具，用于确定疲劳，睡眠异常和评估治疗反应。在神经学和医学的其他特殊领域，体动记录仪可以更有效地使用，包括不宁腿综合征，老年人和疗养院患者，新生儿，婴儿，儿童和青少年，高血压患者，抑郁症或精神分裂症患者，以及无法接近的情况下的个人。公共卫生相关性：随着用于分析体动记录数据的高端统计方法的改进，体动记录有可能在临床医学和研究中变得更加重要，作为确定疲劳、睡眠异常和评估治疗反应的客观诊断工具。在神经学和医学的其他特殊领域，体动记录仪可以更有效地使用，包括不宁腿综合征，老年人和疗养院患者，新生儿，婴儿，儿童和青少年，高血压患者，抑郁症或精神分裂症患者，以及无法接近的情况下的个人。

DESCRIPTION (provided by applicant): The purpose of this study to develop statistical and informatics tools for analyzing and visualizing actigraphy data linked to fatigue in sleep medicine center patients. An actigraph is a watch-like device attached to the wrist that uses an accelerometer to measure movement nearly continuously over several days. An American Academy of Sleep Medicine 2002 report defines the practice parameters for the use of actigraphy as a useful tool for detecting sleep in healthy individuals, assessing specific aspects in insomnia and restless leg syndrome, and a useful adjunct to a detailed history and subjective sleep diary for diagnosing and treating insomnia, circadian-rhythm disorders, and excessive sleepiness. Concurrent with these recommendations is an increased interest in the use of actigraphy as a tool for objectively measuring fatigue. With improved high-end statistical methods for analyzing this data, actigraphy has the potential to become more important as an objective diagnostic tool for determining fatigue, sleep abnormalities and assessing response to treatment. Other special areas of neurology and medicine where actigraphy can be used more effectively include restless leg syndrome, the elderly and nursing home patients with and without dementia, newborns, infants, children, and adolescents, hypertensive individuals, depressed or schizophrenic patients, and individuals in inaccessible situations. PUBLIC HEALTH RELEVANCE: With improved high-end statistical methods for analyzing actigraphy data, actigraphy has the potential to become more important in clinical medicine and research as an objective diagnostic tool for determining fatigue, sleep abnormalities and assessing response to treatment. Other special areas of neurology and medicine where actigraphy can be used more effectively include restless leg syndrome, the elderly and nursing home patients with and without dementia, newborns, infants, children, and adolescents, hypertensive individuals, depressed or schizophrenic patients, and individuals in inaccessible situations.
