摘要

一些睡眠障碍的特征是睡眠中周期性的腿部运动,包括不宁腿综合征,这可能表明在其他健康个体中睡眠中断。目前测量睡眠期间腿部周期性运动的技术是有限的。多导睡眠图和一些家庭睡眠测试使用表面肌电图来测量胫骨前肌的电活动。活动记录仪使用3轴加速度计来测量脚踝的运动。肌电图忽略了涉及其他腿部肌肉的周期性腿部运动,并且由于需要携带信号的电线而显得突兀。基于活动仪的设备需要踝关节的大幅度运动来检测腿部运动(忽略了大量更细微的腿部运动),并且可以在多种配置中佩戴,从而妨碍了精确测量。这些限制导致它们没有被采纳为治疗几种睡眠障碍的标准。在这项研究中,我们开发了RestEaze睡眠评估工具,作为一种踝关节穿戴式可穿戴设备,它结合了电容传感器和6轴惯性测量单元,以精确测量睡眠期间的周期性腿部运动。这种独特的传感器组合和设备的形状因素解决了当前睡眠测量技术中周期性腿部运动的局限性。收集的试点数据显示,在异质参与者样本和高可用性评级中,多导睡眠图具有高度相关性。RestEaze有望为临床医生、研究人员和患者更好地了解睡眠提供生态学上有效的、纵向的腿部运动测量。

RestEaze: An Emerging Technology to Characterize Leg Movements During Sleep
Several sleep disorders are characterized by periodic leg movements during sleep including Restless Leg Syndrome, and can indicate disrupted sleep in otherwise healthy individuals. Current technologies to measure periodic leg movements during sleep are limited. Polysomnography and some home sleep tests use surface electromyography to measure electrical activity from the anterior tibilias muscle. Actigraphy uses 3-axis accelerometers to measure movement of the ankle. Electromyography misses periodic leg movements that involve other leg muscles and is obtrusive because of the wires needed to carry the signal. Actigraphy based devices require large amplitude movements of the ankle to detect leg movements (missing the significant number of more subtle leg movements) and can be worn in multiple configurations precluding precision measurement. These limitations have contributed to their lack of adoption as a standard of care for several sleep disorders. In this study, we develop the RestEaze sleep assessment tool as an ankle-worn wearable device that combines capacitive sensors and a 6-axis inertial measurement unit to precisely measure periodic leg movements during sleep. This unique combination of sensors and the form-factor of the device addresses current limitations of periodic leg movements during sleep measurement techniques. Pilot data collected shows high correlation with polysomnography across a heterogeneous participant sample and high usability ratings. RestEaze shows promise in providing ecologically valid, longitudinal measures of leg movements that will be useful for clinicians, researchers, and patients to better understand sleep.
