There is a growing body of evidence regarding the clinical significance of PLMS, and this movement disorder is of concern in both clinical and scientific contexts. Leg actigraphy is a convenient and promising method for screening periodic limb movements in sleep (PLMSs). This study aims to demonstrate the reliability of the SOMNOwatch™ actigraph for detecting periodic limb movements in sleep. Twenty-eight patients, referred to a sleep laboratory for various sleep problems, underwent nocturnal polysomnography with simultaneous one-sided actigraphy using the SOMNOwatch™ actigraph. Recordings of leg movements obtained from both methods were manually scored, calculating the periodic limb movement index (PLMI). The agreement between the methods was assessed through correlation analysis and event-by-event comparison. The correlation between the PLMI derived from PSG and SOMNOwatch™ was high and statistically significant (r = 0.98, < 0.0001). The SOMNOwatch™ demonstrated a sensitivity of 86.7% and a specificity of 92.3% in detecting PLMS. Similarly, for detecting patients with a PLMI equal to or greater than 15, the sensitivity was 85.7%, and the specificity was 95.2%.
关于不宁腿综合征（PLMS）的临床意义，现有越来越多的证据，并且这种运动障碍在临床和科研环境中都备受关注。腿部活动记录仪是一种用于筛查睡眠期周期性肢体运动（PLMSs）的便捷且有前景的方法。本研究旨在证明SOMNOwatch™活动记录仪检测睡眠期周期性肢体运动的可靠性。28名因各种睡眠问题被转诊至睡眠实验室的患者，使用SOMNOwatch™活动记录仪进行了夜间多导睡眠图检查并同时进行单侧活动记录。从两种方法获得的腿部运动记录均进行人工评分，计算周期性肢体运动指数（PLMI）。通过相关性分析和逐事件比较评估两种方法之间的一致性。来自多导睡眠图（PSG）和SOMNOwatch™的PLMI之间的相关性很高且具有统计学意义（r = 0.98，<0.0001）。SOMNOwatch™在检测PLMS时的灵敏度为86.7%，特异度为92.3%。同样，对于检测PLMI等于或大于15的患者，灵敏度为85.7%，特异度为95.2%。
