Restless sleep disorder has been described in the literature as a disorder affecting children and presenting with large muscle movements during sleep with an index of 5 events/h or more, leading to daytime impairment including sleepiness or behavioral problems. Children with restless sleep disorder have been found to have low ferritin levels. Studies with iron supplementation both oral or intravenous have been shown effective in clinically improving both nighttime and daytime symptoms. However objective data of the improvement is lacking. Repeating polysomnography is expensive, and alternative methods of assessing large muscle movements are needed. In this small case series we present actigraphy results in 3 children with restless sleep disorder collected for 1 week, a week before and 8 weeks after intravenous iron supplementation. Although actigraphy parameters were not highly consistent between our 3 patients, improvement in symptoms tend to parallel sleep parameters in actigraphy.

文中描述了一种不安腿睡眠障碍，这种疾病影响儿童，在睡眠期间出现大肌肉运动，每小时 5 次或更多次，导致日间损害，包括嗜睡或行为问题。患有不安腿睡眠障碍的儿童铁蛋白水平较低。口服或静脉补铁的研究表明，对改善夜间和日间症状均有效。然而，改善的客观数据尚缺乏。重复多导睡眠图既昂贵又需要替代方法来评估大肌肉运动。在这项小型病例系列研究中，我们介绍了 3 例不安腿睡眠障碍儿童的活动记录仪结果，这些儿童连续采集了 1 周，在静脉铁补充治疗前 1 周和治疗后 8 周。尽管我们的 3 例患者之间的活动记录仪参数并不高度一致，但症状的改善似乎与活动记录仪中的睡眠参数平行。
