背景：睡眠中周期性肢体运动（PLMS）的夜间变异性状况尚未明确。考虑到这一点，我们研究了在日本疑似不宁腿综合征（RLS）或周期性肢体运动障碍（PLMD）患者中使用PAM-RL装置的活动记录仪测量PLMS的有效性，以及受试者之间PLMS的夜间变异性。方法41例受试者（平均年龄52.1±16.1岁）同时进行多导睡眠图（PSG）和PAM-RL测量。此后，受试者在家中连续四个晚上使用PAM-RL。结果PSG的PLMS指数（PLMSI-PSG）与PAM-RL的PLM指数（PLMI-PAM）的相关系数为0.781 （P< 0.001）。当PSG的PLMSI截止值设定为每小时15次时，预测该PLMSI水平的截止值为每小时16.0次。当条件被设置为平均类间相关系数达到大于或等于0.9的水平时，对于PLMI小于每小时15次的受试者，重复测量所需的夜数是26晚，对于那些在PAM-RL上PLMI大于或等于每小时15次的受试者，需要的夜数是3晚。结论spam - rl对日本受试者的PLMS也有一定的评价价值。可能需要连续三晚或更长时间记录PAM-RL，以确保疑似病理上频繁发生PLMS的患者的筛查可靠性。
BackgroundThe status of night-to-night variability for periodic limb movements in sleep (PLMS) has not been clarified. With this in mind, we investigated the validity of PLMS measurement by actigraphy with the PAM-RL device in Japanese patients with suspected restless legs syndrome (RLS) or periodic limb movement disorder (PLMD) and the night-to-night variability of PLMS among the subjects.MethodsForty-one subjects (mean age, 52.1 ± 16.1 years) underwent polysomnography (PSG) and PAM-RL measurement simultaneously. Thereafter, subjects used the PAM-RL at home on four more consecutive nights.ResultsThe correlation between PLMS index on PSG (PLMSI-PSG) and PLM index on PAM-RL (PLMI-PAM) was 0.781 (P< .001). When the PLMSI cutoff value on PSG was set at 15 episodes per hour, the cutoff value for predicting this PLMSI level was 16.0 episodes per hour. When the condition was set to the level in which the mean interclass correlation coefficient reached ⩾0.9, the number of required nights for repeated measurements was 26 nights for subjects with PLMI of <15 episodes per hour and three nights for those with PLMI ⩾15 episodes per hour on PAM-RL.ConclusionsPAM-RL is thought to be valuable for assessing PLMS even in Japanese subjects. Recording of PAM-RL for three or more consecutive nights may be required to ensure the screening reliability of a patient with suspected pathologically frequent PLMS.
