Do patients with primary insomnia differ from good sleepers with respect to the number or duration of awakenings or to the stages from which awakenings occur? To address this question, polysomnography (PSG) records were evaluated in 10 good sleepers (GS) and 10 primary insomnia patients (PI). PSG records were evaluated for occurrence and duration of awakenings and for the stage immediately preceding each awakening. PIs woke more frequently and for longer durations than did GSs. PIs' awakenings tended to occur from Stages 1 or 2; GSs' occurred from epochs scored as movement times. The data from this study represent the first attempt to characterize the stages from which awakenings occur in sleep maintenance insomnia.
原发性失眠患者与睡眠良好者在觉醒次数、觉醒持续时间或觉醒发生的睡眠阶段方面是否存在差异？为了回答这个问题，对10名睡眠良好者（GS）和10名原发性失眠患者（PI）的多导睡眠图（PSG）记录进行了评估。对PSG记录评估了觉醒的发生情况、持续时间以及每次觉醒前的睡眠阶段。原发性失眠患者比睡眠良好者觉醒更频繁，持续时间更长。原发性失眠患者的觉醒往往发生在第1或第2阶段；睡眠良好者的觉醒则发生在记录为运动时间的时段。这项研究的数据代表了首次尝试对睡眠维持性失眠中觉醒发生的睡眠阶段进行特征描述。
