8 patients being diagnosed as having periodic limb movements in sleep and 14 patients with the diagnosis of psychophysiological insomnia (PI) were studied. They indicated their subjective time of sleep onset, final awakening and wake episodes during the night in a time scale. This subjective data was compared to the polysomnographic data and between the 2 patient groups. There were no significant differences--concerning the polysomnographic structure--between sections indicated as "wake" or "sleep" or between the 2 groups. Patients with PI had less frequent awakenings but of longer duration, which can be seen as a reason for the negative subjective judgement of the night quality.
对8名被诊断为睡眠中周期性肢体运动的患者和14名被诊断为心理生理性失眠（PI）的患者进行了研究。他们在一个时间尺度上指出了自己主观的入睡时间、最终醒来时间以及夜间的清醒时段。将这些主观数据与多导睡眠图数据进行了比较，并在两组患者之间进行了比较。在多导睡眠图结构方面，被标记为“清醒”或“睡眠”的时段之间或两组之间没有显著差异。PI患者的觉醒频率较低，但持续时间较长，这可被视为对夜间睡眠质量主观评价负面的一个原因。
