[Polysomnographic structure of subjective "awake" and "asleep" nocturnal segments].
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.
