A measure used to assess sleep quality, usually determined by means of polysomnography. A parameter such as wake after sleep onset (WASO) is often used to describe sleep continuity. 

Since the publication of the Standardised Sleep Manual by Rechtshaffen and Kales (Eds) in 1968, human sleep has been described using a classification system based on a combination of EEG, EMG and EOG features. The acquisition and use of such data is known as polysomnography. Note, that when including the state of WAKE in the classification, these are most accurately described as arousal states in place of sleep stages.

Nocturnal polysomnography Visual and electrophysiologic assessment of human sleep minimally composed of electroencephalogram, electrooculogram, and electromyogram that allows determination of sleep stage, breathing events, and muscle movements. 

Thanks to the technique of polysomnography, many of the mysteries of sleep are now becoming better understood. First, sleep is divided into two main phases rapid... 

Infants, school-age children, and adolescents have been studied in the laboratory, hospital nurseries, schools, institutions, and their homes with polysomnography, time-lapse video monitors, activity monitors, diaries, and self- and parent-report instruments. Children both with and without sleep disorders have been evaluated with these various assessment procedures, and researchers have used a wide range of study designs to investigate the impact of inadequate sleep. For example, in laboratory studies children and adolescents have been assessed on their usual (often arguably inadequate) schedules as well as on study-defined optimized and restricted... 

Polysomnography has been used in both laboratory and home-based studies of children and adolescents to obtain measures of sleep and sleep-related events (10,25-31), and also measures of daytime sleepiness from the Multiple Sleep Latency Test (MSLT) procedure (11). Because polysomnography is so expensive, most of these studies have obtained only one or a few nights of study for cross-sectional samples of children and adolescents at different ages or devel-...

In Germany, Cassel et al. (30) at the same time showed that apneic patients diagnosed by clinical interview and polysomnography were frequently involved in sleep-related accidents (30). 

As with other aspects of sleep studies, polysomnography (PSG) can provide an exact quantification of rebound in terms of both sleep stages and more sophisticated analyses [7], However, it cannot measure the clinical implications of the rebound, for example, does the patient feel compelled to resume medication Nor does it assess withdrawal reactions, except in as much as they often subsume rebound sleep phenomena.
