During the last decade actigraphy (activity-based monitoring) has become an essential tool in sleep research and sleep medicine. The validity, reliability and limitations of actigraphy for documenting sleep-wake patterns have been addressed. Normative data on sleep-wake patterns across development have been collected. Multiple studies have documented the adequacy of actigraphy to distinguish between clinical groups and to identify certain sleep-wake disorders. Actigraphy has also been shown to…

Comparison of actigraphy with polysomnography and sleep logs in depressed insomniacs

It is demonstrated that, while bias was limited between PSG and the other two measurement types, there were somewhat broad 95% limits of agreement for all sleep variables with both sleep diaries and actigraphy.

Actigraphy, does it add value?

It is not sufficient as a stand-alone device to diagnose sleep-disordered breathing and any disorder which cause motion artefact limits its utility, so controlling artifacts by using sleep logs and diaries will improve the efficacy.

Ambulatory monitoring of sleep disorders.

Actigraphy cannot stand alone as a diagnostic tool for all clinical groups, particularly so with those diagnosed with sleep disorders with significant motility or long catatonic periods of wakefulness during sleep.

Actigraphy for measurement of sleep and sleep-wake rhythms in relation to surgery.

Actigraphy can be used to measure sleep and sleep-wake rhythms in patients undergoing surgery and could determine a differential effect of surgery based on the patient's age.

Wake detection capacity of actigraphy during sleep.

The very low ability of actigraphy to detect wakefulness casts doubt on its validity to measure sleep quality in clinical populations with fragmented sleep or in situations where the sleep-wake cycle is challenged, such as jet lag and shift work.

Actigraphy for the assessment of sleep measures in Parkinson's disease.

The results suggest that actigraphy may be useful for measurement of mean TST, SE, and WASO values in groups of patients with mild to moderate Parkinson's disease, however, there is a significant degree of variability in accuracy among individual patients.

A comparison of actigraphy and polysomnography in older adults treated for chronic primary insomnia.

It is suggested that the clinical utility of actigraphy is still suboptimal in older adults treated for chronic primary insomnia and should, hence, be used in this clinical setting with the concurrent use of supplementary assessment methods.



The role of actigraphy in the evaluation of sleep disorders.

The data suggest that actigraphy, despite its limitations, may be a useful, cost-effective method for assessing specific sleep disorders, such as insomnia and schedule disorders, and for monitoring their treatment process.

Wrist actigraphic measures of sleep in space.

Actigraphy worked well in space both as a way of detecting bedtimes and waketimes, and as an indicant of sleep restlessness.

These clinical guidelines, which have been reviewed and approved by the Board of Directors of the American Sleep Disorders Association, provide recommendations for the practice of sleep medicine in

Use of wrist activity for monitoring sleep/wake in demented nursing-home patients.

It is concluded that theactigraphy is the most feasible technique for studying sleep and wake activity in demented nursing-home patients by testing the reliability of a wrist-activity monitor, the Actillume, against traditional sleep measurements and against observations of nursing- home patients.

Wrist actigraphy in insomnia.

Actigraphy is recommended as an additional tool in the clinical evaluation of insomnia, but it is believed that in complex cases it should be combined with 1 PSG night in the sleep disorders center.

Use of the wrist actigraph to study insomnia in older adults.

The actigraph was sufficiently sensitive to detect the effect of the sleep restriction therapy used on several sleep measures, suggesting that the sleep log, although not an accurate measure of sleep, may be useful as a measure of elderly insomniacs' subjective perception of sleep.

Activity-based sleep-wake identification: an empirical test of methodological issues.

Statistical manipulation of activity levels before applying the scoring algorithm indicated that this algorithm is quite robust toward moderate changes in activity level, and was consistently higher than for wake scoring.

Determination of sleep and wakefulness with the actigraph data analysis software (ADAS).

A study aimed at the development of a new scoring software that can accurately identify sleep and wakefulness using total sleep time as an index of comparison.
