  • n. The use of the actigraph to record the movements of a sleeping subject, and analyze the subject's sleep patterns


Sorry, no etymologies found.


  • The alternative approach in sleep research is called actigraphy, and it pretty much takes the opposite direction.


  • During the study the participants wore an actigraphy watch sensor which monitored their sleep and wake cycles and kept a daily diary on their sleeping patterns. - Telegraph online, Daily Telegraph and Sunday Telegraph

  • The actigraphy measurements of participants who consumed the cherry juice saw an increase of around 15 minutes to the time spent in bed, 25 minutes in their total sleep time and a 5-6% increase in their ‘sleep efficiency', a global measure of sleep quality. - Telegraph online, Daily Telegraph and Sunday Telegraph

  • Objective sleep was measured by actigraphy, and subjective sleep by the Pittsburgh Sleep Quality Index.


  • The trade off between polysomnography and actigraphy has been well known among sleep researchers for several years.


  • Research has found that, while polysomnography data corresponds more closely to what actually happens during the night, actigraphy is surprisingly accurate, too.


  • Rather than try to measure every last variable, actigraphy looks to measure just one metric - movement - with one sensor (called an accelerometer).


  • Height and weight measurements were also taken, and each participant's sleep/wake cycles were monitored for five days using wrist actigraphy and self-reported sleep logs.

  • The researchers monitored the patients for five days for their sleep/wake cycles using wrist actigraphy and self-reported sleep logs, run overnight polysomnography test for OSA, and measured hemoglobin A1C, which is a clinical marker for glycemic control in type 2 diabetes patients.

  • In the current study, Dr. Maurer, together with Susan Delisle, NP, and the Healthcare Innovation and Technology Lab at Columbia University, found significant discrepancies between self-reported fatigue and actigraphy readings, suggesting that these readings provide complimentary and important information about the link between heart failure, sleep disorders and impairments in health-related quality of life that may be operative through anergia. - latest science and technology news stories
