“…Long-term monitoring of sleep requires more practical methods. Use of actigraphy, while a viable alternative, [7][8][9] is limited by the need for costly, specialized equipment and may be considered cumbersome by some patients. A reliable, affordable and user-friendly smartphone-based app that can monitor sleep-wake cycles would be an invaluable addition to the arsenal at the disposal of practitioners of sleep medicine.…”

“…7,9 Several studies have shown that, as with most devices that rely on movement-based algorithms, actigraphy has a high sensitivity but poor specificity in detecting sleep, and as a result its accuracy suffers as sleep efficiency decreases. 8 This raises the question as to whether using the app might represent an unobtrusive, cost-effective alternative to actigraphy with no loss of reliability. However, any further discussion needs to be tempered by the fact that such calculations for actigraphy are based on more traditional 30-or 60-sec epochs.…”

Study Objectives: Several inexpensive, readily available smartphone apps that claim to monitor sleep are popular among patients. However, their accuracy is unknown, which limits their widespread clinical use. We therefore conducted this study to evaluate the validity of parameters reported by one such app, the Sleep Time app (Azumio, Inc., Palo Alto, CA, USA) for iPhones. Methods: Twenty volunteers with no previously diagnosed sleep disorders underwent in-laboratory polysomnography (PSG) while simultaneously using the app. Parameters reported by the app were then compared to those obtained by PSG. In addition, an epoch-by-epoch analysis was performed by dividing the PSG and app graph into 15-min epochs. S martphones are now ubiquitous. As their technological capabilities continue to improve, both consumers and healthcare personnel are constantly fi nding new and innovative uses for smartphone apps in the fi eld of health and medicine.1 Apps have been incorporated into the practice of medical specialties as diverse as diabetology and neurosurgery, and have found a role in activities ranging from interpretation of radiology imaging to smoking cessation counseling. Sleep related concerns are commonplace as well, and given the burgeoning popularity and easy availability of inexpensive apps that purport to monitor multiple physiological parameters, it is not surprising that several apps have been designed to evaluate sleep quality.2 The inexorable permeation of smartphones into the fi eld of sleep medicine has resulted in the development of promising apps that screen for obstructive sleep apnea (OSA) 3,4 and periodic limb movements in sleep (PLMS). S C I E N T I F I C I N V E S T I G AT I O N Sinsomnia, circadian rhythm disorders, and hypersomnolence to have objective data about sleep patterns in order to make diagnoses and treatment recommendations. There are several apps that allow users to report and analyze their sleep quality and duration, 6 but such data are often intrinsically subjective. In-laboratory polysomnography (PSG) is the gold standard for BRIEF SUMMARY Current Knowledge/Study Rationale: There are several preexisting, widely available, inexpensive smartphone apps designed to monitor sleep, but it is unclear whether they have clinical utility. Our goal was to systematically compare the results obtained by using one such app, the Sleep Time app (Azumio, Inc.) to the gold standard, polysomnography (PSG). Study Impact: Our study shows that the absolute parameters and sleep staging reported by the Sleep Time app (Azumio, Inc.) for iPhones correlate poorly with PSG. Further studies comparing app sleep-wake detection to actigraphy may help elucidate its potential clinical utility.

“…For insomniacs actigraphy can provide information about circadian rhythms and sleep patterns (Morgenthaler et al, 2007). Compared with polysomnography, however, actigraphy in insomniacs has had variable results: it has been found to both over and underestimate total sleep time (Vallieres & Morin, 2003;Sivertsen et al, 2006;Sadeh & Acebo, 2002). Another study found that actigraphy was well validated by polysomnography with respect to number of awakenings, wake time after sleep onset, total sleep time, and sleep efficiency (Lichstein et al, 2006).…”

“…Actigraphy -Actisleep Device Polysomnography(PSG) is considered the "gold standard," for sleep study, however, they are expensive, often requiring participants to sleep in a laboratory, limiting their usability [14]. Wrist actigraphy is an acceptable alternative objective method to assess sleep duration [15].…”

A Comparison of Actigraphy and Polysomnography in Older Adults Treated for Chronic Primary Insomnia

Abstract: The present findings suggest 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.
