Some of these include this recent evaluation of two clinical-grade actiwatches – the GT3X+ and Actiwatch Spectrum as well as an evaluations of the commercial Jawbone UP device with adults and adolescents. There are a growing number of studies that attempt to independently validate their accuracy against multi-parametric polysomnography (PSG) measures which include EEG, EOG (eye movements), EMG (muscle activity) and ECG (heart rhythm). Wearables such as Fitbit, Jawbone (which is now going out of business) and Polar generally sense movement and use these movement patterns (actigraphs) to predict night wakings and stages of sleep.
PHILIPS SMARTSLEEP WEARABLE SLEEP IMPROVEMENT SYSTEM SOFTWARE
Improved algorithms, the launch of a Sleep Technology Council by the National Sleep Foundation and an increased availability of high resolution raw data from software platforms such as Fitbit’s Fitabase all help to connect the dots between wearable manufacturers and clinical scientists. And although the majority of these technologies claim that they are not intended for scientific or medical purposes, the gap between them and clinical-grade devices, is rapidly closing.
The ability to track an array of physiological, sleep and activity metrics 24 hours a day, 356 days a year, offers the opportunity to combat bad habits, improve health and obtain a level of physical enlightenment beyond our own self report and guesstimation.įrom a research perspective these relatively low-cost technologies offer an unprecedented window into the health and sleep behavior of millions of individuals. Wearable technology is fast becoming the new norm. How accurate are they and what can they really tell you? Most measure sleep based on movement, although new EEG based sleep headbands are hitting the market. Wearable sleep trackers have become ubiquitous.
