Clinical Validation of New Commercial Sleep Monitoring Devices

This study seeks to validate three new commercial sleep monitoring devices: Fitbit, Jawbone
UP, and Microsoft Band by comparison against concurrent polysomnography (PSG), considered the
gold standard assessment for sleep physiology. The investigators emphasize here that the
commercial sleep monitoring devices (Fitbit, Jawbone UP, and Microsoft Band) are used in
addition to PSG and not in place of it. Subjects will be recruited from those patients
attending a regularly scheduled overnight PSG sleep study at the Weill Cornell Medical
College Center for Sleep Medicine. Willing subjects, after providing informed consent, will
be fitted with one of the three aforementioned sleep monitoring devices (randomly assigned)
on the wrist of their non-dominant hand when prepared for the sleep study by a technician.
Subjects willing to wear more than one sleep monitoring device may be fitted with two
different sleep monitoring devices, e.g., a Fitbit and a Jawbone UP or a Fitbit and a
Microsoft Band. Sleep monitoring device(s) will be removed from the subject's wrist in the
morning at the conclusion of the sleep study. Data will be transferred from the sleep
monitoring device(s) for later statistical analysis and comparison with scored polysomnogram.
Device(s) will be cleaned (using antiseptic wipes), reset,recharged, and otherwise prepared
for reuse.
