An Australian study in the March issue of the Journal of Clinical Sleep Medicine compared two commercial sleep devices – an accelerometer worn as a wristband (UP by Jawbone) and a smartphone application (MotionX 24/7) – against polysomnography (PSG) and actigraphy (Actiwatch2) in a clinical pediatric sample.

Results suggest that, when compared to PSG, UP was analogous to Actiwatch2 and may have some clinical utility in children with sleep-disordered breathing. According to the authors, MotionX 24/7 did not accurately reflect sleep or wake and should be used with caution.
