Sleep pattern detection using raw tri-axial wrist and hip actigraphy in the Raine Study

  • Published on Jun 21, 2017

Sleep disorders occur in around 20% of the population and are associated with a multitude of serious health implications. Whilst polysomnography is considered the 'gold standard' in assessing sleep patterns, it is intrusive and costly hence actigraphy is increasingly being considered as a viable alternative. Current actigraphic sleep pattern detection algorithms ...


Automated sleep scoring algorithms for activity monitors – a comparison to polysomnography in the Raine Study.

  • Published on Jun 21, 2017

Introduction: Wrist-activity monitors are widely used to assess sleep and activity. Accurate measurement of time at 'lights out' (LO) is essential for calculation of several activity-derived measures including sleep latency (SL), sleep duration (SD), wake after sleep onset (WASO) and sleep efficiency (SE). To determine LO some devices use subjective ...


Assessing sleep using hip and wrist actigraphy

  • Published on Jan. 19, 2015

Abstract: Wrist actigraphy is commonly used to measure sleep, and hip actigraphy is commonly used to measure activity. It is unclear whether hip-based actigraphy can be used to measure sleep. This study assessed the validity of wrist actigraphy and hip actigraphy compared to polysomnography (PSG) for the measurement of sleep. 108 ...
