Sleep Measurement Study
Given the importance of sleep behaviour to health, the importance of accurately monitoring sleep duration and quality is becoming more evident. Therefore, validation of a sleep algorithm that can be applied to different accelerometer brands against Polysomnography (PSG) warrants investigation.
PSG is considered the gold standard for sleep assessment. Nevertheless, PSG is impractical, expensive and labour‐intensive which limit its use in large or free-living studies.
Previous studies that validated sleep outcomes from different brands of accelerometers against PSG have reported conflicting results which could be due to the use of different sleep algorithms and accelerometer placement (dominant vs. non-dominant wrist vs. hip).
Therefore, we aim to validate automated sleep algorithms for research grade accelerometers against polysomnography (PSG) in a clinical and healthy adult population.
