In a collaborative effort between Labfront and Garmin, an actigraphy-based sleep analysis report has been developed for Garmins consumer-grade wearable devices, accessible via the Labfront application. Comparative analyses against established medical-grade actigraphic devices, namely Actiwatch-2 and Motionlogger, demonstrate notable concordance in key performance indicators. Specifically, the Garmin device yielded a sensitivity of over 95% for sleep detection, a specificity of over 80% for wake detection, and an overall accuracy exceeding 95%. The study introduces a transparent methodology for deriving sleep metrics from acceleration data, thereby addressing a current gap in the literature regarding consumer-grade actigraphy solutions. Additionally, the system allows for individual customization of sleep/wake detection parameters, offering adaptability to specific user conditions. These findings suggest that consumer-grade wearable devices may serve as viable alternatives to medical-grade actigraphs for sleep analysis, without sacrificing analytical rigor.
