Physical Activity Monitoring for Research

Physical activity is challenging to conceptualize and quantify. A common indicator used in many disease studies and functional outcomes is physical activity (PA). PA questionnaires have been used for decades as a way to estimate several factors that enables or obstructs PA in everyday life. However, PA questionnaires are subject to reporting bias and inconsistencies.

The MOX Research system provides researchers with unprecedented opportunities to measure physical activity and movement, as well as circadian patterns and trends. Specifically developed for objective research studies suited for different study designs, the unobtrusive waterproof sensor enables 24-7 data collection, providing valuable insights into real-world physical activity levels. Raw data and algorithm output is instantly available, with activity classification that is validated by leading research facilities in Europe.
