Smartphone movement health assessment introduces a new measure of health that helps users analyze and improve their mobility, stability and posture through performance of movements and physical exercises. To verify the accuracy of this measure, the goal is to provide data-driven evidence regarding its accuracy in comparison to gold standard tests for measuring movement health. To address this challenge, the assessment scores will be benchmarked to a set of gold standard tests and sensor metrics for measuring movement health recommended by professional associations such as the American Physical Therapy Association (APTA) or American College of Sport Medicine (ACSM) and found valid in clinical studies , .
