Halo branded solutions seattle8/13/2023 Deep learning-based pose estimation methodologies, such as OpenPose 33 and DeepLabCut 34, can accurately extract the pose of a person from videography. Recent advancements in computer vision and artificial intelligence, combined with the ubiquity of high-powered, camera-enabled smartphone devices in society, provide opportunities for innovative digital healthcare solutions for monitoring and improving movement health. However, some of these assessments are not standardized and most require visiting a trained clinician/researcher with dedicated equipment, making movement health screening largely inaccessible for much of the population. These examinations include the Functional Movement Screen (FMS) 3, 14, 15, 16, The Landing Error Scoring System (LESS) 17, active range of motion measurements 18, the sit and reach test 19, reach behind back 14, hop tests 20, 21, functional reach test 22, Sharpened Romberg 23, 24, Star Excursion Balance Test 25, upper extremity Y balance test 26, Closed Kinetic Chain Upper Extremity Stability Test 27, plumb line test 28, Clinical Test of Sensory Interaction in Balance 24, 29, hurdle step test 16, the unilateral hip bridge endurance (UHBE) test 30 and others 31, 32. However, researchers have developed examinations that test different sub-criteria or aspects of movement patterns. ![]() Targeted corrective exercises have been shown to be effective in improving movement health in areas that are lacking, particularly in mobility-impaired or elderly individuals exhibiting the decreased levels of functional mobility that come with age 4, 5, 6, 12, 13.Ĭurrently, there is no universal gold standard measurement for assessing an individual’s movement health. Increased activity and improved movement health can also benefit mental health, acting as a natural treatment for anxiety, depression, and stress 9, 10, 11. Improving movement health by targeting mobility, stability, flexibility, and posture may contribute to reducing injury risk, improving athletic performance, and increasing the physiological capacity to perform normal everyday activities 1, 2, 3, 4, 5, 6, 7, 8. The ability to efficiently and effectively perform these basic actions can be referred to as “movement health”. Nearly all tasks of daily living involve body movements consisting of simple actions such as walking, lifting, bending, twisting, pushing, and pulling. These results support using Halo Movement’s overall score as a valid assessment of movement health. Further, the smartphone assessment is able to differentiate regular healthy individuals from professional movement athletes (e.g., dancers, cheerleaders) and from movement impaired participants, with higher resolution than that of existing functional movement screening tools and thus may be more appropriate than the existing tests for quantifying functional movement in able-bodied individuals. On a diverse cohort of 150 participants of various ages, body types, and ability levels, we find moderate to strong statistically significant correlations between the Halo Movement assessment overall score, metrics from sensor-based 3D motion capture, and scores from a sequence of 13 standardized functional movement tests. ![]() ![]() In this paper, we validate Halo Movement, a movement health assessment which utilizes the front-facing camera of a smartphone and applies computer vision and machine learning algorithms to quantify movement health and its sub-criteria of mobility, stability, and posture through a sequence of five exercises/activities. With digital health and movement monitoring becoming more ubiquitous in society, smartphone applications represent a promising avenue for quantifying, monitoring, and improving the movement health of an individual. The benefits of improved movement health have long been recognized and are wide-ranging from improving athletic performance to helping ease of performing simple tasks, but only recently has this concept been put into practice by clinicians and quantitatively studied by researchers. Movement health is understanding our body’s ability to perform movements during activities of daily living such as lifting, reaching, and bending.
