revealed are the algorithms for a purely objective , reliable and reproducible mobility assessment tool system with computerized fuzzy - logic algorithms that administer complex bio - mechanical assessments of a subject &# 39 ; s static and dynamic balance and locomotion during performing 8 movements , by the administration of those algorithms to the skeleton nodal data stream representation of the movements derived from the 3 - d video data stream observations or recordings of the subject performing the movements according to established kinesiology mobility standards . each specific movement is measured as a function of 13 specific features &# 39 ; values that are determined by that function &# 39 ; s algorithms for which there are adjustable parameters that allow calibrating the range limits of each feature &# 39 ; s value of the assessments for select populations including gender , age , athleticism , and injury or disease subgroups .
