1. A method of producing a protocol comprising: (a) accepting a time-series of values representative of parameters of a plurality of body locations on a plurality of individuals while those individuals perform a plurality of motion tasks; (b) analyzing those values with a data mining computer program running on a computer system to effectively assign at least a portion of the plurality of individuals into one of at least two groups based upon that analyzing of the time-series values, each group being composed of individuals having a common physical attribute; (c) identifying one or more subsets of the parameters, and of the associated body locations, and of the associated motion tasks, respectively, that collectively possess effective statistical power to assign an individual to their proper group; further; (d) identifying rules, that when applied to the subset of the parameters, and of the associated body locations, and of the associated motion tasks properly assigns an individual to their proper group; (e) enumerating the subsets and rules for application to an unknown subject for effectively assigning the unknown subject to their proper group.
