Abstract
According to some exemplary embodiments, a method or system can involve associating a plurality of biokinetographic comparison results with a first specific dysfunction from a group of specific dysfunctions, each of the biokinetographic comparison results obtained from a comparison of a biokinetographic value to a standard for a corresponding biokinetographic variable.
Claims23
A method, comprising:
- automatically associating a plurality of biokinetographic comparison results for a unique patient with a first specific dysfunction comprising orthopedic injury;
- obtaining each of the biokinetographic comparison results from an automatic comparison of a biokinetographic value to a standard for a corresponding biokinetographic variable that is linked to one or more specific components of a gait cycle, said one or more specific components selected from a group consisting of a left heel strike, a right heel strike, a toe strike, a right toe lift-off, and a left toe lift-off;
- determining each biokinetographic value automatically from a biokinetographic data set comprising a plurality of scalar sums of acceleration values in each of three orthogonal directions, each scalar sum corresponding to a particular point in time, and
- identifying a cause of the unique patient's condition as an orthopedic injury when the biokinetographic value for the unique patient is asymmetrical cadence with a difference between a first and second double stance time of the unique patient of greater than 25 milliseconds.

A method, comprising:
- automatically:
- obtaining biokinetographic data for a unique patient;
- analyzing said biokinetographic data;
- and
- identifying in said biokinetographic data a first specific biokinetographic pattern for a biokinetographic variable that is linked to specific components of a gait cycle, said specific components including a heel strike, a toe strike, and a toe lift-off;
- automatically associating the first specific biokinetographic pattern with a first specific dysfunction comprising orthopedic injury when the first biokinetographic pattern for the unique patient is asymmetrical cadence with a difference between a first and second double stance time of greater than 25 milliseconds;
- and
- identifying a cause of the unique patient's condition as an orthopedic injury based on the association of the first biokinetographic pattern with a first specific dysfunction comprising orthopedic injury.
