Gait-based biometric system for detecting pathomechanical abnormalities relating to disease pathology

摘要

Systems and methods for diagnosing a user's condition based on his gait. A sensor module with multiple sensors is placed inside a user's shoe and biometric data is gathered from the sensors when the user takes a step or walks. The data is used to generate loops as the various sets of data is plotted against each other. The loops obtained from the data are then compared against stored loops previously obtained. Based on the results of the comparison, the user's condition is diagnosed using predetermined indicators of specific health issues. Using the biometric data, it can be determined whether the user has a specific condition, whether a specific condition is worsening, or whether a specific condition is improving.

1. A method for determining changes in a user's medical condition using a foot-based gait device, said device having a plurality of sensors for gathering gait-based data, the method comprising:
a) selecting two of said plurality of sensors, said plurality of sensors being in said device; b) gathering data from each sensor selected in step a); c) correlating data gathered from said two sensors such that data points gathered at similar instances are matched with one another to result in data pairs; d) determining at least one characteristic loop from said data pairs, each characteristic loop being a loop formed when said data point pairs are plotted; e) retrieving signature characteristic data, said signature characteristic data being derived from data resulting from biometric data previously gathered from said user, said signature characteristic data serving as a baseline set of data to be compared against data gathered from said sensors; f) determining a signature characteristic loop from said signature characteristic data; g) comparing characteristics of said at least one characteristic loop determined in step d) with characteristics of said signature characteristic loop determined in step f) to determine differences data between said characteristics of said at least one characteristic loop from step d) and characteristics of said signature characteristic loop from step f), said differences data including at least one of: loop differences, types of differences between said loops, and an amount of said differences: h) if a comparison of said characteristics compared in step g) produces results not within predetermined limits, determining that a change has occurred in said user's medical condition; i) if a comparison of said characteristics compared in step g) produces results within predetermined limits, determining that a change has not occurred in said user's medical condition.
