Gait analysis system and methods
First Claim
1. A method for analyzing the gait of an individual wearing a left shoe and a right shoe, the method including the steps of:
- (a) acquiring data from a first array comprising a plurality of pressure sensors and shear stress sensors configured for placement in a left shoe and from a second array comprising a plurality of pressure sensors and shear stress sensors configured for placement in a right shoe, the acquired data being separated into at least two separate gait phases for each array;
(b) comparing at least a portion of the acquired data to a baseline condition for each gait phase; and
(c) categorizing the sensors in each array, or a group of sensors in each array, into one of at least two uniformity categories for each gait phase based on the comparison of the acquired data to the baseline condition.

Abstract
Systems and methods for analyzing the gait of an individual are disclosed. The disclosed systems and methods can be configured to acquire data from a first array and a second array of sensors that are configured to be placed in a left and/or right shoe, respectively. The acquired data can be collected or separated into at least two separate gait phases for each array, compared to a baseline condition for each gait phase and categorized into one of at least two uniformity categories for each gait phase. Examples of collected and/or calculated data include pressure values, shear stress values and torque values. The analysis can be focused on both feet of a person, or focused on one foot. A graphical output showing at least one entire gait cycle based on the uniformity categories can then be generated.
