Patent ID: 7455620

Claim:
A method for interpreting data representing forces and torques exerted by a right and left foot on a first and second plate treadmill to determine forces and torques exerted on the right and left foot, over a specified period of time, comprising: (a) receiving a plurality of signals from the first and second plates in Voltages; (b) converting said data from Voltages to forces and torques with calibration values; (c) analyzing the plurality of signals from the first and second plates to determine an occurrence of heel-strikes on the plates and toe-off events from the plates; (d) filtering said data at a first frequency appropriate for determining frame numbers; (e) filtering said data at a second frequency wherein said second frequency is higher than said first frequency; (f) for each one of said plurality of signals, determining frame numbers corresponding to a stride of an individual wherein each frame number includes a beginning point and an ending point; (g) extracting data for a first side and a second side from each of the first and second plates to obtain a first side data total and a second side data total; and (h) determining which one of the right and left foot corresponds to said first side data and which one corresponds to said second side data.
