Abstract
A foot pad device and a method of obtaining weight data from a force sensor in a foot pad worn by a user engaging in a footstep, including placing the force sensor under the ball of the foot of the user and/or the heel of the foot of the user; receiving an entered patient weight value for the user; collecting force data from the force sensor; calculating a weight value based on the collected force data and a scaling and/or offset parameter; comparing the calculated weight value to the entered patient weight value; comparing the calculated weight value to zero; adjusting the scaling and/or offset parameter; and repeating the steps periodically. The method may include comparing the collected force data to a functionality indication range, flagging the force sensor if the collected force data is outside the functionality indication range, and disregarding force data from the flagged force sensor.
