Abstract
A portable data acquisition system using pressure sensors, built to measure pressures between bony prominences of each foot and the shoe, is described. Data acquisition algorithms for extracting peak pressure, area under the curve, heel strike to pushoff time, and center of pressure are discussed. Sample results of an analysis from 2-h tests on ten subjects are presented, revealing interesting behavior of the pressure changes under the foot and the gait. The results can be used to provide feedback to subjects who have lost sensation from the feet and ankles
