Computer Assisted Optical Podoscope for Orthostatic Measurements (original) (raw)

Abstract

Extensive static and dynamic foot problems in modern society are a direct consequence of the lifestyle of the individual. Continuous use of transportation, prolonged periods of physical inactivity and obesity modify the normal structure of the foot in time leading to traumatic disorders. Correctly assessing the plantar pressure and identifying potential problems due to the unbalance of the foot structure are key factors in preventing and treating of conditions such as flat feet, high arches, bunions, hammertoes, plantar fasciitis etc. The research leading to this paper addresses these issues and a low cost computer aided optical podoscope is presented. With the use of modern computational systems, patient information can be analyzed, stored and compared and visual pressure points can be linked to accurate measurements when body mass and touch areas are known. By combining different illumination techniques the effects of the environment lighting are diminished and the images of the foot interaction with the sensitive surface increase in resolution. Moreover, the pressure information can be separated or connected to the rest of the foot allowing for better visual identification of the static and dynamic foot problems.
