The position of the centres of the sensors of the parotec pressure measurement insoles system related to the anatomy centres of the metatarsal heads by means of radiological records

This study pretend to establish the anthropometric relationship between the position of osseous prominences (metatarsal heads, proximal and distal phalanxes bones) of the feet in a group of diabetic patients, and the position of the sensors of the electronic German Parotec insoles system, located in the same areas to register the plantar pressure distribution in standing position by using RXs. The aims of this study were: a) to establish the position of the centres of the sensors of the Parotec insoles related to the centres of the metatarsal heads and distal ends of the proximal phalanges and the proximal ends of the distal phalanges phalanxes of the feet, in a group of 12 diabetic subjects wearing different type of shoes, by means of radiological records, in order to answer the following questions: (1) Can the Parotec insoles designed for registering plantar pressure distribution on diabetic German people be used for measuring pressure distribution on a group of 12 diabetic type 1 and type 2 Colombian people evaluated in this study? (2) Are those bones landing according to the Parotec sensor position? (3)Which would be the proper distribution of the Parotec sensors for this group of subjects? b) To establish if the use of different types of footwear (sports, conventional and orthopaedic footwear) with the Parotec electronic insoles can influence the position of the osseous prominences in relation to the position of the sensors that register the pressure in these areas. This project was developed with the collaboration of the Electronics Department and the Orthopaedics and Trauma Department of the Javeriana University and the San Ignacio Teaching Hospital in Bogotá, under the supervision and cooperation of the Bioengineering Unit of Strathclyde University. COLCIENCIAS, a government sponsored research institution of Colombia; and the clinical orthopaedic centre Ortesica specialized in diabetic foot care supported the interdisciplinary team from the Javeriana's Bioengineering Research Group.
