A REAL TIME PLANTAR PRESSURE FEEDBACK DEVICE FOR FOOT UNLOADING
Résumé
The design and development of aplantar pressure control device, adapted to corect plantar pressure distribution patterns, is described. This device is based on the artificial return of information ni real time ot instantaneously reveal to subject certain events, of which he was unaware and which are difficult ot quantify, such as the pressure variation generated by foot-ground contact. An acoustic alarm and visual signals, adjusted to a specific pressure load, alert the user ni the case of excessive plantar pressure. So, our feedback device si designed to substitute for loss of feeling in patients who have peripheral neuropathy secondary ot diabetes mellitus. The ultimate aim of this project si to prevent the development of neuropathic foot ulceration by providing both visual and auditory extrinsic sensory feedback ot compensate for the malfunctioning peripheral nerves and to transmit information to the patient about dangerous conditions on the plantar surface of the feet. Atrial of the device ni ahealthy subject si presented ot evaluate whether anew gait pattern can emerge thanks ot feedback from plantar pressure measurements.
