BioimPEDance of Diabetic Foot Ulcers

Characterisation by Electric Impedance Measurements of the Different Wound Healing Phases of Diabetic Foot Ulcers

The BIPPED study seeks to determine whether wound healing, in particular diabetic foot ulcers, can be monitored using electrical bioimpedance analysis (BIA). BIA measures the resistance of biological tissue to the passage of a very small electric current applied with electrodes. Different types of tissue, due to cell structure, hydration and vascularization, have specific electrical characteristics. The BIPPED study aims to provide experimental data for the development of a BIA sensor for monitoring of wound healing in chronic wounds.

Inclusion Criteria:

• diabetic patient (Type 1 or 2) with diabetic foot ulcer or lower limb ulcer
• written informed consent signed
• insured by the French national health insurance scheme

Exclusion Criteria:

• wound in the similar position on the other limb
• people under legal protection
• unilateral limb oedema
• contra-indication to impedancemetry : pregnancy, patient with a pacemaker, neurostimulator or any other implanted electrical device, metallic prostheses
• patients participating to other protocols involving foot ulcers measurement, if it interfers with the current protocol.
