Introduction

Development of diabetic foot disorders is one of the most serious and costly complications of diabetes mellitus.1 Foot ulcers and amputations are major causes of morbidity and disability in this population. The identification of patients at risk for diabetic foot should be the first step in preventing such complications.2 Diabetic foot clinical examination involves a 10-g Semmes-Weinstein monofilament test, palpation of peripheral arterial pulses, subjective assessment of skin temperature, as well as the observation of structural and dermatological characteristics of the feet. However, this protocol is greatly dependent of observer knowledge and experience. Digital infrared thermal imaging based thermography is able to quantify small temperature asymmetries in order to monitor some physiological conditions. This technique has great portability and poses no risk to …
