Infrared thermal imaging of the diabetic foot in Guadeloupe
Study of Infrared Thermography in Diabetic Foot in Guadeloupe (ETPDG)
This will test whether infrared thermal imaging shows different foot temperatures in healthy adults, people with diabetes, and people with diabetic foot ulcers in Guadeloupe.

What this trial studies
This observational project will use non-invasive infrared thermography to measure temperatures at four areas of the plantar surface in three groups: healthy Afro-Caribbean adults, adults with diabetes, and adults with diabetic foot ulcers. Imaging may be combined with 3D surface mapping to precisely localize temperature differences. The primary aim is to compare thermographic patterns across groups to see if diabetic status or ulceration is associated with distinct temperature changes in this tropical population. Results will inform whether thermography reveals visible or subclinical signs that could help detect infection or ulceration risk.
Who should consider this trial
Good fit: Ideal candidates are adult Afro-Caribbean residents of Guadeloupe who can give informed consent, including healthy volunteers and people with type 1 or type 2 diabetes with or without a single foot ulcer.
Not a fit: Patients under 18, those with prior leg fractures or surgery, amputations, bilateral ulcers, neurological disease, pregnancy, active foot mycosis, or who refuse consent are excluded and unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, this could offer a quick, non-invasive way to spot abnormal foot temperatures and help identify infection or ulceration risk earlier to reduce complications and amputations.
How similar studies have performed: Some small prior studies and case series have shown thermography can detect temperature changes before ulceration or infection, but evidence is limited and current international guidelines do not recommend routine use.
