Budget camera could spot diabetic foot trouble early
NCT ID NCT07463456
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 2 times
Summary
This study checks if a cheap thermal camera (about 200 euros) works as well as a professional one for spotting early signs of foot problems in people with diabetes. 130 adults with diabetes will have both cameras take pictures of the bottom of their feet. The goal is to see if the low-cost camera can reliably find temperature differences that might signal a problem.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 years or older. * Confirmed diagnosis of type 1 or type 2 diabetes mellitus. * Preserved plantar skin integrity at the time of the test. * Voluntary signature of the informed consent after receiving detailed information about the study. Exclusion Criteria: * Active ulcers or open wounds in the plantar area, since exudation alters thermal emissivity. * Acute skin infection or extensive mycosis of the foot. * Previous partial amputation of the forefoot or midfoot that alters the anatomy of the regions of interest. * Severe peripheral arterial disease (Fontaine grade IV, critical ischemia) compromising tissue viability. * Physical or cognitive inability to remain in the semi-Fowler position (backrest 30 to 45 degrees) during the 15 minutes of the acclimatization protocol. * Intense physical activity or hydrotherapy within the 2 hours before the appointment, and caffeine intake or tobacco use within the same period, because of their vasoconstrictor effects. * Acute febrile state, body or tympanic temperature above 37.5 degrees Celsius at the time of the test. * Application of creams, moisturizing lotions, topical ointments or talcum powder to the plantar area within the 4 hours before the examination, because of the alteration of infrared emissivity and the evaporative cooling effect.
