What is it about?
Researchers developed X-QST, a wireless system that tests how people detect cold, warmth and heat pain, including paradoxical heat sensations. Tested in 15 healthy adults, it was integrated into a digital platform for screening diabetes complications.

Why is it important?
Small nerve fibers that sense temperature can be affected early in diabetic peripheral neuropathy. A wireless system measuring cold, warmth and heat-pain responses could make thermal sensory testing easier to integrate into broader diabetes screening.
Perspectives
X-QST showed technical feasibility in healthy adults, but its ability to detect diabetic neuropathy was not tested. Studies in people with diabetes, with and without neuropathy, are needed to establish diagnostic accuracy, reference values and clinical usefulness.
