Hot Feet?

You’ve heard of hot flashes, well, now there’s something new-hot spots. Located on the soles of your foot, these toasty patches are early indicators of inflammation and tissue damage produced by repetitive stresses.

Researchers from the University of Liverpool and the Diabetes Centre examined 50 patients with diabetes and peripheral neuropathy found that tissue inflammation resulted in higher temperatures, especially under the toes and heels.

Their goal was to help prevent neuropathic foot ulceration, a major cause of limb deterioration, by finding a cheaper and more widely available way of measuring those high pressure points.

Doctors used to use optical pedobarography to measure possible tense areas: unfortunately this equipment is bulky, requires sophisticated analysis, and is not often available. Using Liquid-crystal Contact Thermography (LCT), medical practitioners can now detect an elevated temperature in the feet through a simple, non-invasive method.

LCT, a high-resolution technique particularly useful in showing anatomical variations in skin temperature, provides another option in the prevention of neuropathic foot ulceration.
