Foot temperature monitoring has emerged as a promising method to predict the onset of diabetic foot ulcers (DFUs) before visible signs appear. The principle is based on detecting subtle changes in temperature that reflect localised inflammation, which often precedes tissue breakdown.
Research from the Netherlands and the USA shows that daily foot temperature checks using handheld thermometers or wearable sensors can significantly reduce ulcer incidence in high-risk diabetic patients. These tools can identify “hot spots” which signal the need for offloading or clinical intervention.
In South Africa, thermographic tools are not widely used in podiatric practice due to equipment cost and availability. However, awareness of these developments is important. Podiatrists can implement manual temperature checks as a cost-effective alternative and educate high-risk patients on home monitoring routines.
Adoption of foot temperature monitoring, even in basic forms, can greatly enhance early detection and prevention of ulcers, especially in patients with a history of previous ulceration or peripheral neuropathy.
While advanced thermographic devices may be out of reach for many South African practices, integrating basic foot temperature checks could become a powerful tool in diabetic ulcer prevention.
