New technologies and research aim to prevent diabetic foot ulcer complications

Researchers are exploring diverse technological and biological strategies to combat diabetic foot ulcers (DFUs) and chronic limb-threatening ischemia (CLTI), conditions that pose high risks of amputation and death.

A review published in Burns & Trauma examines how neuromodulatory, humoral, and mechanotransductive interventions might preserve limbs by influencing biological processes far from the initial application site. One method discussed is high-frequency spinal cord stimulation (SCS) at 10 kHz, which aims to alter neural signaling and sympathetic activity to assist in managing painful diabetic neuropathy.

In a separate development, a new AI-powered tool called THERMUL is being tested to improve early intervention. Developed through a partnership involving RMIT University, the University of Melbourne, and Bolton Clarke, the smartphone-based tool uses thermal imaging and artificial intelligence to analyze heat patterns in foot wounds. Clinical testing at Austin Health and St Vincent’s Hospital Melbourne demonstrated the tool's ability to predict whether an ulcer will heal within a 12-week period, potentially allowing clinicians to intervene earlier and prevent serious complications, particularly for those in remote communities.
