What this trial studies

This study aims to assist individuals with diabetic foot ulcers by evaluating the effectiveness of three different types of diabetic boots in promoting adherence to treatment. Participants will be divided into three groups: one will wear a non-removable boot, another will wear a removable boot with counseling on adherence, and the third will use a 'smart' boot that provides real-time feedback through a smartwatch and smartphone. The goal is to determine which boot type encourages better compliance with wearing the boot as prescribed, ultimately aiding in the healing process of foot ulcers.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 or older with diabetic foot ulcers requiring offloading.

Not a fit: Patients with wounds present for more than one year or those with ulcers not caused by diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the risk of amputation for patients with diabetic foot ulcers by improving adherence to offloading treatment.

How similar studies have performed: While there have been studies on diabetic foot ulcer treatments, the use of smart technology for adherence monitoring in this context is relatively novel.
