Our research at the Centre for Biomechanics and Rehabilitation Technologies (CBRT) have been aimed at understanding and addressing the significant issue of diabetic foot ulcers, which are a leading cause of lower-limb amputations worldwide. Annually, these ulcers result in approximately one million amputations globally. Foot ulcers affect between 19% and 34% of individuals with diabetes, leading to a notable increase in the risk of mortality within five years to 70%. This risk is 2.5 times higher compared to non-ulcerous diabetes patients. Our work focuses on developing innovative approaches to tackle these pressing challenges. The factors that contribute to the vulnerability of feet to ulceration in individuals with diabetes, including both tissue and biomechanical characteristics, remain an area of ongoing study.
We have developed new biomechanical assessment protocols to identify patients at risk of diabetic foot ulcers. These evidence-based methods allow clinicians to evaluate foot function and customize early interventions. We have also created novel technologies for designing and fabricating biomechanically informed insoles for diabetes patients. These technologies enable personalised insoles to be prescribed based on a scientific understanding of each patient’s foot biomechanics, plantar pressures, and risk factors.
By advancing assessment techniques and promoting mechanically optimised insoles, the CBRT’s research has produced meaningful outcomes for clinics and patients. Biomechanics-focused preventative strategies and treatments show promise to reduce the incidence of devastating diabetic foot complications. Ongoing research in this application of biomechanics aims to further improve clinical practice and patient health.
