Plantar Load Analysis of Neuropathic and Neuroischaemic Diabetes-Related Foot Ulceration

This single-centre observational case-control study investigates how peripheral arterial disease influences plantar load in people with diabetes who have recently healed a plantar foot ulcer. Using in-shoe pressure mapping (Pedar™) and 3D digital image correlation of a plasticine deformable insole (STAMPS system), we will quantify vertical pressure and strain magnitude. Weight-bearing ultrasound will assess plantar fat-pad thickness as a potential corollary for forefoot peak pressure and shear. All procedures are non-invasive and completed in a single \~90-minute visit at Leeds Teaching Hospitals NHS Trust.
