Plantar load comprises of normal pressure and shear stress, however, there are currently no in-shoe devices capable of measuring both components. The STrain Analysis and Mapping of the Plantar Surface (STAMPS) system, developed at the University of Leeds, utilises Digital Image Correlation (DIC) to measure the strain captured by a plastically deformable insole, as a method to understand plantar load during gait. A 2D DIC software was used to capture cumulative plantar strain and displacement pointwise data, however this method was limited to the analysis of planar surfaces. To address this, 3D instrumentation and DIC methods have been developed and implemented into the STAMPS3D system, used as a tool to capture data that is representative of the non-planar nature of plantar surfaces of the foot. A case-study is used to demonstrate how STAMPS3D can measure multi-dimensional strain, bringing potential to improve clinical screening of DFU risk.<\/jats:p>","DOI":"10.1177\/09544119251330738","type":"journal-article","created":{"date-parts":[[2025,4,12]],"date-time":"2025-04-12T17:12:43Z","timestamp":1744477963000},"page":"472-484","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Development and evaluation of a novel 3D in-shoe plantar strain measurement system: STAMPS3D"],"prefix":"10.1177","volume":"239","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0641-9350","authenticated-orcid":false,"given":"Francesca","family":"Sairally","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, University of Leeds, Leeds, West Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rory P","family":"Turnbull","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, University of Leeds, Leeds, West Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heidi J","family":"Siddle","sequence":"additional","affiliation":[{"name":"Leeds Institute of Rheumatic and Musculoskeletal Medicine, University of Leeds, Leeds, West Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A","family":"Russell","sequence":"additional","affiliation":[{"name":"Leeds Vascular Institute, Leeds Teaching Hospitals NHS Trust, Leeds, West Yorkshire, UK"},{"name":"Leeds Institute of Clinical Trials Research, University of Leeds, Leeds, West Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claire","family":"Brockett","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Sheffield, Sheffield, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2867-0420","authenticated-orcid":false,"given":"Peter R","family":"Culmer","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, University of Leeds, Leeds, West Yorkshire, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,4,12]]},"reference":[{"key":"e_1_3_2_2_2","unstructured":"International Diabetes Federation.
