Material Selection for Diabetic Custom Insoles

Introduction Diabetic foot ulceration is one of the most significant causes infection and amputation in neuropathic patients. Most often, plantar surface affected. Offloading by custom-molded insoles considered a crucial step prevention diabetic ulcers, although beneficial choice materials not well documented. This review focuses on identifying suitable material compositions for offloading foot. Materials Methods A systematic was performed with aid clinical librarian September 9, 2020. The according to Preferred Reporting Items Systematic Reviews Meta-analysis (PRISMA) guidelines. Studies were included based following eligibility criteria: interventions terms selection/properties outcomes reported as either pressure reduction and/or ulcer prevention. Bench studies also included. At each level selection, records reviewed two independent reviewers. Clinical appraised using ROBINS-1 tool. Results Through database search, 1131 identified an additional eight through references other sources. After removal duplicates, 927 screened, which resulted 74 full-text assessed eligibility. Thirty-seven qualitative synthesis. Twelve examined properties bench testing. Five finite element analysis. Nineteen parameters identified. Six supported use moderately deformable insole production. showed better performance combination under sustained loading. concluded that increasing thickness increased capabilities. Conclusions diversity study designs date precludes ability recommend type over other. Still some general considerations can be made. For solo-material insoles, are preferable, balancing need durability. Increasing may increase longevity insoles. Combining different seems enhance both capability durability Relevance When single-material design, preferable. enhances
