Guided Plantar Footprint Assessment and Parametric Orthotic Insole Specification: Software Description and Computational Verification

Abstract

Amidst the evolution of digital tools in the fields of rehabilitation medicine and orthopedics, the "Console App: Guided Plantar Footprint Assessment & Parametric Orthotic Insole Specification" emerges as a specialized technical aid. It is designed to support professionals in assessing plantar footprints and determining preliminary specifications for parametric orthotic insoles.The application’s scientific and computational framework is grounded in 14 authoritative research papers published in peer-reviewed journals that meet high levels of evidence standards; these papers are internationally recognized references for assessing the medial longitudinal arch and designing orthotic devices.The application integrates educational and computational functions into a single, user-friendly interface. It features 12 validated qualitative assessments based on plantar footprints, supported by precise illustrations explaining each specific indicator. These assessments include globally recognized metrics such as the Chippaux–Šmiřák Index (CSI), the Staheli Index, and Clarke’s Angle, alongside various other tests and measurements established in scientific literature.A key feature of the application is its "Contraindications Screen," which highlights six clinical conditions requiring caution such as active plantar ulcers, acute osteomyelitis, Charcot neuro-osteoarthropathy, and advanced diabetic foot with loss of protective sensation. These warnings serve to remind the user of the necessity for a specialized medical evaluation before proceeding with any automated design recommendations. The application functions entirely without a constant internet connection after the initial download (as an offline-capable Progressive Web Application), making it suitable for use in clinics and centers with limited connectivity. It calculates multiple indicators from a single set of measurements and converts the results into preliminary design specifications such as functional insole height and arch-curve coordinates in a transparent and reviewable manner.Note:It is crucial to emphasize that Console serves solely as a technical and educational aid (a decision-support tool).The application does not replace direct specialized clinical examinations, diagnoses by the relevant medical team, or specialized radiological or dynamic assessments performed by licensed medical professionals.All displayed values and parameters serve as preliminary geometric starting points that must be reviewed by a qualified specialist prior to any clinical application or manufacturing.Important Disclaimer:Console aims to reduce the computational burden, standardize the presentation of results, and raise awareness regarding contraindications, while upholding the principle that the final decision always rests with the specialist physician and the orthotics expert.
