Development of Simulated Testing System for Anti-inversion Property of Ankle Braces and Property Evaluation
Objective To develop a simulated testing system for evaluating anti-inversion properties of ankle braces,to objectively evaluate the anti-inversion properties of ankle braces,replace human experiments,and reduce the impact of subjective factors and individual differences on the tested results.Methods The system mainly includes a human ankle joint simulated model,a movement system,and a landing ramp to simulate the high-altitude landing process of the human body.The evaluation indicator is the maximum inversion angle of the ankle joint.The feasibility and reliability of the system were verified by testing a novel asymmetric semi-rigid ankle brace,using traditional ankle braces and bare foot as controls.Results The system has a simple structure,convenient operation,and high repeatability.The test results are objective and the data dispersion is small,which can objectively reflect the anti-inversion properties of ankle braces.Moreover,the novel asymmetric semi-rigid ankle brace shows favorable anti-inversion properties.Conclusion This study has solved the problems of low repeatability and large dispersion of human experimental data.This can provide some insights into further promoting the establishment of evaluation standards of the anti-inversion properties of ankle braces.
