Abstract:
Objective To design an anti-inversion performance evaluation system for ankle braces and validate its performance.Methods The system was composed of a simulation system,an inversion angle acquisition system,a lateral tension acquisition system for ankle joint and a data collection and procession system.The simulation platform made of aluminum alloy consisted of a standing platform and a landing pad,and the landing pad was made up of a platform and a slope for landing;the inversion angle acquisition system included markers,an image acquisition device and a fill light.The lateral tension acquisition system involved in a tension sensor,a detection sensor and an elastic cloth for fixation.The data collection and procession system comprised of a computer or smartphone,iXControl software,iXViewer software and a cell phone App that received real-time data from the lateral ankle tension acquisition device.The system developed underwent performance validation when applied to evaluating anti-inversion performance of volunteers without or with flexible or new braces.The traditional EMG testing method was used for EMG data acquisition for volunteers without or with flexible or new braces,and the consistency was explored between the testing results by the traditional method and the system.Results The system developed could evaluate the anti-inversion performance of ankle braces by simulating the process of ankle inversion during human high-altitude landing,and the results had high consistency with those by traditional EMG testing methods.Conclusion The system developed with simple structure and easy operation evaluates the anti-inversion performance of ankle braces.[Chinese Medical Equipment Journal,2024,45(11):21-26]
