摘　　要：目的:设计一种踝护具防内翻性能评价系统,并对其性能进行验证。方法:该系统主要由模拟平台、内翻角度采集系统、踝关节外侧张力采集装置及数据收集与处理系统等组成。模拟平台采用铝合金材料制作,由站立平台和着陆台组成,其中着陆台包括着陆平台和着陆斜台;内翻角度采集系统由标记物、影像采集装置和补光灯组成;踝关节外侧张力采集装置由张力传感器、检测传感器、固定用弹力布组成;数据收集与处理系统主要包括计算机或智能手机、iXControl软件、iXViewer软件及接收踝关节外侧张力采集装置实时数据的手机App等。采用该系统对裸足、穿戴柔性踝护具和新型踝护具的志愿者进行防内翻性能测试,验证该系统评价踝护具防内翻性能的可行性。采用传统肌电测试法对裸足、穿戴柔性踝护具和新型踝护具的志愿者进行肌电数据采集,验证该系统的测试结果与传统肌电测试法测试结果的一致性。结果:该系统可以较好地模拟人体高空着陆过程中的踝关节内翻过程,评价踝护具的防内翻性能,且测试结果与传统的肌电测试法具有较好的一致性。结论:该系统结构简单、操作便利,可有效评价踝护具的防内翻性能。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.
