本研究提出了一种通过足背运动学数据识别常见体育活动中踝关节扭伤运动的方法。六名男性受试者在实验室进行了300次模拟旋后扭伤试验和300次非扭伤试验。在右足背安装8个运动传感器，采集三维线加速度和角速度运动学数据，用于训练支持向量机（SVM）模型进行识别。结果表明，最好的识别方法只需要一个运动传感器位于内侧跟骨，并在另一组6名受试者进行300次模拟旋后扭伤试验和300次非扭伤试验中验证了该方法。该方法的准确率为91.3%，可用于踝关节扭伤检测的移动运动传感器系统的开发。(C) 2010 Elsevier Ltd.版权所有。
This study presented a method to identify ankle sprain motion from common sporting activities by dorsal foot kinematics data. Six male subjects performed 300 simulated supination sprain trials and 300 non-sprain trials in a laboratory. Eight motion sensors were attached to the right dorsal foot to collect three-dimensional linear acceleration and angular velocity kinematics data, which were used to train up a support vector machine (SVM) model for the identification purpose. Results suggested that the best identification method required only one motion sensor located at the medial calcaneus, and the method was verified on another group of six subjects performing 300 simulated supination sprain trials and 300 non-sprain trials. The accuracy of this method was 91.3%, and the method could help developing a mobile motion sensor system for ankle sprain detection. (C) 2010 Elsevier Ltd. All rights reserved.
