The dual Euler angles method has been proposed as an alternative approach to describe the general spatial human joint motion. In this study, the dual Euler angles method was applied to study the three-dimensional motion of the ankle complex. The methodology for obtaining dual Euler angles of the ankle complex was developed by using a "Flock of Birds" electromagnetic tracking device. The repeatability of the methodology was studied based on the intertester and intratester variability analysis. Finally kinematic coupling characteristics of the ankle complex during dorsiflexion-plantarflexion, eversion-inversion, and abduction-adduction were analyzed according to the parameters of the dual Euler angles.
双欧拉角方法已被提出作为描述人体一般空间关节运动的一种替代方法。在本研究中，双欧拉角方法被应用于研究踝关节复合体的三维运动。利用“飞鸟”电磁跟踪装置开发了获取踝关节复合体双欧拉角的方法。基于测试者间和测试者内变异性分析研究了该方法的可重复性。最后，根据双欧拉角参数分析了踝关节复合体在背屈 - 跖屈、外翻 - 内翻和外展 - 内收过程中的运动耦合特性。
