Rehabilitation of the ankle joint complex after injury is often considered complete when the injured ankle has the same range of motion and strength as the uninjured contralateral limb even though this symmetry has never been quantified. The purpose of this investigation was to determine whether there were differences in the ankle joint complex range of motion between right and left legs. Total right and left ankle joint complex range of motion was measured on 18 subjects using a fixture allowing six degrees of freedom. A four-camera video system was used to record all range of motion movements. The results indicated that total dorsiflexion-plantarflexion, eversion-inversion, and abduction-adduction ranges of motion were not significantly different between right and left legs. However, separate abduction and adduction differences occurred, with the right foot tending to abduct more than the left, while the left foot tended to adduct more than the right. These differences in the abduction and adduction range of motion may be inherent in the measuring device. As a result of this study, it appears that the contralateral ankle joint complex can be used as a measure for establishing restoration of total range of motion of the ankle joint complex following injury.
踝关节复合体损伤后的康复通常在受伤的踝关节与未受伤的对侧肢体具有相同的活动范围和力量时被认为是完成了，尽管这种对称性从未被量化过。本研究的目的是确定左右腿之间踝关节复合体的活动范围是否存在差异。使用一个允许六个自由度的固定装置，对18名受试者的左右踝关节复合体的总活动范围进行了测量。使用四摄像头视频系统记录所有的活动范围动作。结果表明，左右腿之间的背屈-跖屈、外翻-内翻以及外展-内收的总活动范围没有显著差异。然而，单独的外展和内收存在差异，右脚的外展倾向比左脚更多，而左脚的内收倾向比右脚更多。这些外展和内收活动范围的差异可能是测量装置所固有的。作为本研究的结果，似乎对侧踝关节复合体可以用作确定踝关节复合体损伤后总活动范围恢复情况的一个衡量标准。
