PURPOSE
This study aimed to assess the dynamics of the distance between the talus and lateral malleolus during the stance phase of gait and confirm any sex differences.
METHODS
The distance between the talus and lateral malleolus was quantified during gait in 25 healthy participants. Noninvasive ultrasound with three-dimensional motion analysis was used to assess the kinematic properties during the walking stance phase.
RESULTS
The distance between the talus and lateral malleolus widened immediately after initial contact, narrowed during mid-stance, and widened during the stance cycle in all participants. The distance was significantly wider in females, especially during the early and terminal stance phases, contributing to differences in sagittal mobility.
CONCLUSIONS
Quantitative measurement of the anterior talofibular ligament attachment distance may aid in the early detection of ankle abnormalities. The dynamic characteristics observed in females during gait may be associated with chronic ankle instability or osteoarthritis risk.
目的
本研究旨在评估步态站立期距骨与外踝之间距离的动态变化，并确认是否存在性别差异。
方法
对25名健康参与者在步态过程中距骨与外踝之间的距离进行量化。使用非侵入性超声结合三维运动分析来评估步行站立期的运动学特性。
结果
在所有参与者中，距骨与外踝之间的距离在初始接触后立即变宽，在站立中期变窄，并在站立周期中再次变宽。女性的该距离明显更宽，尤其是在站立早期和末期，这导致了矢状面活动度的差异。
结论
距腓前韧带附着距离的定量测量可能有助于早期发现踝关节异常。女性在步态中观察到的动态特征可能与慢性踝关节不稳定或骨关节炎风险相关。
