The dorsal movement of the Achilles tendon during ankle rotation is restricted by anatomical obstructions. Previously, we demonstrated that the anatomical obstruction provides a gain (gain) in the proximal displacement of the calcaneus compared to the change in the Achilles tendon length. Here, we empirically validate and extend our previous modeling study by investigating the effects of a broad range of obstruction locations on gain. The largest gain could be achieved when the obstruction was located on the most ventral and distal sides within the physiological range of the Achilles tendon, irrespective of the ankle position.
跟腱在踝关节旋转过程中的背侧运动受到解剖结构的限制。此前，我们证明，与跟腱长度的变化相比，该解剖结构使跟骨近端位移产生了增益。在此，我们通过研究广泛的阻塞位置对增益的影响，对我们之前的建模研究进行了实证验证和拓展。当阻塞位于跟腱生理范围内最腹侧和最远端时，无论踝关节处于何种位置，均可实现最大增益。
