In an in vivo investigation of eight healthy volunteers, three dimensional ankle/foot kinematics were analyzed by roentgen stereophotogrammetry in 10 degrees steps of motion from 30 degrees of plantar flexion to 30 degrees of dorsiflexion of the foot. The study included all of the joints between the tibia and the first metatarsal, as well as the talocalcaneal joint, and was performed under full body load. Although the talocrural joint was found to account for most of the rotation around the transverse axis occurring from 30 degrees of plantar flexion to 30 degrees of dorsiflexion, there was a substantial contribution from the joints of the arch. This was seen particularly in the input arc from 30 degrees of plantar flexion to the neutral position, where the dorsiflexion motion of these joints amounted to 10% to 41% of the total transverse axis rotation.
在一项针对八名健康志愿者的体内研究中，通过X线立体摄影测量法，以10度步幅分析了从足跖屈30度到背屈30度的三维踝/足运动学。该研究涵盖了胫骨与第一跖骨之间的所有关节以及距下关节，并在全身负重情况下进行。尽管发现距小腿关节在从足跖屈30度到背屈30度发生的围绕横轴的旋转中占大部分，但足弓关节也有很大贡献。这在从足跖屈30度到中立位的输入弧中尤为明显，在该弧段这些关节的背屈运动占横轴总旋转的10%至41%。
