开发了一种体外模拟器来重现尸体足部标本的站立期步态的运动学和动力学。地面反作用力通过倾斜角度和力控制的平移台施加，平移台上安装有压力测量平台；胫骨旋转由伺服电机再现。对足部屈肌群和伸肌群的九个肌腱施加力，并测量后足和前足的三维运动。该模型根据体内运动学和动力学测量进行了验证。人们发现，除了一些例外情况，其中包括稍微更横向的步态线之外，总体上一致。
An in vitro simulator was developed to reproduce the kinematics and kinetics of stance phase gait on cadaver foot specimens. Ground reaction force was applied by a tilting angle- and force-controlled translation stage upon which a pressure measuring platform was mounted; tibial rotation was reproduced by a servomotor. Force was applied to nine tendons of the foot flexor and extensor muscle groups, and three-dimensional hind- and forefoot motion was measured. The model was verified based on in vivo kinematic and kinetic measurements. It was found to be in good general agreement with some exceptions which include a slightly more lateral gait line.
