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.
开发了一种体外模拟器，以再现尸体足部标本站立期步态的运动学和动力学。通过一个倾斜角度和力控制的平移台施加地面反作用力，该平移台上安装了一个压力测量平台；胫骨旋转由一个伺服电机再现。对足部屈肌和伸肌肌群的九条肌腱施加力，并测量三维后足和前足运动。该模型基于体内运动学和动力学测量进行了验证。发现总体上吻合良好，但也有一些例外情况，包括步态线略偏外侧。
