The load on the talocrural joint during three different ways of lifting was compared and discussed with biomechanical and ergonomical aspects. Healthy subjects lifted a 12.8-kg box from floor to table-level with bent and straight knees. The loading moment of force about the bilateral ankle axis was calculated by means of a computerized static sagittal plane model. Electromyography was recorded from the tibial anterior, gastrocnemius, and soleus muscles. The mean maximum loading moment was found to be 68 newton-meters with an estimated joint compressive force of 2.9 times body weight. The lowest loading moments obtained were associated with lifting the burden between bent knees and close to the pelvis.
比较并从生物力学和人体工程学方面讨论了三种不同提举方式下距小腿关节的负荷情况。健康受试者分别以屈膝和直膝的方式将一个12.8千克的箱子从地面举到桌面高度。借助计算机化的静态矢状面模型计算了双侧踝关节轴周围的加载力矩。记录了胫骨前肌、腓肠肌和比目鱼肌的肌电图。发现平均最大加载力矩为68牛顿米，估计关节压缩力为体重的2.9倍。获得的最低加载力矩与在屈膝且靠近骨盆的位置提举重物有关。
