背景：小腿三头肌挛缩与足和踝部病变有关。跟腱挛缩已被证明会使足底压力从足跟转移到前足。本研究的目的是确定孤立的腓肠肌挛缩是否有类似影响，并评估腓肠肌或比目鱼肌挛缩对中足足底压力的影响。
方法：10个新鲜冷冻的膝下尸体标本在10度背屈板上足部不受约束，加载至79磅（350N）的足底力。以3磅为增量施加静态腓肠肌或比目鱼肌力的组合，并获取后足、中足和前足区域的足底压力记录。
结果：随着小腿三头肌力量增加，前足和中足所承受的足底力百分比增加，而后足所承受的百分比降低（p
Background: Triceps surae contractures have been associated with foot and ankle pathology. Achilles tendon contractures have been shown to shift plantar foot pressure from the heel to the forefoot. The purpose of this study was to determine whether isolated gastrocnemius contractures had similar effects and to assess the effects of gastrocnemius or soleus contracture on midfoot plantar pressure. Methods: Ten fresh frozen cadaver below-knee specimens were loaded to 79 pounds (350N) plantar force with the foot unconstrained on a 10-degree dorsiflexed plate. Combinations of static gastrocnemius or soleus forces were applied in 3-lb increments and plantar pressure recordings were obtained for the hindfoot, midfoot, and forefoot regions. Results: The percentage of plantar force borne by the forefoot and midfoot increased with triceps surae force, while that borne by the hindfoot decreased (p
