The addition of an extrinsic rearfoot post to an orthotic device allows the podiatric practitioner to modify the function of the device. Specifically, rearfoot posts are used to allow for a more inverted heel position at contact, to provide greater resistance to abnormal frontal plane motion of the calcaneus and to provide for motion for shock absorption. The authors present nine prescription variables that each provide for a specific functional change to be incorporated into the orthotic device.
在矫形器械上添加外部后足柱，可让足病医生改变器械的功能。具体而言，后足柱用于使足跟在接触时处于更内翻的位置，为跟骨在额状面的异常运动提供更大阻力，并为减震提供运动功能。作者介绍了九个处方变量，每个变量都能为矫形器械带来特定的功能改变。
