The large majority of prosthetic feet are aimed at low-heeled shoes, with a few models allowing a heel height of up to 5 cm. However, a survey by the American Podiatric Medical Association indicates that most women wear heels over 5 cm; thus, current prosthetic feet limit most female prosthesis users in their choice. Some prosthetic foot components are heel-height adjustable; however, their plantar surface shapes do not change to match the insole shapes of the shoes with different heel heights. The aims of the study were therefore (1) to develop a model that allows prediction of insole shape for various heel height shoes in combination with different shoe sizes and (2) to develop and field-test low-cost prototypes of prosthetic feet whose insole shapes were based on the new model. An equation was developed to calculate insole shapes independent of shoe size. Field testing of prototype prosthetic feet fabricated based on the equation was successful and demonstrated the utility of the equation.
绝大多数假肢脚是针对低跟鞋设计的，只有少数型号允许高达5厘米的鞋跟高度。然而，美国足病医学协会的一项调查表明，大多数女性穿的高跟鞋超过5厘米；因此，目前的假肢脚限制了大多数女性假肢使用者的选择。一些假肢脚部件的鞋跟高度是可调节的；然而，它们的足底形状不会改变以匹配不同鞋跟高度鞋子的鞋垫形状。因此，本研究的目的是：（1）开发一个模型，能够结合不同鞋码预测各种鞋跟高度鞋子的鞋垫形状；（2）开发并实地测试鞋垫形状基于新模型的低成本假肢脚原型。开发了一个方程来计算与鞋码无关的鞋垫形状。基于该方程制造的假肢脚原型的实地测试取得了成功，并证明了该方程的实用性。
