摘要： 目的 探讨假脚储能性与实用性之间的关系。方法 通过对威萨脚、赛纳脚、1D35脚、E-S脚、1A30脚和SACH脚，6只不同性能假脚的仪器测试与临床测试，分析假脚动态储能性与截肢者在使用过程中的实用性之间的关系。结果 仪器测试显示，载荷位移量威萨脚、赛纳脚与SACH脚较小，1D35脚、E-S脚与1A30脚较大；1A30脚位能量损失与吸收比最大。临床测试反映能耗的总心率指标，步行时为威萨脚最小，SACH脚最大；跑步时为赛纳脚最小，1D35脚最大；反映能耗的耗时（s）指标，步行时为威萨脚最小，SACH脚最大；跑步时为赛纳脚最小，1D35脚最大；舒适度总评1A30脚最高，1D35脚和E-S脚最低。结论 对于假脚的实用性，节能性比储能性更重要。

Abstract: Objective To investigate the relationship between energy storage and clinical practicability of prosthetic feet.Methods Six different prosthetic feet were selected and tested the ratio between released energy and absorbed energy of these feet through a specially-designed equipment. Then, the differences on total cycles of heartbeat of the amputee were tested when he wore the six feet separately to walk and run.Results The total cycles of heartbeat of the amputee with feet of higher energy storage were apparently lower during running, but might be equal or even a little higher during walking.Conclusion The ability of energy-saving of a foot is more important than the ability of energy-storing.
