This study aims to provide some guidelines for the use of soles on below-knee walking casts. Whole-body energy changes during the single limb support phase of the gait cycle have been quantified in twenty volunteer subjects fitted with below-knee casts and each wearing one of five soles in turn. Simple gait analysis was carried out with a Kistler force plate and an Apple II microcomputer, the data were sampled at 50 Hz. Three commercial soles and two 'home made' ones were used; it was generally found that the commercial products produced a more energy efficient gait. Some recommendations are included regarding the design of soles to be used in this clinically demanding situation.
本研究旨在为膝下行走支具使用鞋底提供一些指导方针。在二十名佩戴膝下支具且依次穿着五种鞋底之一的志愿者中，对步态周期单肢支撑阶段的全身能量变化进行了量化。使用奇石乐测力板和苹果II型微型计算机进行了简单的步态分析，数据以50赫兹的频率采样。使用了三种商用鞋底和两种“自制”鞋底；一般发现商用产品产生的步态能量效率更高。针对在这种临床要求较高的情况下使用的鞋底设计提出了一些建议。
