足部/脚踝假体样机的试点评估报告。这个原型的设计和制造的目的是在步态站立阶段的中间部分提供减少的踝关节僵硬，并增加(即，更正常的)膝关节在站立阶段的运动范围。作者的评估包括将现有的足部/脚踝假体原型以及传统的实心脚踝垫足(SACH)安装到一名膝盖以下(BK)截肢的健康志愿者身上。作者使用视频运动分析系统和测力平台测量了该个体在行走过程中的下肢关节运动学和动力学。这些测量可以直接比较假体踝关节的僵硬程度和受累的一侧膝关节运动，以及假体踝关节的力矩和功率。
Reports on a pilot evaluation of a prototype foot/ankle prosthesis. This prototype has been designed and fabricated with the intention of providing decreased ankle joint stiffness during the middle portion of the stance phase of gait, and increased (i.e., more normal) knee range of motion during stance. The authors' evaluation involved fitting the existing prototype foot/ankle prosthesis, as well as a traditional solid ankle cushioned heel (SACH) foot, to an otherwise healthy volunteer with a below-knee (BK) amputation. The authors measured this individual's lower extremity joint kinematics and kinetics during walking using a video motion analysis system and force platform. These measurements permitted direct comparison of prosthetic ankle joint stiffness and involved side knee joint motion, as well as prosthetic ankle joint moment and power.
