The purpose of the study is to monitor forces which are transmitted by a prosthesis for below-knee amputations to the stump of the amputee, through the patellar tendon (PT); to evaluate undesirable freedom between the socket and the stump; to alter the share of the PT in the weight-bearing process by augmenting the portion of the socket which supports it; to determine the limits of force that can be applied to it; and to suggest modifications to the Patellar-Tendon-Bearing socket which will produce optimal force distribution, taking into account universal considerations and individual variables. A special biaxial force transducer will be developed to measure two force components acting on the PT during locomotion. Linear displacement gauges will monitor axial and perpendicular freedom of the stump-socket. Fifteen amputees will be selected to participate in laboratorial testing. Each amputee will be fitted with an experimental prosthesis and will take part in three experimental sessions. During the tests, systematic changes to the socket will be administered and the influence of the recorded variables (during locomotion) will be observed.

这项研究的目的是监测力的传递， 一种用于对截肢者的残肢进行膝下截肢的假肢， 通过髌腱（PT）;评价不良自由度 在《易经》和《易经》之间， 通过增加承窝的部分来实现承重过程， 支持它;确定可以施加于 它;并建议修改髌骨肌腱轴承插座 这将产生最佳的力量分配，考虑到 普遍考虑和个体变量。 特殊的双轴 力传感器将被开发用于测量两个力分量 在运动过程中作用于PT。 线性位移计将 监测桩承的轴向和垂直自由度。 十五 将挑选截肢者参加实验室测试。 每个 截肢者将安装一个实验性的假肢， 参加三个实验性会议。 在测试过程中，系统 将管理对套接字的更改， 将观察记录的变量（在运动期间）。
