A set of design criteria for sensing the shape of an above-knee (AK) stump is presented and used as the basis for evaluating various shape sensing technologies. A mechanical probe type shape sensing system is described and its use in quantifying the external shape of the AK stump is discussed as it relates to generating a grid for finite element analysis in CAD/CAM studies and comparing the segmental volumes of the loaded and unloaded stump. This study also discusses a method that uses circumferential measurements to compute total and incremental volumes of the stump.
提出了一组用于感知膝上（AK）残肢形状的设计标准，并以此为基础评估各种形状传感技术。描述了一种机械探头式形状传感系统，并讨论了其在量化AK残肢外部形状方面的应用，因为这涉及到在CAD/CAM研究中生成用于有限元分析的网格，以及比较加载和未加载残肢的节段体积。本研究还讨论了一种利用圆周测量来计算残肢总体积和增量体积的方法。
