Little or no practical decision-making data are available to the foot-care provider regarding the selection of orthotic materials used in therapeutic footwear. A device for simulating in-shoe forefoot conditions for the testing of orthosis materials is described. Materials are tested for their effectiveness by evaluating and comparing stress-strain and dynamic compression fatigue characteristics. The device, called the Cyclical Compression Tester (CCT), has been optimized for size, simplicity of construction, and cost. Application of the device ranges from the clinician deciding the useful life of single- and multidensity orthosis materials to the researcher characterizing materials for finite-element analysis modeling. This real-time CCT device and custom user interface combine to make an evaluation tool useful for testing how the pressure distribution of in-shoe materials changes over time in therapeutic footwear for those with peripheral neuropathy at risk for foot injury.
对于足部护理人员而言，几乎没有实用的决策数据可用于选择治疗性鞋类中使用的矫形材料。本文描述了一种用于模拟鞋内前足状况以测试矫形材料的装置。通过评估和比较应力-应变以及动态压缩疲劳特性来测试材料的有效性。该装置称为循环压缩测试仪（CCT），在尺寸、结构简单性和成本方面已进行了优化。该装置的应用范围广泛，从临床医生确定单密度和多密度矫形材料的使用寿命，到研究人员为有限元分析建模对材料进行特性描述。这种实时CCT装置和定制用户界面相结合，构成了一种评估工具，可用于测试对于有足部受伤风险的周围神经病变患者，治疗性鞋类中鞋内材料的压力分布如何随时间变化。
