Selected combinations of multidensity orthotic materials were tested under simulated walking conditions found in the forefoot of diabetic patients. Materials were compared for therapeutic effectiveness by their stress/strain properties and dynamic compression set. Results showed that all of the multidensity materials experienced losses in performance throughout the testing period of 100,000 cycles, with the greatest losses occurring within the first 10,000 cycles. Of the materials tested, Poron + Plastazote #2 and Spenco + Microcel Puff Lite had the highest dynamic material strain and the lowest dynamic compression set over 100,000 cycles. In comparison, these are better multidensity combinations than the others tested to use as therapeutic orthoses in footwear for diabetic patients.
在模拟糖尿病患者前足行走的条件下，对多种不同密度的矫形材料组合进行了测试。根据材料的应力/应变特性和动态压缩永久变形来比较其治疗效果。结果显示，在100,000次循环的测试期间，所有多种密度材料的性能都出现了损失，最大的损失发生在最初的10,000次循环内。在测试的材料中，Poron + Plastazote #2和Spenco + Microcel Puff Lite在100,000次循环中具有最高的动态材料应变和最低的动态压缩永久变形。相比之下，这些多种密度组合比其他测试组合更适合用作糖尿病患者鞋类的治疗性矫形器。
