Abstract

Background: Muscle disorders may cause a change in plantar pressures by the misalignment on the foot during gait phases. Therefore, corns or calluses develop at the plantar regions, and diabetic foot ulcers follow for severe cases, although it can be prevented and even treated by podiatric approaches with patient-specific therapeutic insoles and footwear. Although the importance of a threshold value of 200 kPa in peak plantar pressure reduction has been highlighted as a standard to prevent reulceration in the diabetic foot, it may not be possible to ensure this pressure reduction for each patient.

Methods: In this study, three types of ethylene-vinyl acetate have been used to optimize the off-loading performance for predetermined early-stage diabetic foot ulcer scenarios by means of baropodometric plantar pressure analyses and finite element method for each gait phase.

Results: The total cost of the manufacturing for this study was reduced to $10.26 and it was performed in 24.6 minutes. In addition, the off-loaded pressure was increased by 2.3 times and the volume of the off-loading geometry was increased 8.12 times based on the foam polymer used.

Conclusions: Consequently, improved off-loading was obtained and a standard was proposed for the first time to calculate the off-loading performance before manufacturing of the therapeutic insole model to ensure a better recovery period.

糖尿病伤口专用鞋垫的设计、制造和生物力学验证方法，以实现更好的恢复。

在步态阶段，由于足部错位，肌肉失调可能会导致足底压力发生变化。因此，足底区域会出现鸡眼或胼胝，严重者会出现糖尿病足溃疡，尽管这种情况可以通过足病治疗方法和患者专用的治疗鞋垫和鞋袜来预防甚至治疗。虽然 200 千帕的阈值被认为是防止糖尿病足再次溃疡的黄金标准，但可能无法确保为每位患者都降低压力。在这项研究中，通过对每个步态阶段的气压足底压力分析和有限元法，利用 3 种乙烯-醋酸乙烯酯优化了预先确定的早期糖尿病足溃疡情况下的卸载性能。这项研究的制造总成本降至 10.26 美元，耗时 24.6 分钟。此外，根据所使用的泡沫聚合物，卸载压力增加了 2.3 倍，而卸载几何体的体积增加了 8.12 倍。因此，该研究获得了更好的卸载效果，并首次提出了在制造治疗鞋垫模型前计算卸载性能的标准，以确保更长的恢复期。
