Abstract

BACKGROUND

Neuropathic diabetic foot ulceration may be prevented if the mechanical stress transmitted to the plantar tissues can be modified. Orthotic therapy is one practical method commonly used to maintain tissue integrity. Orthotic design must consider the materials chosen for use in fabrication and profile of the device because both aspects influence the performance and durability of the device. Published research evaluating the physical properties of materials commonly used in the manufacture of orthoses for patients with diabetes is limited. This study investigated the physical properties of materials used to fabricate orthoses designed for the prevention of neuropathic diabetic foot ulcers.

METHODS

Fifteen commonly used orthotic materials were selected for testing: four specifications of 6.4-mm Poron (Rogers Corp., Gent, Belgium), 3.2-mm Poron, three densities of 12-mm Ethylene Vinyl Acetate (EVA), 12-mm low-density plastazote, two depths (6.4-mm, 3.2-mm) of Cleron (Algeo Ltd., Liverpool, UK), Professional Protective Technology (PPT), and MaxaCane (Algeo Ltd, Liverpool, UK). The density, resilience, stiffness, static coefficient of friction, durability, and compression set of each material were tested, ranked, and allocated a performance indicator score.

RESULTS

The most clinically desirable dampening materials tested were Poron 96 (6-mm) and Poron 4000 (6-mm). High density EVA (Algeo Ltd., Liverpool, UK) and Lunacell Nora EVA (Freudenberg, Weinhein, Germany) possessed the properties most suitable to achieve motion control. The data present a simple and useful comparison and classification of the selected materials.

CONCLUSIONS

Although this information should not be used as a single indicator for assessing the suitability of an orthotic material, the results provide clinically relevant information relating to the physical properties of orthotic materials commonly used in the prevention of neuropathic diabetic foot ulcers.

摘要

背景

如果能够改变传递至足底组织的机械应力，神经性糖尿病足溃疡或许可以预防。矫形器疗法是常用的维持组织完整性的一种实用方法。矫形器设计必须考虑制造中所选用的材料以及器械的外形，因为这两个方面都会影响器械的性能和耐用性。已发表的评估糖尿病患者矫形器常用材料物理特性的研究有限。本研究调查了用于制造旨在预防神经性糖尿病足溃疡的矫形器的材料的物理特性。

方法

选择15种常用的矫形材料进行测试：6.4毫米的四种规格的Poron（比利时根特市罗杰斯公司）、3.2毫米的Poron、三种密度的12毫米乙烯-醋酸乙烯共聚物（EVA）、12毫米低密度普拉扎托、两种厚度（6.4毫米、3.2毫米）的Cleron（英国利物浦阿尔乔有限公司）、专业防护技术（PPT）以及MaxaCane（英国利物浦阿尔乔有限公司）。对每种材料的密度、弹性、硬度、静摩擦系数、耐用性和压缩永久变形进行测试、排名并赋予一个性能指标分数。
