Abstract

Background

Individuals with diabetes are often prescribed standard of care accommodative insoles to provide extra cushioning and prevent ulcers. Our pressure-based 3D printed custom accommodative insoles have proven effective in reducing plantar pressure in individuals with diabetes. Given that older adults with diabetes have exacerbated balance deficits due to neuropathy, it is essential to examine the impact of these custom accommodative insoles on postural balance in individuals with diabetes. Therefore, the purpose is to examine the effects of custom accommodative insoles on balance during quiet standing in individuals with diabetes.

Methods

Standard of care and pressure-based 3D printed custom accommodative insoles were designed from foot impressions obtained from ten participants with diabetes. Postural balance was assessed during quiet standing for three conditions: no insole, standard of care, and pressure-based 3D printed custom accommodative insoles. Center of pressure measures were computed for all three conditions, and differences between the three insole conditions were evaluated.

Findings

There were no significant differences in the center of pressure measures across the insole conditions. Use of standard of care and pressure-based 3D printed custom accommodative insoles did not negatively affect the postural balance during quiet standing compared to the no insole condition.

Interpretation

This pilot study provides useful information on how the custom accommodative insoles used to prevent ulcers in individuals with diabetes affect postural balance. Static postural balance is not adversely impacted with the use of custom accommodative insoles in individuals with diabetes.

标准护理和基于压力的3d打印定制调节鞋垫对糖尿病患者静态平衡的影响：一项试点研究

背景：糖尿病患者经常被要求使用可调节的鞋垫，以提供额外的缓冲和预防溃疡。我们基于压力的3D打印定制调节鞋垫已被证明可以有效降低糖尿病患者的足底压力。鉴于老年糖尿病患者由于神经病变而加剧了平衡缺陷，有必要研究这些定制的适应性鞋垫对糖尿病患者姿势平衡的影响。因此，目的是检查定制适应性鞋垫对糖尿病患者安静站立时平衡的影响。方法根据10例糖尿病患者的足印设计标准护理和基于压力的3D打印定制调节鞋垫。在安静站立的三种情况下评估姿势平衡：无鞋垫、标准护理和基于压力的3D打印定制调节鞋垫。计算了所有三种情况下的压力中心测量值，并评估了三种鞋垫条件之间的差异。研究结果：在不同鞋垫条件下，压力测量中心没有显著差异。与没有鞋垫的情况相比，使用标准护理和基于压力的3D打印定制调节鞋垫对安静站立时的姿势平衡没有负面影响。这项初步研究提供了有用的信息，说明用于预防糖尿病患者溃疡的定制适应性鞋垫如何影响姿势平衡。在糖尿病患者中，使用定制的适应性鞋垫不会对静态姿势平衡产生不利影响。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
