AIMS/INTRODUCTION: Neuropathy is a common complication of diabetes that reduces balance by disrupting vision, and the sensory and vestibular systems. This is important in older adults who are more at risk of falling. Studies show that improving the sensory mechanisms through insoles can improve balance in people with balance disorders. As textured insoles have recently been considered for improving balance disorders, this study aimed to investigate the immediate effect of textured insoles on the balance of patients with diabetic neuropathy.
A total of 17 patients with diabetic neuropathy participated in this quasi-experimental study. The studied variables were the general balance index, posterior-anterior balance index and medial-lateral balance index, which were measured in three conditions: (i) soft textured insoles; (ii) hard textured insoles; and (iii) without textured insoles. A Biodex balance device was used for this purpose.
In the general balance index, there was a significant difference between all the studied conditions. In the posterior-anterior balance index, there was a significant difference between without textured insole and hard textured insoles, and also soft and hard textured insoles. In the medial-lateral balance index, there was a significant difference between the hard textured insoles and without textured insoles, and also soft and hard textured insoles (P < 0.05).
Wearing textured insoles can increase the balance in patients with diabetic neuropathy. This can be due to its effect on the sensory feedback of the soles, improving the proprioception and tactile sensors that are the main sources of balance.
目的/引言：神经病变是糖尿病的常见并发症，它通过干扰视觉、感觉和前庭系统来降低平衡能力。这对于更容易跌倒的老年人来说尤为重要。研究表明，通过鞋垫改善感觉机制可以改善平衡障碍患者的平衡能力。由于最近已经考虑使用纹理鞋垫来改善平衡障碍，因此本研究旨在调查纹理鞋垫对糖尿病神经病变患者平衡的即时影响。
共有 17 名糖尿病神经病变患者参与了这项准实验研究。研究的变量是一般平衡指数、前后平衡指数和内外平衡指数，这些指数在三种情况下进行测量：（i）软质纹理鞋垫；（ii）硬质纹理鞋垫；（iii）无纹理鞋垫。为此目的使用了 Biodex 平衡设备。
在一般平衡指数中，所有研究条件之间存在显著差异。在后前平衡指数中，无纹理鞋垫与硬质纹理鞋垫之间以及软质和硬质纹理鞋垫之间存在显著差异。在内外平衡指数中，硬质纹理鞋垫与无纹理鞋垫之间以及软质和硬质纹理鞋垫之间存在显著差异（P<0.05）。
穿纹理鞋垫可以增加糖尿病神经病变患者的平衡能力。这可能是由于它对足底感觉反馈的影响，改善了本体感觉和触觉传感器，这是平衡的主要来源。
