The purpose of this study was to investigate the effects of a total-contact insole with and without subthreshold mechanical random noise on the balance control in diabetic patients with mild-to-moderate peripheral neuropathy. Twenty diabetic patients with mild-to-moderate neuropathy was recruited to this study. A total-contact insole was prototyped and vibratory motors were embedded into it. The parameters of the center of pressure (amplitude, velocity, and phase plane portrait) were analyzed after 30-minute walks with the shoe only, the shoe with vibro-medical insole with and without vibrations in eyes open and closed condition. The center of pressure amplitude, velocity, and phase plane portrait in the anterior-posterior and medio-lateral directions were significantly decreased using a vibro-medical insole without vibration in the eyes open condition (p < 0.05), as compared to the shoe, and with vibro- medical insole with vibration in both eyes open and closed conditions (p < 0.05) compared to the shoe. A significant drop was observed in the center of pressure amplitude, velocity and phase plane portrait parameters when the vibro-medical insole with vibration was used compared to vibro- medical insole without vibration in eyes closed condition (p < 0.05). The use of vibro-medical insoles was found to improve the patient's balance control, as compared to the shoe. In the eyes closed condition, an improvement in the balance control was observed only with vibro-medical insole with vibration rather than vibro-medical insole without vibration or the shoe. Current finding suggest that a combination of the total-contact insole with vibration may improve the balance control remarkably in diabetic patients with mild-to-moderate neuropathy.

带有和不带有振动的振动医学鞋垫对患有轻度至中度周围神经病的糖尿病患者的平衡控制的影响。

这项研究的目的是研究具有和不具有亚阈值机械随机噪声的全接触鞋垫对患有轻度至中度周围神经病变的糖尿病患者的平衡控制的影响。该研究招募了20名患有轻度至中度神经病的糖尿病患者。设计了一种全接触式鞋垫，并将振动电机嵌入其中。仅使用鞋子行走30分钟后，即可分析压力中心的参数（振幅，速度和相平面肖像），该鞋子带有振动医疗眼镜的鞋子在睁眼和闭眼情况下均带有和不带有振动。压力幅度，速度，与鞋和带振动的振动医疗鞋垫相比，在睁开眼睛的情况下不振动的振动医疗鞋垫，前后表面和中外侧方向的相平面肖像均显着降低（p <0.05）与鞋子相比，在两只眼睛睁开和闭着的情况下（p <0.05）。当在闭眼的情况下使用振动的振动医疗鞋垫与不振动的振动医疗鞋垫相比时，观察到压力幅度，速度和相平面肖像参数的中心显着下降（p <0.05）。与鞋子相比，发现使用振动医疗鞋垫可以改善患者的平衡控制。在闭眼的情况下 仅使用振动的振动医疗鞋垫，而不振动或振动的振动医疗鞋垫观察到平衡控制有所改善。目前的发现表明，在轻度至中度神经病的糖尿病患者中，全接触式鞋垫与振动相结合可以显着改善平衡控制。
