通过分析频域中的步行足部压力图像，对具有三个水平足底感觉丧失的大量糖尿病患者进行了研究。糖尿病受试者的脚被扫描超过10个指定区域使用Semmes-Weinstein的尼龙单丝定量确定神经病变的三个级别。一个新的参数，功率比（PR，图像中的高频功率与总功率之比）被用来区分正常和糖尿病足的三个层次的感觉丧失离散。结果分析表明，糖尿病足（所有三个感觉丧失水平）与正常足相比，在足底溃疡形成发生率高的足部区域，甚至在感觉水平为45 mN的神经病变早期，PR值的差异非常显著（p<0.0005）。这一结果可能有助于在感觉丧失的初始阶段早期检测足底溃疡形成，并可供骨科医生考虑早期矫正方法，以保护这些足部免受神经性溃疡形成造成的进一步损害。
Studies were performed on a large number of diabetic patients with three levels of plantar sensation loss by analysing walking foot pressure images in the frequency domain. The feet of diabetic subjects were scanned over ten specified areas using Semmes-Weinstein's nylon monofilaments to determine quantitatively the three levels of neuropathy. A new parameter, the power ratio (PR, ratio of high frequency power to the total power in an image) was used to distinguish discretely between normal and diabetic feet in three levels of sensation loss. Analysis of results showed that the differences in PR values for diabetic feet (in all three levels of sensation loss) compared to normal feet were found to be highly significant (p<0.0005) in the areas of the foot where there was a high incidence of plantar ulcer formation, even at the early stage of neuropathy characterised by a sensation level of 45 mN. This result could help in the early detection of plantar ulcer formation in the initial stage of sensation loss and may be utilised by orthopaedic surgeons to consider early corrective methods to protect these feet from further damage due to neuropathic ulcer formation.
