Abstract

In this investigation we measured sural and radial sensory potentials and the sural/radial amplitude ratio (SRAR) in 49 patients with diabetes and diabetic sensorimotor polyneuropathy (DSP) according to consensus criteria. Forty-five (92%) of the patients had a Toronto Clinical Neuropathy Score (TCNS) ≤5, which is consistent with a diagnosis of DSP. Using a threshold for SRAR of <0.21, we found no advantage of using the SRAR over the sural nerve potential amplitude alone in sensitivity for identification of DSP.

摘要

在这项研究中，我们根据共识标准测量了 49 例糖尿病和糖尿病感觉运动多发性神经病（DSP）患者的腓肠和桡神经感觉电位以及腓肠/桡神经幅度比（SRAR）。45 例（92%）患者的多伦多临床神经病变评分（TCNS）≤5，这与 DSP 的诊断一致。使用 SRAR<0.21 的阈值，我们发现 SRAR 对单独使用腓肠神经电位幅度在 DSP 的识别方面的敏感性没有优势。
