糖尿病并发周围神经病变,应用运动神经传导速度(MCV)确定病变部位,以便发现亚临床型患者。还发现神经末端潜伏期延长较MCV减慢更明显,且与病程、控制程度、及微血管并发症有明显相关。Hoffman反射潜伏期均有延长,较MCV、末端潜伏期更为敏感,脑电图、脑血流图检查则无意义。 Diabetic patients with peripheral neuropathy, the application of motor nerve conduction velocity (MCV) to determine the lesion site, in order to find subclinical patients. It was also found that the latency of neuroendocrine lesion was more obvious than that of MCV, and was obviously related to the course of disease, degree of control and microvascular complications. Hoffman reflex latency are longer, more sensitive than MCV, terminal latency, EEG, cerebral blood flow test is meaningless.
