测定正常人正中神经、尺神经、腓总神经和胫后神经中最大运动纤维、感觉纤维和反射纤维的传导速度。 H 反射纤维的传导率最大，传入纤维次之，运动纤维最小。所有纤维的近端部分传导速度都比远端部分快。 50岁以后，神经传导速度下降，上肢比下肢更明显，涉及所有测试的纤维，且远端更为突出。与此相关的是，腕部正中神经和肘部尺神经的传导速率轻度减慢。在一组没有周围神经病变临床体征或症状的糖尿病患者中，传导速度轻度下降。在所有神经和纤维中都注意到这一点，但在远端节段中最为突出。在一组具有周围神经病变临床体征和症状的糖尿病患者中，传导速度下降幅度更大。这涉及所有纤维和神经，并且在远端最为突出。手腕处的正中神经和肘部的尺神经（慢性受压部位）也有明显的减慢。
Conduction velocity in the largest motor, sensory, and reflex fibers in the median, ulnar, common peroneal, and posterior tibial nerves was determined in normal man. The rate of conduction was greatest in the H reflex fibers, followed by the afferent fibers, and was least in the motor fibers. Proximal segments in all fibers conducted faster than distal ones. After the age of 50, there was a decrease in nerve conduction velocity, which was more apparent in upper than lower extremities, involved all fibers tested, and was more prominent distally. Associated with this, there was mild slowing of the conduction rate of the median nerve at the wrist and ulnar nerve at the elbow. In a group of patients with diabetes mellitus without clinical signs or symptoms of peripheral neuropathy, there was a mild decrease in conduction velocity. This was noted in all nerves and fibers but was most prominent in distal segments. In a group of patients with diabetes mellitus, with clinical signs and symptoms of peripheral neuropathy, there was a greater decrease in conduction velocity. This involved all fibers and nerves and was most prominent distally. There was also prominent slowing in the median nerve at the wrist and ulnar nerve at the elbow, sites of chronic compression.
