Abstract

Nerve conduction study has been an important part of electrodiagnosis and has been utilized as a clinical diagnostic technique in diabetic neuropathy. But conduction study of the more proximal segment has been a few reports. This study demonstrated segmental method for obtaining orthodromic motor nerve conduction and mixed nerve conduction, and antidromic distal sensory nerve conduction in diabetic group and normal group. The purpose of the study was to determine diagnostic value of segmental nerve conduction in diabetic neuropathy. The results were as follows: 1. Significant difference at P<0.01 between diabetic group and normal group; in median motor terminal latency, median motor nerve conduction velocity at axilla-elbow segment and elbow-wrist segment, median sensory nerve conduction velocity at wrist-elbow segment, ulnar motor and sensory conduction velocity at wrist-elbow segment, posterior tibial motor nerve conduction velocity at popliteal fossa-ankle segment, peroneal motor nerve conduction velocity at fibula head-ankle segment. 2. No significant difference at P>0.05 between diabetic group and normal group; in ulnar motor terminal letency, ulnar sensory nerve conduction velocity at axilla-Erb's point segment and finger-wrist segment, peroneal motor terminal latency and peroneal motor nerve conduction velocity at popliteal fossa-fibula head segment, posterior tibial motor terminal latency, sural sensory nerve conduction velocity. 3. The nerve conduction of proximal segment is more statistically significant than that of distal segment.
