The results showed an increased mean jitter value, fiber density and abnormal percentage both in EDC and AT muscles in group 1 and II diabetic patients comparing to the normal controls. These findings suggest an impaired or immatured neuromuscular junctions and an evidence of reinnervation through axonal sprouting in the diabetic patients either with or without nerve conduction abnormalities. In conclusion, the changes of axonal degeneration and reinnervation are the main pathophysiological mechanism of diabetic neuropathy, and the SFEMG is more sensitive than routine nerve conduction study in the diagnosis of diabetic neuropathyKeyword Axonal degeneration , diabetes mellitus , neuropathy , single fiber electromyography
