Aim: The aim of this study was to investigate the relation of the examination of saphenous, superficial peroneal, medial plantar and medial dorsal cutaneous nerve conduction with Diabetic Neuropathy and whether this examination may play a role in the early diagnosis of polyneuropathy or not.

Material and Method: The population included 52 patients with diabetes mellitus, attended the department of neurology, and internal medicine clinics at GATA Haydarpaşa Training Hospital and 30 volunteers with no systemic disease. In addition to the routine nerve conduction study; saphenous, superficial peroneal, medial plantar and medial dorsal cutaneous nerve conduction studies were performed to all groups.

Results: When the obtained data were evaluated, polyneuropathy, disease duration, and NSS (Neuropathy Symptom Scoring) in diabetic patients were found to be correlated with our results.

Conclusion: By the electrophysiological evaluation of the diabetic patients with a clinical suspect of polyneuropathy even with sural nerve conduction study results within normal values, saphenous, superficial peroneal medial plantar and medial dorsal cutaneous nerve conduction should be added to the routine examination.
