Diyabetik Ayak Gelişiminde Elektrofizyolojik Risk Faktörü: Posterior Tibiyal Sinir İleti Bozukluğu.

Objective: Vascular insufficiency, polyneuropathy, infection, and pressure are among the multiple factors involved in the development of diabetic foot as a delayed complication of diabetes mellitus. In this study we aimed to determine the leading nerve conduction pathologies operating in diabetic lesions of the lower extremities. Method: In this study, 20 diabetic patients with diabetic foot and polyneuropathy, 20 patients with only polyneuropathy, and 20 diabetics without any of the stated complications were evaluated retrospectively. Age, duration of diabetes, haemoglobin A1c, and electroneuromyography findings of these three groups were compared. Results: Patients with diabetic foot were older and had longer duration of diabetes and higher levels of haemoglobin A1c. Peroneal sensorimotor nerve conduction studies did not differ between the patients with diabetic foot and those with polyneuropathy but without diabetic foot. Posterior tibial motor nerve conduction velocity and amplitude were significantly lower in the first group (p<0.05). Posterior tibial motor nerve conduction velocity was inversely related to the duration of diabetes (p<0.01, r= -0.9). There was no relation with other daemographic features and metabolic values. Discussion: Decreases in posterior tibial motor nerve conduction velocity and M-response amplitude are risk factors for diabetic foot. We are the opinion that patients with ENMG eliciting such results should be followed up more carefully. [ABSTRACT FROM AUTHOR]
