Increased electrical nerve stimulation threshold of the sciatic nerve in patients with diabetic foot gangrene: a prospective parallel cohort study.

Context: Peripheral neuropathy may affect nerve conduction in patients with diabetes mellitus.

Objective: This study was designed to test the hypothesis that the electrical stimulation threshold for a motor response of the sciatic nerve is increased in patients suffering from diabetic foot gangrene compared to non-diabetic patients.

Design: Prospective non-randomised trial with two parallel groups.
