Sixty consecutive diabetic patients (15 with early and 13 with definite and/or combined autonomic neuropathy) with an ankle/brachial systolic pressure index (ABI) less than 0.20 +/- 0.08, underwent spinal cord stimulation after failed conservative or surgical treatment. The neuropathic status of the patients was evaluated before implantation and pedal TcpO2 measurements on the dorsum of the foot were performed.
