Electromyographic evoked potential meter

All patients underwent neurophysiological examinations by electromyographic evoked potential meter according to the protocol of the manufacturer (Natus Neurology, USA). These neurophysiological examination tests were performed in our hospital by staff in the electrophysiology room for medical use. The information of motor conduction fiber velocity of the ulnar nerve, radial nerve, median nerve, tibial nerve, and common peroneal nerve, as well as the sensory conduction fiber velocity of the ulnar nerve, radial nerve, median nerve, and sural nerve, was collected from the medical histories of patients.

Neurophysiological examinations were conducted on patients diagnosed with T2DM at our hospital. These examinations were carried out in the Electrophysiology room by trained personnel, using an electromyographic evoked potential meter in accordance with the manufacturer’s protocol (Natus Neurology, USA). The data of nerve conduction velocity was recorded from the medical histories of the enrolled T2DM patients. The average values of the bilateral nerve conduction velocities were computed for further analysis.
