Abstract: Objective

To measure the parameters of median nerve under ultrasound in patients with diabetes mellitus to explore the relationship between ultrasonic parameters and nerve conduction study.

Methods

From June to November, 2019, 79 diabetic patients were divided into diabetic peripheral neuropathy (DPN) group (n = 37) and non-DPN group (n = 42) according to the diagnosis. Their right median nerve were measured cross-sectional area (CSA) and the proportion of hypoechoic areas (HA) 5 cm and 10 cm proximal to the wrist (CSA-5, CSA-10, HA-5 and HA-10, respectively) with sonography; while the conductive latency and velocity of right median nerves were measured with nerve conductive study.

Results

CSA-5, CSA-10 and HA-10 were more in DPN group than in non-DPN group (|Z| > 2.282, P < 0.05). HA-5 correlated with the motor conductive latency (r = 0.264, P < 0.05) and velocity (r = -0.270, P < 0.05); HA-10 correlated with the abnormal sensory conductive latency (r = 0.234, P < 0.05) and velocity (r = 0.363, P < 0.01), and the motor conductive latency (r = 0.235, P < 0.05) and velocity (r = -0.255, P < 0.05).

Conclusion

DPN can be found under sonography, some of them are related with the nerve electrophysiology, which may be a useful tool to screen DPN.
