Objective To investigate the difference of shear wave velocity at different positions of the median nerve in healthy individuals.Methods A total of 56 healthy volunteers(112 wrists) were included.The shear wave velocity of median nerve at the proximal and distal carpal bones levels were examined by shear wave elastography.The difference between the shear wave velocity of the two levels were compared.The correlations between shear wave velocity and age
sex and body mass index(BMI)were analyzed.Results The shear wave velocity at the proximal carpal bone level of the median nerve was(3.80±0.45)m/s
95% confidence interval was 3.67~3.93 m/s.The shear wave velocity at the distal carpal bone level was(4.63±0.47) m/s
95%confidence interval was 4.49-4.76 m/s.The shear wave velocity at the same level of the median nerve in males was higher than that in females(P=0.005).The shear wave velocity of the median nerve of the two levels was positively correlated with age(r=0.301
0.376
P=0.037

and was no correlation with BMI.Conclusion The shear wave velocity of the median nerve in different regions of the wrist is different.Both sex and age can affect the shear wave velocity.
