[Effects of Aging and Sex Differences on the Median Nerve: Relationship Between Nerve Conduction Study and Ultrasonographic Cross-Sectional Nerve Area].
Objective: The aim of this study was to evaluate the relationship between nerve conduction and sonographic measurements of the median nerve, and to investigate the effects of aging and sex on nerve structure.
Methods: Measurements from both hands of 82 healthy volunteers were included in this study (45 men and 37 women, 38.9 ?17.7 years). The cross-sectional area(CSA) of the median nerve was evaluated at the carpal tunnel inlet (MA) and at the midpoint of the forearm (MB).
Results: The CSA of the median nerve at the MA was significantly correlated with age (r=0.501, P< 0.001), and distal motor latency (r=0.269, P<0.001). Although this study demonstrated the effects of the sex dif- ferences and aging on the CSA of the median nerve at MA, there was no significant effect at the MB.
Conclusions: Our study suggests that aging could affect median nerve structure, especially at the anatomical entrapment point. [Original].
