Cross-sectional area (CSA) reference values of lower extremity nerves using ultrasonography have only been reported in a few studies and have been limited to white populations.
For this study, 94 healthy Korean volunteers were recruited for measurement of the CSA at 7 sites of lower extremity nerves. The side-to-side difference in CSA was calculated for each nerve, and reference ranges were derived. External validity evaluation for the reference values was performed with 10 newly recruited volunteers at a different institution.
Nerve CSA was correlated significantly with body mass index, weight, and height; however, the absolute value of the side-to-side difference had no significant correlation with demographic factors. The external validity was adequate for all sites, ranging from 80% to 100%.
The lower extremity nerve CSA values obtained in this study may provide normal reference values for the Asian population.
使用超声测量下肢神经横截面积（CSA）的参考值仅在少数研究中有所报道，且仅限于白人人群。
在本研究中，招募了94名健康的韩国志愿者，用于测量下肢神经7个部位的CSA。计算每条神经CSA的左右差异，并得出参考范围。在另一家机构对10名新招募的志愿者进行参考值的外部有效性评估。
神经CSA与体重指数、体重和身高显著相关；然而，左右差异的绝对值与人口统计学因素无显著相关性。所有部位的外部有效性都足够，范围从80%到100%。
本研究中获得的下肢神经CSA值可能为亚洲人群提供正常参考值。
