The cross-sectional area (CSA) reference values of the lower extremity nerves in Asians have been rarely reported. For this study, 107 sex- and age-matched, healthy subjects with a mean age of 46 years (range, 24-75 years) were recruited. All subjects underwent standardized nerve conduction studies of the upper and lower extremities. The CSA was measured unilaterally at 12 sites in the lower extremity nerves, including the femoral, lateral femoral cutaneous, sciatic, common peroneal, superficial peroneal, deep peroneal, tibial, and sural nerves. The CSA significantly correlated with height, weight, and body mass index. The CSA was significantly larger in males than females at most nerves except for the lateral femoral cutaneous, common peroneal (fibular head), and superficial peroneal nerves (distal calf). There was no statistically significant difference between the age groups except for the tibial nerve (ankle). The results of this study provide CSA reference values for the lower extremity nerves including small branches and the values can be useful in the ultrasonographic investigation of various peripheral neuropathies in East Asian populations.
亚洲人下肢神经的横截面积（CSA）参考值很少有报道。在这项研究中，我们招募了 107 名年龄和性别匹配的健康受试者，平均年龄为 46 岁（范围为 24-75 岁）。所有受试者均接受了上肢和下肢的标准化神经传导研究。CSA 单侧测量 12 个下肢神经部位，包括股神经、股外侧皮神经、坐骨神经、腓总神经、腓浅神经、腓深神经、胫神经和腓肠神经。CSA 与身高、体重和体重指数显著相关。除了股外侧皮神经、腓总神经（腓骨头）和腓浅神经（小腿远端）外，男性的 CSA 大多数神经均大于女性。除了胫神经（踝部）外，各年龄组之间无统计学差异。本研究的结果提供了包括小分支在内的下肢神经 CSA 的参考值，这些值可用于东亚人群各种周围神经病变的超声研究。
