The most common neuromuscular ultrasound abnormality in carpal tunnel syndrome is enlargement of the median nerve near the distal wrist crease, but sometimes the median nerve enlarges in the palm, just distal to the transverse carpal ligament. This study was conducted to devise a protocol for measuring the median nerve in the palm and to generate reference values for nerve cross‐sectional area at this site.

使用超声在手掌处的正中神经的横截面积参考值。

腕管综合征中最常见的神经肌肉超声异常是远端腕部折痕附近的正中神经增大，但有时正中神经在手掌中增大，正好位于腕横韧带的远端。进行这项研究的目的是设计一种用于测量手掌中部神经的协议，并为该部位的神经横截面积生成参考值。
