Ultrasound can potentially identify nerves and guide recording and stimulating electrode placement for nerve conduction studies (NCS). This prospective study was performed to determine whether ultrasound guidance of sural NCS results in higher action potential amplitude, fewer stimuli required, lower stimulus strength required, and less pain experienced.
Fourteen healthy individuals underwent bilateral sural NCS, both with and without ultrasound guidance. Studies were separated by at least 48 h, and the order of testing was randomly assigned.
Ultrasound guidance resulted in significantly fewer stimuli and lower stimuli strength required to obtain supramaximal responses (P < 0.01-0.03). Ultrasound guidance required significantly more time to perform than standard sural NCS (P < 0.01). There was no difference in sural nerve amplitude or pain rating between the 2 groups.

超声技术可能有助于识别神经，并引导记录和刺激电极的放置，从而进行神经传导研究（NCS）。本前瞻性研究旨在确定超声引导是否能提高运动神经动作电位幅度、减少所需刺激次数、降低所需刺激强度并减轻疼痛。
14 名健康个体接受了双侧腓肠神经 NCS，包括有和没有超声引导的检查。两次检查至少间隔 48 小时，且测试顺序随机分配。
超声引导可显著减少获得最大反应所需的刺激次数和刺激强度（P<0.01-0.03）。与标准的腓肠神经 NCS 相比，超声引导需要更多的时间来完成（P<0.01）。两组的腓肠神经幅度或疼痛评分无差异。
