Nerve conduction studies are used to aid in the diagnosis of distal symmetric polyneuropathy (DSP). It is unclear whether bilateral lower extremity nerve conduction studies (NCS) are needed when evaluating for suspected DSP.
We retrospectively analyzed NCS from patients who presented to the University of Michigan electromyography laboratory between July 1, 2016 and December 31, 2017 with symptoms of DSP to assess agreement and correlation between left and right lower extremity NCS parameters.
We found significant agreement between abnormalities in individual nerve parameters of the left and right lower extremities of 105 patients, most notably in the sural nerve. In the 53 patients with bilateral sural, peroneal, and tibial studies, there was also significant agreement between whether the left and right met electrodiagnostic criteria for DSP (κ = 0.77).

神经传导研究用于辅助诊断远端对称性多发性神经病（DSP）。在评估疑似 DSP 时，是否需要双侧下肢神经传导研究（NCS）尚不清楚。
我们回顾性分析了 2016 年 7 月 1 日至 2017 年 12 月 31 日期间在密歇根大学肌电图实验室就诊的有 DSP 症状的患者的 NCS，以评估左、右下肢 NCS 参数之间的一致性和相关性。
我们发现 105 例患者左右下肢单个神经参数异常之间存在显著一致性，在腓肠神经中最为明显。在 53 例双侧腓浅、腓深和胫后神经研究中，左右是否符合电诊断 DSP 标准之间也存在显著一致性（κ=0.77）。
