A new procedure of serial motor nerve conduction velocity (NCV) measurements with the use of "superimposed response waves" technique (or double stimulus technique) was performed on 29 normal subjects. Six peripheral nerves were tested once a week for four to six weeks. A total of 760 NCV measurements were thus obtained to try to assess the magnitude of error in serial NCV testings. With the double stimulus technique employed, a significant reduction in variations of serial NCV measurements was found. The overall standard deviation of four to six consecutive NCV measurements in the 34 subjects was 1.3 meters per second with a coefficient of variation of 2.4%. These findings obtained with the double stimulus technique have proven to be approximately three times more accurate than results obtained by investigators who studied nerve conduction velocity measurement variation with single stimulus standard NCV testing techniques.
采用“叠加反应波”技术（或双刺激技术）对29名正常受试者进行了一系列运动神经传导速度（NCV）测量的新程序。每周对六条周围神经进行一次测试，持续四至六周。因此，共获得760次NCV测量结果，以试图评估连续NCV测试中的误差大小。采用双刺激技术时，发现连续NCV测量的变化显著减少。34名受试者四至六次连续NCV测量的总体标准差为每秒1.3米，变异系数为2.4%。这些通过双刺激技术获得的结果已被证明比使用单刺激标准NCV测试技术研究神经传导速度测量变化的研究者所获得的结果精确约三倍。
