Most electrodiagnosis texts advocate cathode distal stimulation (CDS) for nerve conduction, but suggest cathode proximal stimulation (CPS) for F waves, because of anodal block. We postulated that CDS and CPS elicit F waves of similar persistence. We studied 657 (207 median, 204 ulnar, 136 tibial, and 110 peroneal) nerves in 225 consecutive subjects. In the median nerve, CDS elicited F waves of slightly greater persistence than CPS. Stimulator orientation did not affect F-wave persistence in the remaining nerves.
大多数电诊断学教科书都提倡在进行神经传导检查时采用阴极远端刺激（CDS），但由于阳极阻滞，建议在检测F波时采用阴极近端刺激（CPS）。我们推测，CDS和CPS引发的F波具有相似的出现率。我们对225名连续受试者的657条神经（207条正中神经、204条尺神经、136条胫神经和110条腓总神经）进行了研究。在正中神经中，CDS引发的F波出现率略高于CPS。刺激器方向对其余神经的F波出现率没有影响。
