The distribution of motor fiber conduction velocities (FCVs) of the ulnar and peroneal nerves in patients with polyneuropathy was estimated using F tacheodispersion, a technique based on F wave latencies. Twenty-three ulnar and 23 peroneal nerves were studied. Three groups of nerves were identified according to conventional, M response, and F wave measurements: those with all parameters normal (group 1), those with abnormal F wave parameters only (group 2), and those with all parameters abnormal (group 3). Application of F tacheodispersion to nerves in group 1 revealed a shift of the distribution of FCVs toward the lower normal values in 6 of 7 nerves. In group 2, a significant proportion of FCVs were below the lower normal limits despite normal maximum conduction velocity estimated by the M response. In group 3, all nerve fibers were abnormally slow. The results indicate that application of F tacheodispersion in clinical practice will increase sensitivity of nerve conduction studies and enable quantitative estimation of conduction in a motor nerve fiber population.
使用基于F波潜伏期的F离散技术，估计了多神经病患者尺神经和腓总神经的运动纤维传导速度（FCV）分布。研究了23条尺神经和23条腓总神经。根据传统、M反应和F波测量结果，将神经分为三组：所有参数正常的神经（第1组）、仅F波参数异常的神经（第2组）和所有参数异常的神经（第3组）。对第1组神经应用F离散技术显示，7条神经中有6条的FCV分布向较低的正常值偏移。在第2组中，尽管通过M反应估计的最大传导速度正常，但相当一部分FCV低于正常下限。在第3组中，所有神经纤维传导均异常缓慢。结果表明，在临床实践中应用F离散技术将提高神经传导研究的敏感性，并能够对运动神经纤维群体的传导进行定量估计。
