摘要

目的:F波是一种有价值的测量方法,可以提供神经近端和远端信息。经典的f波记录方法是从肢体的远端肌肉进行的,因此受到远端病变的影响。神经的传导速度受神经直径的影响。神经的直径越来越细,因为它产生分支并向远端传播。因此,神经的神经传导速度在神经近端比远端快,即使它们是同一神经的部分。本研究的目的是比较同一神经支配的近端和远端肌肉记录的F波的神经传导参数。这将提供额外的信息,并可能有价值的检测近端病理伴背景病理影响远端神经材料和方法包括26名健康志愿者正常的常规神经传导检查。所有参与者的尺侧和腓侧f波潜伏期均由同一神经支配的近端和远端肌肉记录。结果近端肌肉的f波潜伏期明显晚于远端肌肉。结论虽然近端肌肉记录到的F潜伏期比远端肌肉记录到的潜伏期要短,神经段/分支也更粗、更快,但近端肌肉记录到的潜伏期比远端肌肉记录到的潜伏期要长。这可能是由于记录电极的距离受到近端大块肌肉的皮下组织的影响。造成这种差异的一个原因可能是近端相对大块的肌肉有较高的不同步和时间分散。

Purpose The F- wave is a valuable measurement that provides information about both the proximal and distal parts of the nerve. Classical F-wave recording methods are performed from the distal muscles of the limb and so are affected from distal pathologies. Nerve conduction velocity of a nerve is affected by the diameter of the nerve. The diameter of a nerve gets thinner as it gives branches and travels distally. So it is expected that the nerve conduction velocity of a nerve is faster in proximal segment of the nerve than the distal part even they are the parts of the same nerve. The aim of this study is to compare the nerve conduction parameters of F waves recorded in proximal and distal muscles innervated by the same nerve. Which will provide additional information and may be valuable in detecting proximal pathologies accompanying background pathologies affecting the distal nerve Materials and Methods Twenty –six healthy volunteers who have normal routine nerve conduction studies are included in this study. The latencies of ulnar and peroneal F-waves of all participants were recorded from the proximal and distal muscles innervated by the same nerve. Results F-wave latencies recorded from proximal muscles were significantly later than the ones recorded from distal muscles. Conclusion Although the distances travelled by stimulation are shorter in F latencies recorded from proximal muscles , and the segment /branch of the nerve is expected to be thicker and faster however the latencies recorded from proximal muscles were longer than the ones recorded from distal muscles . This may be due to the distance of the recording electrodes effected by subcutaneous tissues in the proximal large mass muscles. One reason for this difference may be that the proximal relatively large mass muscles have higher desynchronization and temporal dispersions.
