F波是运动神经元逆向激活产生的低振幅反应。它们可能不会在每次刺激后出现，并且在潜伏期、振幅和配置方面固有地可变。对F波进行有意义的分析需要了解F波的这些特征以及对它们的生理学的理解。这些功能的F波以及他们的生理学进行了审查。这一点很重要，因为F波是临床神经生理学中最常用的研究之一，围绕F波使用的许多争议都与未能充分考虑F波分析的要求有关。这些要求包括需要记录的F波数量、应评估的参数以及记录F波的肌肉。如果分析正确，目前的报告将表明，F波是最敏感和可靠的神经传导研究评估多发性神经病，可能是异常的局灶性近端神经功能障碍，可以至少作为针肌电图定义腰骶神经根病的敏感性，并可以提供一个有意义的生理窗口到中枢神经系统疾病。支持这些声明及其临床相关性的报告进行了讨论。
F-waves are low amplitude responses produced by antidromic activation of motoneurons. They may not appear after each stimulus and are inherently variable in latency, amplitude, and configuration. Meaningful analysis of F-waves requires an appreciation of these characteristics of F-waves as well as an understanding of their physiology. These features of F-waves as well as their physiology are reviewed. This is important since F-waves are one of the most frequently used studies in clinical neurophysiology and much of the controversies surrounding the use of F-waves relates to a failure to adequately consider the requirements of F-wave analysis. These requirements include the number of F-waves that need to be recorded, the parameters that should be evaluated, and the muscle from which the F-waves are recorded. If analyzed correctly, current reports would indicate that F-waves are the most sensitive and reliable nerve conduction study for evaluating polyneuropathies, can be abnormal in focal proximal nerve dysfunction, can be at least as sensitive as needle electromyography for defining lumbosacral radiculopathies, and can provide a meaningful physiological window into disorders of the central nervous system. Reports supporting these statements and their clinical relevance are discussed.
