To examine the relative diagnostic sensitivity of various F wave parameters.
Normal values for minimum, mean, and maximum F wave latency, chronodispersion, and persistence in the four major motor nerves were established and systematically applied to at least four separate categories of patients (radiculopathies, polyneuropathies, mononeuropathies, and others). F Waves were studied both isolated and in comparison with other motor nerve conduction parameters.
F Chronodispersion was the most often abnormal parameter, particularly in lumbosacral radiculopathies. Minimum F wave latency was more useful in polyneuropathies. Compared with minimum F wave latency, F chronodispersion was able to identify most additional cases.
F Wave studies should include minimum F wave latency and chronodispersion.
研究各种F波参数的相对诊断敏感性。
确定四大运动神经的最小、平均和最大F波潜伏期、时限离散度及出现率的正常值，并系统地应用于至少四类不同患者（神经根病、多发性神经病、单神经病及其他）。分别对F波进行研究，并与其他运动神经传导参数进行比较。
F波时限离散度是最常出现异常的参数，尤其在腰骶神经根病中。最小F波潜伏期在多发性神经病中更有用。与最小F波潜伏期相比，F波时限离散度能识别出更多其他病例。
F波研究应包括最小F波潜伏期和时限离散度。
