| Abstract: | OBJECTIVE—To examine the relative diagnosticsensitivity of various F wave parameters. METHODS—Normal values for minimum, mean, andmaximum F wave latency, chronodispersion, and persistence in the fourmajor motor nerves were established and systematically applied to atleast four separate categories of patients (radiculopathies,polyneuropathies, mononeuropathies, and others). F Waves were studiedboth isolated and in comparison with other motor nerve conduction parameters. RESULTS—F Chronodispersion was the most oftenabnormal parameter, particularly in lumbosacral radiculopathies.Minimum F wave latency was more useful in polyneuropathies. Comparedwith minimum F wave latency, F chronodispersion was able to identifymost additional cases. CONCLUSIONS—F Wave studies should include minimumF wave latency and chronodispersion. |
