F wave in nerve conduction study
WebF wave is a late response that follows the motor response (M) and is elicited by supramaximal electrical stimulation of a mixed or a motor nerve 4. F waves provide a means of examining transmission between stimulation sites in the arm and the leg and the related motor neurons in the cervical and lumbosacral cord. WebFeb 2, 2007 · If analyzed correctly, current reports would indicate that F-waves are the most sensitive and reliable nerve conduction study for evaluating polyneuropathies, can be …

WebThe concept that the F wave is ideally suited to assess proximal conduction was supported by the study. F Wave analysis added information in the evaluation of polyneuropathies, even if sensory nerve conduction studies were performed. In radiculopathies, F wave studies were particularly useful in milder cases, when the EMG data were inconclusive.
Web6. The CPT descriptor language, codes 95907-95913 describe one or more nerve conduction studies. For the purposes of coding, a single conduction study is defined as a sensory conduction test, a motor conduction test with or without an F-wave test, or an H-reflex test.
