F-waves are able to assess both afferent and efferent loops of the alpha motor neuron in its entirety. As such, various properties of F-wave motor nerve conduction are analyzed in nerve conduction studies (NCS), and often used to assess polyneuropathies, resulting from states of neuronal … See more In neuroscience, an F wave is one of several motor responses which may follow the direct motor response (M) evoked by electrical stimulation of peripheral motor or mixed (sensory and motor) nerves. F-waves are the … See more Several measurements can be done on the F responses, including: • minimal and maximal F wave latencies (ms) - frequently … See more • H reflex • Electromyography (EMG) See more F-waves are evoked by strong electrical stimuli (supramaximal) applied to the skin surface above the distal portion of a nerve. This impulse travels both in orthodromic fashion (towards the See more F waves can be analyzed by several properties including: • amplitude (μV) - height or voltage of F wave • duration (ms) - length of F wave See more WebAbstract. The F wave results from backfiring of antidromically activated anterior horn cells. Thus, it helps assess motor conduction along the entire length of the peripheral … WebConduction velocity shows how quickly the impulse travels along the axon (normal conduction velocity lower limb >39 m/s b; upper limb >49 m/s). Amplitude describes the maximal impulse of the action potential a nerve generates.
