[The F-wave in healthy subjects - origin, derivation, standardization]

The determination of the maximum F-wave conduction speed by means of the photographic superposition technique is a method that can be carried out in a technically simple manner and can give an insight into the peripheral motor neuron up to the anterior horn cell. The values can be determined in a more exact manner than the respective motor conduction speeds. Similar to the motor conduction speed, influencing factors are to be taken into consideration such as the temperature and the age of patients under ten years. The normal values for the N. ulnaris, radialis, fibularis and tibialis are submitted.
