  • Title: [Direct measurement of the conduction velocity of single motor axons in man].
    Author: Dengler R, Stein RB.
    Journal: EEG EMG Z Elektroenzephalogr Elektromyogr Verwandte Geb; 1987 Jun; 18(2):68-71. PubMed ID: 3111829.
    Abstract:
    The conduction velocity (CV) of single motor axons was measured in the ulnar and median nerve. Stimuli of submaximal intensities were delivered at the wrist and at the elbow using surface electrodes. The responses of single motor units were recorded by tungsten or steel microelectrodes. Changes of the stimulus intensity and of the position of the stimulation electrodes and subtraction of the responses frequently allowed the potential of the same motor unit to be identified following stimulation at both sites and to calculate its axonal CV. In all individuals, axonal CV's from the low to the high velocity range (40 to 63 m/s) could be measured. The method may provide a new approach to the investigation of various disorders of the peripheral nerve.
