Basic principles of motor nerve conduction. Physiological factors affecting conduction studies: age, height, temperature, anatomical variants. Non-physiological factors affecting conduction studies: electrodes size and site of recording, interelectrode distance, unde- overstimulation, anodic stimulation, effect of filters, gain and analysis time, errors in measurements of distance. Biophysical and electrophysiological effects onnerve conductyion of axonal degeneration, segmental demyelination, paranodal and nodal disruption. Conduction block and temporal dispersion. To verify the learning process, during the lesson exemplificative recordings will be dysplayed and anwers collected by the televoter provided to the students. A practical demostration of motor nerve conduction will be also given.
