Performing an Exam
Example Motor Nerve Conduction Test
Position and secure the electrodes to your patient according to your conventions
for the type of test you are performing.
Note: The recording electrode is placed on a muscle, even though the interest is
in the conduction along the nerve.
The nerve is stimulated using surface electrodes at two or more sites where the
nerve is located superficially. The stimulator is oriented so that the cathode of the
stimulator faces the active recording electrode.
Negative voltage applied to the black (-) input jack produces an upward
deflection on the screen display. Use the black input jack as the
active electrode
and the red input jack as the reference or inactive electrode for a negative-up
convention.
