Motor NCS electrode
placement
• The active recording electrode is placed over the endplate zone of a muscle
innervated by the tested nerve.
• The reference electrode is placed nearby in an electrically “quiet” area.
• The ground electrode is usually placed between the stimulating and recording
electrodes.
•
Using electrolytic gel between the skin and recording electrode improves the
“electrical contact” and reduces noise.
• When recording from a deep muscle, one may use a concentric or monopolar
needle for recording.
Sensory NCS
electrode placement
•
Surface disk or ring electrodes are placed over the skin where the tested nerve
is superficially located.
• The nerve is stimulated at sites where it is superficially located. The cathode of
the stimulator is oriented towards the active recording electrode.
Connect the
stimulating electrodes
To connect external stimulating electrodes to the Comfort Probe or Comfort Plus
Probe:
1. Remove the probe head.
2. Replace the probe head with the pin jack head.
3. Connect the
anode (+) and cathode (-) electrodes in the corresponding pin
jacks.
