For submental EMG, insert the electrode leads into the EMG channels of the Nox A1 recorder and
attach the electrodes to the patient’s chin. The front chin electrode goes into the F input, the left chin
electrode goes into the 1 input, and the right chin electrode goes into the 2 input.
Before electrodes are placed it is important to inspect the skin locations and make sure the electrodes
are placed on a dry and clean location that has no small abrasions and wounds. To prepare the skin, it
is recommended to clean the skin with water and abrasive skin prepping gel (55 50 10 Nuprep ECG &
EEG Abrasive Skin Prepping Gel). In some cases, if the skin is very oily it can be necessary to use wipes
with alcohol. The electrodes are then applied to the skin by use of suitable gel or paste (Ten20
Conductive EEG Paste) ensuring bio-compatibility and electrical contact.
