skin. Skin preparation for the reference pad site may be beneficial if the EMG signal
exhibits a wandering baseline. The EMG Transmitter can be secured in place using
Noraxon supplied double sided adhesive tape and/or elastic straps. Straps are
recommended if very dynamic movements are expected.
The EMG Transmitter allows for interchangeable terminal lead wires for
attachment to disposable electrodes. The two lead wires are offset with one longer than
the other by an amount equal to the standard 2 cm spacing for surface EMG electrodes.
The 2-pin lead wire connector can be inserted either way into the EMG Transmitter to
facilitate attachment to the surface electrodes. There are 2 lead lengths currently available:
10 cm and 15 cm leads.
3.3 Skin Preparation
In order to ensure proper signal transmission, the surface of the skin under the
electrode and under the transmitter must be cleaned and cleared of anything. This will
ensure proper contact and signal transmission.
3.3.1 Removal of hair
If the participant has hair where the electrodes will be placed, this must be shaved
without the use of shaving cream, which leaves a film and impedes electrode adhesion and
electrical conduction.
3.3.2 Cleaning of skin
The skin under the electrode must also be cleaned. This can be done using a
special abrasive conductive cleaning paste, but the use of an alcohol and a gauze pad is
sufficient. The skin must be cleaned and abraded enough to remove a layer of skin.
Surface Electrode Placement
Once the site has been properly prepared, the electrode and transmitter
can be placed. Here are a few guidelines for electrode placements:
1.
Wet-gel electrodes have the best skin impedance values
