9. Electrode Positioning
It is critical to position the electrodes properly. Consult your
doctor to establish the ideal electrode positions for your
intended application area. The above chart is intended as
an initial aid to help position the electrodes.
Electrode Distance
The larger the distance between electrodes, the larger the
stimulated tissue volume. This applies to the area and the
depth of the tissue volume. At the same time, however, the
stimulation intensity of the tissue falls the further the electrodes
are apart. As a result, greater distances between electrodes
mean a larger tissue volume is stimulated, but less intensively.
Consequently, you must increase the impulse intensity to boost
stimulation.
• Proper distance between electrodes: 2-6 inches (5-15 cm)
• At distances less than two inches (5 cm), the unit primarily
stimulates surface structures intensively.
• At distances more than 15 cm, large areas and deep
structures are stimulated very weakly.
Relationship between electrodes and muscle fiber
structures
Adapt the current flow direction to the fiber structure of the
muscle according to the muscle layer you would like to treat.
If you are targeting surface muscles, position the electrodes
in parallel to the fiber structure (A – B / C – D)
and if you are targeting deeper layers of tissue,
position the electrodes across the fiber
structure. You can do this by positioning
electrodes as crosses (i.e. diagonally), such as
A-D/B-C.
NOTE: As part of pain relief treatment (TENS) using separately
adjustable channels and two adhesive electrodes each, either
position both electrodes of a channel so the area affected
by pain is between the electrodes or position one electrode
directly on the area affected by pain and the other electrode
at least 1-1½ inches (2-3 cm) away.
You may use the electrodes of the second channel to
simultaneously treat additional areas affected by pain or use
them in conjunction with the electrodes of the first channel to
restrict the area affected by pain (position electrodes opposite).
In this case, position electrodes as crosses.
Tips:
• Use the electrodes on skin that is clean and preferably
free from hair and grease in order to prolong the life of the
electrodes. For best results, clean the skin with water and
remove hair prior to treatment.
• If an electrode comes loose during use, the impulse
intensity of both channels drops to the lowest level. Apply
the electrode again and reset the desired impulse intensity.
10. Customizable Programs (TENS
programs 13-15, EMS programs 33-35)
TENS programs 13-15 and EMS programs 33-35 can be
customized according to your needs.
