Electrode Distance
The larger the distance between electrodes, the larger the stimulated tissue volume. This applies to the area and 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: 5-15 cm (2-6 in)
• At distances less than 5 cm (2 in), the unit primarily stimulates surface structures intensively.
• At distances more than 15 cm (6 in), 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 2-3 cm (1-1½ in) 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.
NOTE:
• 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 should come loose during use, the impulse intensity of both channels drops to the
lowest level. Apply the electrode again and reset the desired impulse intensity.
