It is fundamental to the intended success of electrostimulation
applications that electrodes are positioned sensibly.
We recommend that you consult your doctor to establish the ideal
electrode positions for your intended application area.
The figure on the display is intended as an initial aid to help you
position the electrodes.
The following applies to the selection of electrode positions:
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.
The following guideline applies to selection of the electrode
distance:
• Sensible distance: approx. 5 – 15 cm
• At distances below 5 cm, the unit primarily stimulates surface
structures intensively
• At distances in excess of 15 cm, large areas and deep structures
are stimulated very weakly
Relationship between electrodes and muscle fibre structures
Adapt the current flow direction to the fibre
structure of the muscle according to the muscle
layer you would like to treat. If you are targeting
superficial muscles, position the electrodes in
parallel to the fibre structure (A – B / C – D) and if
you are targeting deeper layers of tissue, position
the electrodes across the fibre structure. You can
do this by positioning electrodes as crosses (i.e. diagonally), such as
A – D / B – C.
As part of pain relief treatment (TENS) using the digital EMS/
TENS unit and its 2 separately adjustable channels and 2
adhesive electrodes each, it is advisable either to position the
electrodes of a channel so that the area affected by the pain
is between the electrodes or to position one electrode directly
on the area affected by the pain and the other electrode at a
minimum distance of 2 – 3 cm.
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, we once again recommend positioning electrodes
as crosses.
Tip for the massage function: always use all four electrodes for
optimum treatment.
Use the electrodes on skin that is clean and preferably
free from hair and grease in order to prolong the life of the
electrodes. If required, 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 is reduced to the lowest level. Apply
the electrode again and reset the desired impulse intensity.
7. Customisable programs
(Applies for TENS 13-15, EMS 33-35)
The programs TENS 13-15 and EMS 33-35 can be customised
according to your needs.
C
A
TENS 13 program
TENS 13 is a program that you can also customise. In this program,
D D
B B
you can set the impulse frequency to between 1 and 150 Hz and the
impulse width to between 80 and 250 µs.
1. Place the electrodes on the desired area for treatment (for
positioning suggestions see section "6.4 Information regarding
the positioning of electrodes") and connect them to the device.
2. Select the TENS 13 program as described in section "5.2 Starting
application" (step 3 to step 5).
