4.3 Safety Precautions for Stimulation Current Intensity

Please observe the following safety precautions when adjusting the intensity of the
stimulation current applied to the patient:
•
Always bear in mind that the patient may display an altered sensitivity, and
may therefore not be properly aware of the current strength.
•
Be especially careful in measuring doses for blonde, light-skinned patients,
and for thin-skinned patients.
•
Explain to patients that if they experience unpleasant or even burning
sensations under one of the electrodes, they must point this out. (Where
available, give the patient the release button for interrupting the therapy.)
•
Pay particular attention, when using current forms with a high galvanic
component (G, UR, IG 30, T/R with pulse lengths above 50 ms and
accompanied by pauses below 200 ms), that the recommended intensity
of 0.1 mA/cm2 of active electrode surface area is not exceeded.
•
If you use electrodes of various different sizes during a treatment, the
smaller of the two electrodes, the so-called "active electrode", is always
decisive when measuring the intensity.

4.3.1 Recommended Intensities

The maximum intensity to be applied depends on the type and size of the
electrodes. Please observe the maximum intensities as specified here!
4.3.1.1 Plate Electrodes
Type Size of Plate Electrodes
(sponge bags; cm)
EF 10 4.0 x 3.0 (5.5 x 5,0)
EF 50 8.0 x 6.0 (11.0 x 9,0)
EF 100 12.0 x 9.0 (14.0 x 12,0)
EF 200 17.0 x 11.0 (20.0 x 15,0)

4.4 Preparations and Attaching the Electrodes

To prepare the electrodes, proceed as follows:
(1) Prior to attaching the electrodes, make sure that the intensity control<6> is
turned down to 0!
(2) Plug the patient lead into the patient lead connector <10> with the guide
rails facing upward.
(3) Plug the plate electrodes or junction lead for adhesive electrodes into the
corresponding connectors of the patient lead (page 6).
Make sure that the polarity is correct.
(4) Prior to attaching the electrodes, check whether the patient's skin shows scars
or lesions. Avoid such areas by all means!
