General Information

Intended use

The EMP 4 PRO device has been designed for the transcutaneous stimulation of muscles
and nerves and may not be used for any other purposes.

Safety instructions

Please read the operating instructions carefully before using the EMP 4 PRO.

• The EMP 4 PRO is only to be used for stimulation purposes on one patient at any one time.

• Only use the EMP 4 PRO with original accessories.

• The size of the electrodes should to be not less than 2 cm².

• The electrodes should be positioned in such ways that the current flow will not cross
through the heart.

• Keep the EMP 4 PRO away from water or other liquids. Do not drop the EMP 4 PRO, do
not use it inappropriately or expose it to extreme temperatures or high levels of humidity
(not less than 10 °C or more than 40 °C or a relative humidity of more than 90 %).

• Do not use the EMP 4 PRO if it is not working properly or if it has been damaged in any way.

• Be careful when using the EMP 4 PRO near or on children. Keep the unit away from children.

• Always store the EMP 4 PRO in its case to protect it from damage and dust.

• To avoid reciprocal interference, the EMP 4 PRO should not be operated in the vicinity
of other electronic devices. If this is not possible, the various unit functions should
be closely monitored during operation so that proper use in accordance with the
regulations is ensured.

• The simultaneous connection to the patient of a high frequency surgical unit can lead
to burning under the electrodes or around the probe.

• Operating close (for example 1m) to short wave and microwave units or mobile
telephone systems can cause fluctuations in the output values of the electric current
stimulation unit.

• Do not use the machine during the simultaneous operation of other machines, when
driving or when asleep.

Contra indication

Please check with your physician before using the EMP 4 PRO if one of these
apply to you:

• Patients with electronic implants such as heart pacemakers, defibrillators or pumps

• Patients with cardiac rhythm disorders

• During pregnancy

schwa-medico EMP 4 PRO

4

• Patients subject to seizure disorder / epilepsy

• Patients with skin disorders in the vicinity of the electrodes

• Patients with malignant diseases in the region of application

Side effects

• Pain caused by the stimulation: The stimulation can be perceived as uncomfortable/
painful if the electric current is too intensive or if the electrodes have been positioned
unfavorably. Unpleasant side effects can be avoided by adjusting the intensity,
using another program with other parameters and the possible re-positioning of the
electrodes.

• Skin intolerance which can result from the electrodes, the electrode gel or the electric
current impulses. The physician should be consulted in cases of reddening, burning,
itching or blistering under the electrodes or in the vicinity of the electrodes. Slight skin
reddening of short duration in the area of the electrodes following stimulation is quite
normal because blood circulation has been improved by the effects of the stimulation.

• Muscular pain: If the stimulation has been too intense or too long muscular aches
in terms of sore muscle can occur. Shorten the treatment time and the intensity of
stimulation at the beginning of muscle stimulation to avoid muscle ache.

Setting of intensity levels

Do not try to achieve a higher and higher level of intensity. Set the intensity in such a way
that you get a comfortable feeling during the stimulation. Increase the intensity carefully
to a maximum tolerable and then reduce it slightly step by step to a comfortable level.
Note that the intensity settings change depending on the stimulation area and the time.
This is normal and can be explained as follows:

• Resistance of the skin:
Dry skin has a lower conductivity level than damp skin (due to sweating). The skin does

not show the same resistance to linear current on all parts of the body. For example,
the resistance level of horny skin can be twice that of the skin in the hollow of the
knee. The innervation differs greatly according to the area of the body. This results in a
difference of sensitivity.

• Volume of the muscle mass:
If you stimulate muscles with a high volume you will automatically need to set a higher

intensity than for the stimulation of small muscles.

schwa-medico EMP 4 PRO

21

• Muscle fatigue:
A tired muscle will only tolerate a lower intensity.

• Age of electrodes:
Self-adhesive electrodes do not last forever. You can use them up for up to 60

stimulation sessions. This depends on the quality of the electrodes but also on the
skin of the user. Old electrodes have a higher resistance and their conductivity levels
decline. It is important to replace electrodes regularly.

• Adaption to the current:
The nerves adapt rapidly to the current. It is normal to feel “less current” after a few minutes

of stimulation with specific parameters. In such a case feel free to increase the intensity in
order to get the best results.

• Frequency and pulse width:
Frequencies and pulse widths differ depending on the programs. There-fore the intensity

can not be set at the same level for all the programs even if the electrodes are placed in
the same position. The higher the frequency is set, the lower you will be able to set the
intensity.

The higher the pulse width is set, the lower you will be able to set the intensity.

Principle of dynamic stimulation

The stimulation is not administered simultaneously on all channels. The current flows from
one electrode to the other just like a wave undulating on the body. This kind of stimulation
is far more comfortable than traditional neuro-muscular stimulation.
Dynamic stimulation can be used with high frequency parameters for better pain control or
with low frequency parameters for optimized muscle stimulation. This treatment method
also has an enhanced effect on lymphatic drainage stimulation.

Positioning of the electrodes for dynamic stimulation

Sideways
Sideways movement:
E.g gluteus, stomach

Vertical movement
E.g. back, legs
Falling

In order to apply a falling wave, the channels must be
arranged as follows:
channel 1 (black)
channel 2 (red)
channel 3 (grey)
channel 4 (yellow)

Rising

In order to apply a rising wave, the channels must be
arranged as follows:
channel 4 (yellow)
channel 3 (grey)
channel 2 (red)
channel 1 (black)

Dynamic stimulation on legs:

Place one electrode of each channel on each leg (size 5x9 cm).

Dynamic stimulation on the back:

Place one electrode of each channel on each side of the spinal column
(size 5x9 cm).

Important note:

If you use electrodes with two connectors, always connect them to the same pole color of
the cables (either both white or both red).
