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.
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. Therefore the intensity cannot be set at
the same lever 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.
