Low and medium Frequency Electrotherapy - Implox

The formula given above is for uninterrupted direct current. The dosage with medium-frequency direct current can be
somewhat higher, as the current is milder with less chance of skin erosion. Nevertheless, these guidelines should still
be maintained, particularly where sedative medication is applied, as the resulting loss of sensitivity will eliminate the
signalling function of pain. Similar considerations apply with substances that affect the total system (e.g. histamine).
7.3 Variations on a theme
Interruption of the direct current with a frequency of 8000 Hz offers more applicational possibilities than one would, in
the first instance, expect.
In addition to iontophoresis, the medium-frequency direct current can be used for the treatment of neuralgia by
transverse galvanization, as described by Kowarschik, as well as for such applications as the treatment of excessive
perspiration in the hands and feet (25) , improvement of the peripheral circulation, wound healing and the treatment of
hyperalgesic zones on the skin.
An explanation of the effects in these indications can be found in the influence on the sympathetic nervous system
(see Chapter 10: Examples of Treatment).
