5 Introduction to Medium frequency Electro-Stimulation
General Notes Regarding Medium frequency Currents
The AmpliMove medical operates with rectangular impulses between 1000 and 10000
Hz – therefore in the electro-physical medium frequency range which is encompassed
between 1000 and 100000 Hz. This is quite different from the low frequency range
(1 - 1000 Hz), in which, for example transcutaneous electrical nerve stimulation, is
located (TENS).
A significant characteristic is the pleasing aspect of stimulation in the medium
frequency range. Higher frequencies overcome the resistance of the skin, in particular
that of the poorly conducting epidermis, much more efficiently. The 4000 Hz frequency
which is often used in medium frequency therapy must only overcome a resistance
of 40 Ohm; at 50 Hz it is 80 times higher. This enables an effective current flow at
reduced sensitivity unpleasantness. Powerful muscular contractions can be triggered
and a greater treatment area/treatment volume realized. Particularly electrical current
muscular stimulation profits from this effect. It is for this reason that it is a domain
for the medium frequency range. The AmpliMove medical provides the requirements
for a therapy which is efficient on account of its tolerability and its volume without
causing compliance problems which frequently occur in the low frequency range.
These advantages have an effect in pain therapy with the AmpliMove medical. There
arises one of the transcutaneous electrical nerve stimulation (TENS) comparable to
the analgetic effect which is attained via a low frequency modulation of the carrier
frequency. The positive characteristics of the medium frequency electro-stimulation
remain thereby preserved.
