5 Current
Faradic currents are monophasic currents that produce electrolysis by-products. These by-
products can result in etching beneath the electrodes. Always use properly moistened sponge /
electrode combinations to absorb these by-products during treatment.
The 2-
5 or ‘Ultra
-
Reiz’ current was introduced by Träbert
(*). It is often used to treat headaches and
neck pain. The 2-5 current is a faradic rectangular pulsed current with a phase duration of 2
milliseconds and a phase interval of 5 milliseconds. These settings are the default settings for the
faradic rectangular current waveform and result in a pulse frequency of approximately 143 Hz. Träbert
offered no explanation for the choice of these parameters. Nevertheless, many specialists have
adopted the therapy and it is still applied with success.

Parameters:
•
Phase Duration,
expressed in milliseconds or seconds, is the elapsed time from the beginning to
the end of the pulse phase. The default setting is 2 milliseconds.
•
Phase Interval,
expressed in milliseconds or seconds, is the elapsed time between successive
pulse phases. The default setting is 5 milliseconds.
