Phase Duration
, expressed in ms or s, is the elapsed time from the beginning to the end of the pulse
phase. See fig 4.1.4.5.2 and 4.1.4.5.3 for details.
Pulse Frequency
, expressed in Hz or pps (pulses per second), defines the repetition rate of the current
pulses. See fig 4.1.4.5.2 and 4.1.4.5.3 for details.
Surge Program
can be used to adjust repeated sequences of contraction and rest periods. See
paragraph 8.2.5.6 for details.
4.1.3.9.2 Träbert, 2 – 5 Current
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 2ms and a phase
interval of 5ms. 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. A remarkable effect is that patienst are free from pain which can appear from just the first
treatment and which can last for several hours. See fig 4.1.4.5.1 for a graphical representation.

CAUTION:
•
Faradic currents are monophasic currents that produce electrolysis by-products. These by-
products can result in burns beneath the electrodes. Always use properly moistened sponge /
electrode combinations to absorb these by-products during treatment. See paragraph 7.1.5 for
details.
Parameters:
Phase Duration
, expressed in ms or s, is the elapsed time from the beginning to the end of the pulse
phase. The default setting is 2ms. See fig 4.1.4.5.1 for details.
Phase Interval
, expressed in ms or s, is the elapsed time between successive pulse phases. The default
setting is 5ms. See fig 4.1.4.5.1 for details.
