WAVEFORMS
IFC (Interferential) Traditional (4Pole)
Advice on size and type of electrodes to be used is given in
device GUI "treatment guidelines" feature
Interferential Current is a medium frequency waveform.
Current is distributed through two channels (four
electrodes). The currents cross each other in the body at
the area requiring treatment. The two currents interfere
with each other at this crossing point, resulting in a
modulation of the intensity (the current intensity increases
and decreases at a regular frequency).

The Asymmetrical Biphasic waveform has a short pulse
duration. It is capable of strong stimulation of the nerve
fibers in the skin as well as of muscle tissue. This waveform
is often used in TENS devices.Because of its short pulse,
the patient typically tolerates the current well, even at
relatively high intensities.
