Advice on size and type of electrodes to be used is given in device GUI treatment guidelines.
CC: Constant Curent CV: Constant Voltage
IFC (Interferential) Traditional (4 Pole)
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.

WAVEFORMS (CONTINUED)
VMS™ FR
The VMS-FR version of the VMS waveform is a physiologically based channel
interaction in which one channel stimulates the agonist and the other the
antagonist of the muscle group that is being exercised. The agonistic channel
initiates the movement with a brief burst of power, followed by a period of
sustained activity to complete the movement. The antagonistic channel has a
brief burst of power to slow down the initial acceleration of the agonist,
followed by a low output to regulate the movement of the agonist. The
movement is completed by a final burst of activity in both channels. VMS is a
symmetrical biphasic waveform with a 100 μsec interphase interval.
Because the pulse is relatively short, the waveform has a low skin load,
making it suitable for applications requiring high intensities, such as in
muscle strengthening protocols.
Output Mode Electrodes

High Voltage Pulsed Current (HVPC)
The High Voltage Pulsed Current (HVPC) has a very brief pulse duration
characterized by two distinct peaks delivered at high voltage. The waveform
is monophasic (current flows in one direction only). The high voltage causes
a decreased skin resistance making the current comfortable and easy to
tolerate.
