3. IFC FF-Full Field Mode:
The well-known attributes of modulated medium
frequency currents, i.e. deep tissue penetration,
asynchronous neural stimulation, and low tissue
resistance, allows the creation of an interferential
therapy system capable of both deep and
superficial stimulation with the goals of
maximizing sensory inputs. This technique is
referred to as full field interferential current
therapy. Full field amplitude summation
interferential current therapy relies on the
addition and subtraction of two intersecting
currents within the tissue. This effect is based on
the relative phase differences between the
currents at different positions in the field. The
following technique is used in the
OMNISTIM
®
500 when in the full field mode of operation.
The highest intensity field is obtained in the deep
tissue at bisecting angles to the out-of-phase
electrodes. This technique offers three
stimulation fields.
Amplitude Summation - IFC Technique
Should the clinician desire rapid analgesia and maximum comfort in both the surface and deep tissues, continuous
non-modulated MF currents may be used with the
OMNISTIM
®
, which will produce strong nerve blocks
(Wedensky Inhibition) throughout the entire treatment field. This is often useful in the mobilization of joints, prior
to transverse friction massage, or for relieving acute pain. It should be noted that this technique would produce only
transient relief of pain.
The effects of full field interferential current
therapy may be described as follows:
a.
Stimulation of deep and surface
tissues.
b.
May be used to produce deep and
surface analgesia via nerve block
(Wedensky Inhibition) when MF
mode is used.

Treatment Programs
The IFC mode contains five pre-programmed
modes and a custom program, which may be
programmed and saved by the user. The
custom program will remain as long as the
batteries remain charged or are not removed.
All parameters other than the Carrier frequency
may be varied during operation. The following
programs are available in IFC mode:
RATE SCAN ON OR OFF
2500 or 5000 Hz Pulsed at 100Hz
2500 or 5000 Hz
