ABOUT CEFAR
CEFAR Medical has conducted research and product development in electrical nerve
and muscle stimulation since its establishment in 1975, and is globally represented
through a network of subsidiaries and distributors.
CEFAR’s stimulators are used for TENS, NMES, electroacupuncture and iontophoresis
and send electrical impulses via electrodes placed on a chosen body part. Electrical
nerve and muscle stimulation has no side effects.

References
The areas of application for electrical nerve and muscle stimulation within the medical
 eld are developed through clinical research.
Electrical nerve and muscle stimulation as an active method for training and
recovery is further developed through a close cooperation with medical experts and
top athletes.

IFC does – creates a larger treatment
area, since the interference current is
not constant but scans, or rotates, over
a larger area (40% scan ≈ 45 degrees’
rotation); see illustration 2.
1. Quadripolar application.
2. Quadripolar application with vector scan.
Bipolar application, commonly called
premodulated (Programs 4–6 in the
CEFAR IFC), uses only two electrodes.
The current is not modulated in the
tissue, but in the stimulator, so it is
already modulated when it reaches the
electrodes. The treatment field should
be between the two electrodes.
The basic idea of interference is that
you use two different mid-frequency
alternating currents (1,001–10,000 Hz)
in the treatment area. Where the two
mid-frequency currents meet, a current
is created that has a lower frequency
(1–1,000 Hz) or beats per second
(bps). The advantage of mid-frequency
currents is that they pass through the
tissue more easily and deeply than low-
frequency current, which gives somato-
sensory and motor nerve stimulation.
By blocking pain impulses (the Gate
Control theory) and releasing endorphins,
interference currents ease both acute
and long-term pain conditions.
Interference can also be used to gene-
rate muscle contractions, which can be
used for training the perineal muscles
and reducing edemas.
Interference can be applied to the tissue
in two ways, quadripolar or bipolar.
Quadripolar application (programs 1–3
in the CEFAR IFC) requires four elec-
trodes placed so that the current meets
in the treatment area. Where the cur-
rent meets, a current field is created in
a four-leaf clover shape; see illustration
1. The frequency in the treatment field
can be constant or modulated. The aim
of modulation is to avoid nerve adapta-
tion and to enhance comfort for the
user. Adding a vector scan to the quad-
ripolar method – which the CEFAR

The CEFAR IFC is a two-channel
interference stimulator with 6 preset
programs. P1–3 are interference stimu-
lation (80–150 Hz) with simultaneous
channels. Interference is ideal for reliev-
ing pain over large areas of the body.
P4–6 are premodulated interference sti-
mulation with separate channels, which
is better for smaller areas or for treating
two different areas at once. P7 is an
open program for your own settings.
The CEFAR IFC has a keylock that
prevents unintentional changes in
amplitude. The keylock is activated 20
seconds after the amplitude is set.
You can pause stimulation by reducing
the amplitude to 0. When you increase
the amplitude again, the program
picks up where it left off. Note: If the
stimulator is paused for more than five
minutes, it switches off automatically to
spare the batteries.
The CEFAR IFC runs on 1.5 V AA bat-
teries, rechargeable or non-rechargeable.
A battery indicator on the stimulator’s
display lights when it is time to change
or charge the batteries. The CEFAR
IFC can also run on current from a wall
outlet via an adapter.
