EXPLANATION OF IF
Interferential Stimulation (IF) is an anti-inflammatory based treatment
modality. Interferential stimulation is characterized by two
alternating-current sine waves or square waves of differing
frequencies that “work” together to produce an interferential current
that is also known as a beat pulse or alternating modulation
frequency. One of the two currents is usually held at 4,000 Hz, and
the other can be held constant or varied over a range of 4,001 to
4,100 Hz. Because of the frequency, the interferential wave meets
low impedance when crossing the skin to enter deep into soft tissues.
The interferential currents reportedly can stimulate sensory, motor,
and pain fibers. These large impulse fibers interfere with the
transmission of pain messages at the spinal cord level. This deep
tissue penetration stimulates parasympathetic nerve fibers for
increased blood flow and edema reduction. It utilizes the low electric-
current to stimulate muscle nerves to achieve the symptomatic relief
of chronic intractable pain, post-traumatic pain, and post-surgical
pain.
1.3 Indication for use

T M
IF Combo Stimulator may be used for the Symptomatic
relief of chronic intractable pain, acute post traumatic pain or acute

IMPORTANT SAFETY INFORMATION!
Read instruction manual before operation. Be sure to comply with all
“Contraindications”, Warnings”, “Cautions” and “Adverse reactions”
in the manual. Failure to follow instructions can cause harm to user
or device.
1.4 Contraindications
1
This device should not be used for symptomatic local pain relief
unless etiology is established or unless a pain syndrome has
been diagnosed.
this stimulation will greatly reduce or eliminate the pain sensation the
patient feels. Pain relief varies by individual patient, mode selected for
therapy, and the type of pain. In many patients, the reduction or
elimination of pain lasts longer than the actual period of stimulation
(sometimes as much as three to four times longer). In others, pain is
only modified while stimulation actually occurs. You may discuss this
with your physician or therapist.
