Interferential Current (IFC) is a trusted, clinically-proven, noninvasive therapy used for the management of, and
relief from, chronic (long-term) intractable pain and post-surgical and
post-trauma acute pain.
- It is an effective and safe alternative to prescription, pain control
medication with NO known side-effects or risk of overdose.
- IFC decreases pain and helps the patient remain
functional and productive.
- It is easy to administer, typically reimbursed, and
cost effective - by often reducing the need for PT or OT services.
- IFC allows for patient control over pain management.
Interferential Current therapy utilizes two medium frequency
currents passed through the tissues simultaneously. The currents are
designed to cross and literally interfere with each other, giving rise to
an interference (beat frequency) which mimics low frequency stimulation.
The resultant beat frequency can be controlled by input frequencies (e.g.,
4000Hz current interferes with 3900Hz companion current to result in a
beat frequency of 100Hz, carried on a medium frequency 3950Hz amplitude
modulated current).
When an interferential current is applied to skin, skin impedance
decreases as pulse frequency increases - making the stimulation more
comfortable. IFC is capable of reaching greater depths over a larger
volume of muscle tissue - making it ideal for deep pain.
- Relief of chronic (long-term)
intractable pain
- Reduce Muscle Guarding
- Relief of post-surgical acute pain
- Relief of post-trauma acute pain
- Management of acute and chronic edema
- Increases local blood flow
- Can affect the operation of demand
type cardiac pacemakers
- Not recommended for patients with known heart disease
without physical evaluation of risk
- Do NOT Apply over the
anterior aspect of the neck or carotid sinus
- Do not apply IFC for undiagnosed pain syndromes until
etiology is established
-
Electrodes should not be placed over the eyes
- Avoid active epiphyseal
regions in children
- Use of abdominal
electrodes during labor may interfere with fetal monitoring equipment
- Turn the stimulator off before applying or removing
electrodes
- Electrotherapy may cause skin irritation
beneath the electrodes
