IFC

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.

Benefits of IFC

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.

Mechanism of actions for IFC

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.

Indications for IFC

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.

Contraindications for IFC

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.

Precautions

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.
