Interferential current (IFC): This type of stimulation is characterized by the crossing of two electrical medium, independent frequencies that work together to effectively stimulate large impulse fibers. These frequencies interfere with the transmission of pain messages at the spinal cord level. Because of the frequency, the Interferential wave meets low impedance when crossing the skin to enter the underlying tissue. This deep tissue penetration can be adjusted to stimulate parasympathetic nerve fibers for increased blood flow. Interferential Stimulation differs from TENS because it allows a deeper penetration of the tissue with more comfort (compliance) and increased circulation.
Pre and post-orthopedic surgery, joint injury syndrome, cumulative trauma disorders, increasing circulation and pain control of various origins.
Interferential Therapy is used in the treatment of circulatory disorders, range of motion, edema and muscle spasms. Post-op patients will use the device 3 times a day for 15 minutes over a period of 14 - 30 days.
Since Interferential Therapy has been in use for many years, its effectiveness is well documented. Studies have shown that patients using Interferential Therapy after surgery develop fewer post-op complications than those relying solely on narcotics for pain relief. Interferential stimulation does not cause respiratory depression. Interferential Therapy aids in circulation, increasing the recovery time for patients. Multiple treatments at home or work will typically speed the patient's recovery and allow earlier resumption of their normal lifestyle.
Commonly Asked Questions in Regards to Interferential Therapy
Are Interferential devices safe?
YES. Although the thought of electrical impulses being sent into the body may seem frightening at first, all you really feel is a slight vibrating sensation. Unlike many drugs, Interferential devices have no known side effects.
Who cannot use an Interferential device?
Individuals with a pacemaker or patients who are pregnant should not use an Interferential device. Consult your doctor or clinician first.
Will an Interferential device work for me?
Interferential Therapy has been used extensively for managing post-surgical, post-traumatic acute pain, edema and inflammation reduction. It has been used successfully for a wide variety of procedures.
Does my insurance policy cover the cost of renting an Interferential device? Because Interferential Therapy is a proven method for pain, edema and inflammation reduction, most insurance carriers pay for the rental or purchase of the device.
Interferential current is essentially a deeper form of TENS. In essence, IFC modulates a high frequency (4000 Hz) carrier waveform with the same signal produced by a TENS unit. The high frequency carrier waveform penetrates the skin more deeply than a regular TENS unit, with less user discomfort for a given level of stimulation. Deep in the tissues, the carrier waveform is cancelled out, resulting in a TENS-like signal deep under the skin.
