The are 5 main clinical uses for which IF appears to be beneficial: 1- Relief and management of acute and chronic pain. 2- Muscle stimulation. 3- Increased blood flow. 4- Reduction of edema. 5- Stimulating of soft tissues healing and repair.

What is interferential current therapy (IFC)?

Interferential current therapy is an effective therapy option used to relieve pain and accelerate the self-healing process, getting your body back to a healthy, pain free state. The high frequency signals of an IFC penetrate through the skin into deeper lying muscle tissues.

How does IFC work?

Electrodes are placed on your skin around the injured body part. The Interferential Current device then transmits electrical impulses in minute quantities through your skin. Underlying tissue and nerves are stimulated which begins the healing properties.

How does IFC feel?

These impulses are not painful in the least. In fact, patients describe the sensation as a minor prickle on their skin.

Benefits of IFC

Frequencies produced by the IFC have been proven to stimulate endorphins, the body’s natural pain killers. This can help to create a self-healing process without the need to for medications. This form of therapy is also extremely useful in reducing pain, inflammation, edema, and spasms. – Reduces or eliminates your pain safely. – Noticeable decrease in swelling and inflammation. – Restores lost movement and improves restricted movements and coordination. – Stimulates the natural hormones which can help your body heal faster. – Considered by many experts as a highly effective form of treatment for chronic pain.

Is IFC safe?

Absolutely! The electrical impulses sent through your body are tiny. You will not experience any pain or shock. At the most, you will experience a slight tickling sensation.


Interferential current therapy is a deeper form of the common treatment TENS. The frequency is higher at 4000Hz from interferential current therapy compared to the same signal released by a TENS unit at low frequencies of 5-160 Hz per second. The IFC’s high frequency waveform reaches the skin deeply with a higher level of stimulation and less discomfort to the patient.
