Interferential current, or IFC, is the electrical stimulation of soft tissues. It is similar to transcutaneous electrical nerve stimulation (TENS), only with higher frequencies.
Interferential current therapy delivers controlled electrical impulses through the skin to the underlying tissues.
Using higher frequencies than TENS, IFC penetrates deeper into the soft tissue. Higher frequencies are also more comfortable than the lower frequencies of TENS.
In an IFC treatment, strategically placed electrodes send high-frequency electrical pulses through the skin into the underlying tissue. The current stimulates the muscles, causing them to relax. Tension and inflammation subside, relieving pain. Blood flow to the area increases, speeding healing.
As part of a rehabilitation program, interferential current treatments help return muscles and joints to normal function.
Inferential current therapy is completely safe and relatively painless. It can be used to treat both acute injuries and chronic pain.
It’s not for everyone, though. Only a complete assessment with a certified therapist can determine whether IFC is an effective addition to your treatment plan.
