The interference field can be rotated which allows a greater volume of tissue to be treated. IFT penetrates to deep tissue without causing any discomfort to the skin surface due to the decreased skin resistance afforded by medium frequency currents. IFT can be used for pain control. The Neural fibers are stimulated in the tissue where the maximum interference occurs and the two currents cross. The target area can be large or small and the currents can be controlled to the specific area of the Injury. It reduces Oedema & Hematoma reduction. Rhythmic frequencies help in the absorption of exudate through pumping action at injured area.
