Inferential Current Therapy (IFC) is characterized by

• A. Applying two separate medium frequency currents of different frequencies to the same area.
• B. Using a single low-frequency current.
• C. Heating tissue with a continuous current.
• D. Delivering ionized medication into tissue.

Answer: (A)

Inferential Current Therapy works by using two medium-frequency alternating currents that differ slightly in frequency and are applied to the same area. As they intersect in the tissues, they create an interference pattern, producing a beat frequency equal to the difference between the two frequencies. That low-frequency modulation reaches deeper tissues while the higher carrier frequencies pass through the skin with less impedance, making the therapy comfortable and enabling effects like pain relief and muscle relaxation. This is why applying two medium-frequency currents of different frequencies to the same area best describes IFC. The other options describe different modalities: a single low-frequency current isn’t IFC; heating tissue with a continuous current is a different approach (diathermy or galvanic heating); delivering ionized medication into tissue refers to iontophoresis.
