Two medium frequency currents are used to produce the interferential current. They are known as carrier waves as they don't produce muscle or nerve stimulation and are used just used to get the greater depth of penetration and to produce interferential current.
Interferential therapy involves the use of “medium frequency” current to bring about the effect of a low-frequency (LF) current in the tissues. This is achieved by applying two “medium frequency” currents to the tissues, to generate LF interference current.

Jan 17, 2022 · For example, one of the alternating currents may be a fixed frequency at 4000 Hz, while the frequency of the other alternating current can be set between 4000 and 4250 Hz. The two medium-frequency currents “interfere” within the tissues and produce an amplitude-modulated low “beat” frequency (0–250 Hz), which is the difference between ...

The exact frequency of the resultant beat frequency can be controlled by the input frequencies. If for example, one current was at 4000Hz and its companion current at 3900Hz, the resultant beat frequency would be at 100Hz, carried on a medium frequency 3950Hz amplitude modulated current.

What happens if two medium-frequency currents interfere?
When interferential therapy is applied in electrotherapy, use is made of two medium-frequency alternating currents that interact with each other. One of these alternating currents has a fixed frequency of 4000 Hz, while the frequency of the other current can be adjusted between 4000 and 4250 Hz.

Dec 14, 2021 · Abstract. Background and Objectives: Transcutaneous electrical stimulation of low- and medium-frequency currents is commonly used in pain management. Interferential current (IFC) therapy, a medium frequency alternating current therapy that reportedly reduces skin impedance, can reach deeper tissues.
