Interference current/IFT/ is a current obtained on the principle of wave interference, in which a third low-frequency current is obtained from two medium-frequency currents, which is the difference in frequency between the two. Thus, at the frequency of one 4000Hz, and the second from 4001 to 4100Hz, a third is obtained in depth in the tissues with a frequency equal to the difference - from 1 to 100Hz. It is this current that has a therapeutic effect. This method of electrotherapy is similar to the therapy with low-frequency currents, but its disadvantages are avoided - little penetration in depth, irritation and pain at a relatively small current strength. Interfering current sensations are deep frequency-varying vibrations and a prickling ("pins and needles") sensation as a result of the current. The therapeutic effects of the use of interference current are related to its physiological action on the body. Depending on the frequency, it can generally be said that low frequencies up to 50Hz have a stimulating effect on the muscles, and from 50-100Hz are associated with an analgesic effect. The interfering current causes an improvement in peripheral blood circulation, tissue metabolism and the release of biologically active substances (acetylcholine, histamine), which creates conditions for: anti-edematous anti-inflammatory analgesic effect callus-forming/ accelerates bone healing/ physiological effect: acceleration of the healing process due to an increase in blood flow and the permeability of cell membranes, reduction of pain as a result of blocking pain receptors (gate theory) and the release of endorphins, reduction of the tone of spastic muscles and edema in traumas, Accelerates the healing of bones in case of fractures.
