Interference therapy
Medical expert of the article
Last reviewed: 07.07.2025
Interference therapy is a method of local action with two alternating sinusoidal electric currents of corresponding parameters through two pairs of electrodes and wet hydrophilic pads, contacted on certain areas of the patient's skin in such a way that these currents intersect (overlap) and interact with each other in a certain place in the body tissues.
Current strength up to 50 mA; current oscillation frequency within 3000-5000 Hz; the frequency of one current is constant, the other differs by 1-200 Hz.
Interference therapy is based on the action of interference (superposition) of two electromagnetic oscillations of the same amplitude and close frequency and the occurrence in tissues of an interference current with a doubled amplitude of oscillations of the original currents with low-frequency amplitude modulation. Physicochemical reactions are associated with the features of electrodynamic changes in the structures and systems of the body from the effect of the interference current, and subsequent biological processes are caused by conformational rearrangements based on these features.
The main clinical effects of interference therapy are: analgesic, myoneurostimulating, trophic, antispasmodic, and defibrosing.
Equipment: “AIT-50-2”, “Interdin”, “Interdynamic”, “Interference-IFM”, etc.
