Interferential Therapy (IFT) is a treatment that utilizes two sets of electrical currents with different frequencies to stimulate nerve activity and create a vibration effect that helps relax tense muscles. The therapy involves the use of four circular electrodes, with their placement, frequency, and patterns determined based on the patient’s specific symptoms. This method primarily alleviates pain at the injury site, accelerates blood circulation, and facilitates the removal of metabolic waste.
