IFT which stands for Interferential Therapy is one of the types of electrotherapy used for the management of pain. It is basically used for the treatment of Chronic, Post Traumatic, and Post surgical pains. The basic principle involves the utilization of effects of low frequencies (<250pps) without painful or unpleasant side effects. IT involves the production of Interferential frequency by the interaction of 2 different frequencies. Major advantage of IFT is that it produces effects in the tissue, exactly where required without unnecessary and uncomfortable skin stimulation.
This technique is widely used for to elicit the muscle contraction, promote healing and reduce Oedema.
