Abstract— Electrotherapy is drug free, non-invasive and non-addictive physiotherapy treatment. This treatment provides minimal risk and side effects and complications which are due to adverse drug. It also offers several advantages over old or conventional medical treatments for pain. A number of electrotherapy modalities were developed to offer the safest lifelong solutions. Interferential therapy (IFT) is one of the best electrotherapy modality. Working principle of IFT is based on the significant physiological effects of low frequency (< 250 Hz) electrical stimulation of nerves. IFT utilizes medium frequency stimulation to produce the strong physiological effects of low frequency electrical stimulation, in much deeper muscle and nerve tissues. Without the associated painful and unpleasant sensation of low frequency stimulation. Interferential signal used for stimulation is concentrated at the point of intersection between the electrodes. This concentration occurs deep in the tissues Thus, with Interferential Stimulators, current perfuse to greater depths and over a larger volume of tissue than other forms of electrical therapy. Thus, Interferential current penetrate into the skin without painful and unpleasant sensation allowing greater patient comfort during electrical stimulation.

In electrotherapy generally low frequency with sufficient intensity is used for muscle stimulation. But the main problem associated with the application of low frequency current to patients is the very high skin impedance, because skin impedance Z=1/2∏ FC, here F is frequency. Using high frequency current will reduce the impedance and hence reduce the discomfort that is used by low frequency currents. Interferential current (IFC) uses medium frequency signal to reduce skin impedance and discomfort and produces low frequency stimulation effects in deeper tissues of the body.
