Abbreviation for interferential current.
A form of electrotherapy in which a current having specific properties is used to alleviate pain or facilitate healing in deep body tissues. The current used in IFC is produced by the interference of two medium-frequency (kiloHertz) sinusoidal alternating currents of slightly different frequencies. The nature of this interference creates an amplitude-modulated current that can be adjusted to produce various physiological effects.
