(IFC) (in'tĕr-fĕr-en'shăl kŭr'rĕnt)
An electrotherapeutic modality that employs the interference of two medium-frequency polyphasic sine waves to produce a low-frequency modulated sine wave over the area of treatment.

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.
