Interferential Current Therapy
Interferential Current (IFC) is a common modality used in treatment. The primary focus of IFC is to provide a localized temporary pain control and consists of the placement of 4 electrodes placed around or near the pain site. An electrical impulse is passed through the involved area which is perceived by the brain as a tingling sensation.
This tingling sensation interferes with the pain pathway that has been experienced by the same portion of the brain thus minimizing or diminishing the pain impulse. Physiologically at the site of the IFC there is a localized increase in blood flow which helps to enhance healing.
