Interferential current (IFT) is a physical
modality that is typically used to help relieve pain over a specific area of
the body.
The IFT machine produces an electrical
current that stimulates the nervous system to interrupt the pain signals felt
by the brain. The low frequency electrical stimulation of IFC crosses the skin
with greater ease, and is generally more comfortable and better tolerated by
patients.
It also allows to stimulate deeper tissue, increase blood flow in the area and even
reduce the effects of edema which causes swelling.
