INTERFERENTIAL CURRENT (IFC) ELECTRICAL STIMULATION:
Interferential therapy is superior to other modalities for treating musculoskeletal and deep joint complaints. These joints include those of the shoulder, elbow, hip, knee, ankle, and spine. Unlike other forms of stimulation that produce effects from the outside to the inside of a body part, IFC consists of 2 medium frequency currents that cross deep within a body part which then triggers the formation of a third current that radiates from the inside to the outside. This means that the therapeutic effects are concentrated below the surface of the skin without being scattered by skin resistance. IFC is used in the locker rooms of all professional athletes.
