Interferential therapy (IFT) is a popular electrotherapeutic modality for pain management. It is characterized by the interference of 2 medium-frequency currents (ie, 1–10 kHz ), which combine to produce a new medium-frequency current whose amplitude is modulated at low frequency (ie, <1 kHz).

Medium frequency currents are the currents whose frequency falls between the range of 1000 to 10,000 Hz . They are being used therapeutically due to their advantage of greater penetration and with a higher tolerance and comfort over the low frequency current.

(hī-frē’kwĕn-sē kŭr’ĕnt) An alternating electric current having a frequency of 10,000 or more cycles per second ; it produces no muscular contractions and does not affect the sensory nerves.
