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).
Read moreWhat is medium frequency currents?
MEDIUM-FREQUENCY alternating currents (MFACs), defined as currents in the frequency range 1 to 10kHz , are used extensively in rehabilitation.
Read moreWhich of the following is the physiological effects of IFT?
As IFT acts primarily on the excitable (nerve) tissues, the strongest effects are likely to be those which are a direct result of such stimulation (i.e. pain relief and muscle stimulation ). The other effects are more likely to be secondary consequences of these.
Read moreWhat are high frequency currents?
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.

There were also elevations in the levels of plasma serotonin, beta endorphin, GABA and DHEA together with diminished levels of cortisol and tryptophan. Concomitant with these changes were significant improvements in the symptoms of pain, insomnia, spasticity, depression, and headache .
Read moreWhat is medium frequency current in physiotherapy?
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.
Read moreWhat is medium frequency electrotherapy?
Interferential therapy involves the use of “medium frequency” current to bring about the effect of a low-frequency (LF) current in the tissues . This is achieved by applying two “medium frequency” currents to the tissues, to generate LF interference current.
