What type of current is interferential current?

Interferential current therapy (IFC) is based on summation of 2 alternating current signals of slightly different frequency . The resultant current consists of a cyclical modulation of amplitude, based on the difference in frequency between the 2 signals.

The basic principle of Interferential Therapy (IFT) is to utilise the significant physiological effects of low frequency (≅<250pps) electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low frequency stimulation .

[1] In this review we would mainly focus on Transcutaneous Electrical Nerve Stimulation (TENS) and interferential therapy (IFT) which use low- and medium-frequency currents , respectively for pain relief.

Interferential current stimulation (IFS) is a type of electrical stimulation that uses paired electrodes of 2 independent circuits carrying high-frequency (4,000 Hz) and medium-frequency (150 Hz) alternating currents.

Interferential current therapy (ICT, or sometimes IFC) is the most common type of electrical muscle stimulation used to treat chronic pain resulting from surgery, injury or trauma . The end goal for using ICT as part of a physical therapy or rehab program is to relieve pain and help patients heal faster.

IFT which stands for Interferential Therapy is one of the types of electrotherapy used for the management of pain. The principle of interferential therapy is to cause two medium frequency currents of slightly different frequencies to interfere with one another.31 Mar 2020
