Interferential Therapy

Application of two medium currents produces a low-frequency current effect at the point of intersection of the two currents. This is the basic principle of the Interferential Therapy. Interferential Therapy(Current) is the application of electrical energy to the tissue in which two medium frequency alternating currents of around 4000 Hz, slightly out of phase, produce an Amplitude Modulated current of low frequency through the effect of interference.

Interferential Therapy

Application of two medium currents produces a low-frequency current effect at the point of intersection of the two currents. This is the basic principle of the Interferential Therapy. Interferential Therapy(Current)  is the application of electrical energy to the tissue in which two medium frequency alternating currents of around 4000 Hz, slightly out of phase, produce an Amplitude Modulated current of low frequency through the effect of interference.

In the interferential Therapy, we make use of two medium frequency alternatively currents. These medium frequency currents are not identical and may differ in frequency up to 150 Hz. Two oscillators of medium frequency are generated and are cross wisely applied to the body by means of four electrode pads.(CH1) & (CH2) Each channel with one pair of pads i.e. two No. of pads. One oscillator has a fixed frequency of 4000 Hz the other can be ranged in the freq. between 3850 Hz. Both oscillators interfere i.e. intersect inside the body resulting in a modulated signal as a carrier and low-frequency part (The difference in frequency)for the actual therapy. In simple words, we can define the interferential therapy as when two medium frequency currents, i.e. CH1 &CH2 intersects with each other, leading interference currents to be generated at the place. For example, let us take two medium frequency current, Current in CH1 =4000Hz.&CH2=3850Hz.

These two currents are applied to any part of the body (or a tissue) at the points where the currents cross each other. The new Beat frequency current set up is amplified which is been modulated i.e. AMF Amplified modulated medium frequency and the frequencies of the new currents are called interferential current which is 150Hz) by varying the constant frequency of the first it is possible to create any desired frequency rate in the carrier currents.

Uses of Interferential Therapy

The following conditions have been reported to be effectively treated by interferential Therapy either alone or in combination with other therapeutical methods.
Pain Muscle Spasm: It is effective in relieving the pain of neurogenic nature such as post-herpetic neuralgia causalgia, Phantom limb pain, shoulder hand syndrome, musculotendinous, ligamentous and skeletal disorders etc.
