This technique is widely used to elicit muscle contraction, promote healing and reduce edema .
It is a type of electo therapy treatment that uses electric currents to stimulate tissue which provides pain relief, reduction of swelling and many other health benefits.
The principle of interferential therapy is to cause two medium frequency currents of slightly different frequencies to interfere with one another.
It is basically used for the treatment of Chronic, Post Traumatic, and Post-surgical pains.
IFT uses a range of frequencies that stimulate the body to get positive reactions such as increasing the blood supply in an area which in turn increases the healing speed.
The major advantage of IFT is that it produces effects in the tissue, exactly where required without unnecessary and uncomfortable skin stimulation.
This technique is widely used to elicit muscle contraction, promote healing and reduce edema .
IFT is the form of the electrical treatment in which two medium frequency currents are used to produce a low – frequency effect .
How to work of Interferential therapy?
Interferential current therapy works by sending small amounts of electrical stimulation to damaged tissues in the body.
The therapy is meant to boost the body’s natural process of responding to pain, by increasing circulation thus produces hormones that promote healing.
IFT delivers intermittent pulses to stimulate surface nerves and block the pain signal, by delivering continuous deep stimulation into the affected tissue.
A frequency of 100Hz may stimulate the large diameter A-beta fibers, which have an effect on the pain gate, and inhibit the transmission of small-diameter nociceptive traffic ( C and A-delta fiber), which effectively closes the gait to painful impulses.
Interferential current Increases the circulation of blood thus reduces swelling, by washing away the chemicals that stimulate the nociceptive nerve endings.
