Interferential therapy is based on the effect of low frequency stimulation as in the biological frequency range. The low interferential current is the result of two interacting medium frequency current produced by IF units. Interferential stimulator means the transmission of a small electrical pulse through the skin into painful area causing a mild tingling sensation. This sensation works to prevent pain signals from reaching the brain. IF uses four electrodes which allow better focus and deeper tissue stimulation.

• IF: Interferential Stimulator.
• Principle: Transmission of a small electrical pulse through the skin into painful area causing a mild tingling sensation.
• Application: Symptomatic relief and management of chronic intractable pain. Adjunctive treatment in the management of post surgical and post traumatic acute problems. Soft tissue of the forefoot.
