Interferential Therapy Machine (Eco Models)
The basic principle of electrotherapy Interferential Therapy (IFT) is to utilise the strong physiological portable interferential effects of low frequency (<250pps) electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low frequency stem.
To produce low frequency effects at sufficient intensity at depth, patients can experience considerable discomfort in the superficial tissues (i.e. the skin). This is due to the impedance of the skin being inversely proportional to the frequency of the stimulation. In other words, the lower the stimulation frequency, the greater the impedance to the passage of the current & so, more discomfort is experienced as the current is ‘pushed’ into the tissues against this barrier. The skin impedance at 50Hz is approximately 3200* whilst at 4000Hz it is reduced to approximately 40*. The result of interferential machines applying a higher frequency is that it will pass more easily through the skin, requiring less electrical energy input to reach the deeper tissues & giving rise to less discomfort.
Application
The clinical application of IFT therapy is based on peripheral nerve stimulation (pps) data, though it is important to note that much of this information has been generated from research with other equipment, and its transfer to IFT is assumed rather than proven. There is a lack of Interferential Therapy specific research compared with other modalities (e.g. TENS).
