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.

Interferential therapy can relieve pain, reduce swelling, activate cell function and promote healing, therefore restoring function. Because of its versatility and effectiveness, Interferential is often choice for the treatment of physical condition such as Rheumatism, Arthritis, Muscle Strains, Spor...
