Interferential 520B is a medium frequency unit that is controlled by microprocessors. It is equipped with a liquid crystal display (LCD) as well as two channels. The touch control switches & the LCD allow quick & precise selection of parameters which are then clearly displayed on LCD. The therapist gets easily familiar with the controls & will enjoy simple application of the unit in treatment..


Unique features

Interferential 520B unit, like all other inferential units comes in two- and four-electrode models as well as a four-electrode model that can be used in conjunction with a vector scan. Yet it is distinguished by its auite specified currents: Isoplanar vector field, Dipole vector field and Russian stimulation.
 

Classic IF

As shown in figures of page 20 of Principles and Applications of Interferential There will be no modulated current over the’ axis of four electrodes joint; %100 percents of modulated interferential current would be applied in 450 angle of this axis.
 

Isoplanar vector field

Unlike traditional and old inferential currents in which the AMF distribution was unevenly emitted between the electrodes, Interferential current would be distributed evenly over all the tissues under the electrodes, with 100% modulation. Consequently exact positioning of the electrode would not be necessary. This current is applied where the treatment area is wider or where the treatment area is not quite localized. This type of current is also recommended in acute pains. It is considered to be the most pleasing type of current.


Dipole vector field

In this method, 100% modulation is linearly applied. The significant advantage of this type of current is that the direction of current can be either selectively determined, or the linear current be automatically moved round a complete circle. The latter method is recommended in the treatment of muscular spasms, and the selective method in case of long tissues such as the sciatic nerves.



Russian stimulation

Research has shown that the use of the 2500 Hz frequency is much more convenient and effective than the Surge Faradic method using low frequencies for muscle contraction. This type of current is particularly useful in the convalescence period after an operation, when the patient is forbidden to move to prevent Disuse atrophy and also when the muscle is painful.


50 saved and 50 adjustable programs

Interferential 520B is prepared with 50 saved programs which cover the entire range of common inferential treatments. Yet, the therapist would still enjoy the possibility to arrange and save his or her own desirable program for later use as required.


 

The book "Principles and Applications of Inferential"

New discussions regarding inferential, its application and contradictions as well as the treatment methods are discussed in detail. One volume of the book accompanies each unit of Interferential 520B.
