In the four-pole method, the modulation depth is only 100% at the diagonals.
Vector techniques
Additional to the classical Interferential, 3 different dynamic Vector techniques have been developed, which all aim to
increase the treatment possibilities of 4-pole Interferential. The dynamic Vector techniques are used to increase the
effective stimulated area. Each Vector technique distinguishes itself with a specific vector field (Fig. 17 - 19).

The Vector techniques are not only used to increase the treatment area. The Vector techniques can also be used to
reduce the adaptation.
As already mentioned, the modulation depth is a criteria for the effectiveness of the electrical current and is
expressed in a percentage. The stimulation is optimal when the modulation depth is 100%.
With the graphic drawing of the different vectors it is so that, when a cross is shown between the electrodes (as
shown with Isoplanar vector, Fig. 23) there is an optimal stimulation in every direction. If a cross is shown, like with
classical Interferential (see picture 20), it means that there is only effective stimulation in two directions. The electrode
placement is in this case also very critical.
