Electrode placement

The placement of electrodes is one of the most important parameters in achiev�

ing eective pain relief using TENS. This is best left to your Physiotherapist or

Physician to advise as to which location is most appropriate.

Quadripolar orientation of electordes for IFC stimulation.

True interferential stimulation requires the use of four electrodes placed on the

body as described in the diagram below. Each pair of electrodes creates a current

ow between them. When two pairs of electrodes are used, the current ows

intersect within the tissue. By making the frequencies for the two channels of

stimulation slightly dierent, an interference or “beat” frequency is established

at the point of intersection. This “quadrapolar” interferential eect provides a

greater amount of stimulation deeper within the tissue than non�interferential

modes of electrotherapy.
