Electrode placement
The placement of electrodes is one of the most important parameters in achiev�
ing effective 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
flow between them. When two pairs of electrodes are used, the current flows
intersect within the tissue. By making the frequencies for the two channels of
stimulation slightly different, an interference or “beat” frequency is established
at the point of intersection. This “quadrapolar” interferential effect provides a
greater amount of stimulation deeper within the tissue than non�interferential
modes of electrotherapy.
