Professional. Monopolar, Bipolar and Quadripolar techniques are illustrated. Electrode placement is dependent
on the etiology of the condition.
Monopolar (Mono-Polar) Technique
This technique may use two electrodes of different sizes. The smaller or
“active” electrode can be positioned over the segmental innervation or
peripheral nerve path of the involved tissue, or over a distal location
overlying any muscle that is not an antagonist to the muscle being stimulated.
Bipolar (Bi-Polar) Technique
This is the most commonly used technique for muscle stimulation. This
technique utilizes two electrodes but not exclusively of the same size. One
electrode should be applied over the motor point and the other electrode over
the belly of the muscle as far away from the motor point as possible. This
technique allows for more effective muscle and nerve fiber recruitment since
the entire neural innervation of the muscle is furnished with current.
Quadripolar (Quadri-Polar) Technique
This technique requires the use of two output channels and four electrodes
usually, but not exclusively of the same size. The two electrodes from one
channel are usually placed diagonally across the tissue area or joint to be
treated with the second channel electrodes placed on the opposite diagonal.
This ensures that the current will intersect and thus provide and interferential
pattern.
