Electrodes positioning
We know that an electrical generator
for producing a current flow must be
“closed” on a load. The load, in the
electro stimulation, is represented by
the muscle to be stimulated. The
connection between the generator and
the treatment area (load) will be
performed by means of a pair of
conductive electrodes, having the job
to transfer the electrical potential
(voltage) to the load (muscle). A
closed circuit needs at least a pair of
electrodes; it is impossible to obtain a
current flow with only one electrode. A
current flow must always have an input
point and an output point.
If the aim of the electrical stimulation is
to produce a muscle contraction, at
least one of the two electrodes must
be placed on that muscle, but where is
the best position?
