adhesion to the skin.
3.
Place the electrodes on the skin in the desired positions. The electrode with
the black plug is the active electrode. The electrode with the red plug is the
indifferent electrode Adhesive tape will be required to hold the electrodes in
place. Care should be taken when putting on clothing over the electrodes and
wires.
4.
After use, remove the leads from the electrodes by gently pulling the plug. Do
not pull on the wires. Wash the gel from the electrode using warm water after
each use. Do not use soap or spirit based cleaner.
Electrodes Placement
Muscles are most sensitive to stimulation at the motor point, the point at which the
nerve enters the muscle. Motor points are generally situated about 1/3rd from the
proximal end of the muscle. Muscles can also be activated by stimulating the motor
nerve before it enters the muscle, for example, stimulating the common peroneal
nerve as it crosses the head of the fibula bone will recruit all the muscles that
dorsiflex and evert the foot, and extend the toes.
Generally speaking the active electrode (black pin) has a stronger stimulating effect
than the indifferent electrode (red pin). For this reason, place the active electrode
over the muscle or nerve from which you wish to achieve the biggest effect. Place
the indifferent electrode over a "neutral" position such as the back of the wrist, elbow
or knee, at the distal end of a muscle or over another muscle or nerve you also wish
to recruit. The indifferent electrode will give a slightly weaker effect. For example, if
