The electrode placement depends on the type of stimulation you would like to use - TENS or EMS - and the body part you would like to treat.
Electrode Placement Guide
For suggestions regarding placement of the electrodes, see the ‘Electrode Placement Guide’ below. For both TENS and EMS, the optimal electrode positions may vary slightly from person to person. So try moving the electrodes around until you get the most effective results. In any case, the electrodes should be placed at least 3 cm apart from each other.
For TENS (programs 1-15)
As a rule, place the electrodes on or near the area where you have pain. Try to find an electrode position where you experience a strong but comfortable sensation from the stimulation. Stimulation may result in visible muscle contraction, especially in burst TENS programs (programs 7 to 11). This is not harmful, but if you find these contractions uncomfortable, try moving the electrodes to a different place, reduce the stimulation intensity or choose a different program.
For EMS (programs 16-20)
As a rule, place the electrodes on the muscle that you would like to strengthen so that the two electrodes are alongside of the muscle. One electrode should always be placed on the middle of the muscle belly. When using EMS programs, muscle contraction is a desired effect and should always occur. If no muscle contraction occurs in an EMS program, you have not placed the electrodes correctly or you have chosen a too low intensity. If the muscle contractions feel uncomfortable, try varying the placement of the electrodes.
Do not place electrodes over the carotid sinus on the sides of your neck or on the front of your neck, across your chest or on your head.
Do not place electrodes on red or inflamed skin and skin with open wounds, on cancerous lesions or rashes.P74
