Electrode Types and Sizes

Electrodes are available in a broad range of sizes and shapes. Since many electrodes are available, patients can select their required electrode according to their needs or the body part they want to use the electrode on. 

For instance, two of the smaller TENS patches on any of the sides of the spine. They can be used to treat neck pain by being applied to the back of the neck. The larger versions of the patches can be applied to treat muscular pain in the upper legs or the back.

Let us take a look at the standard shapes and sizes electrodes are available in:

2 X 2″ Square Electrodes

This is the most popular size and shape of electrodes. The majority of the TENS devices contain two output wires that are connected to two self-sticking electrodes each. So, that means simultaneously; four electrodes can be applied to the body.
