Electrodes are central to all branches of electrotherapy. Their role is to facilitate the transmission of electric signals into the body. They do this by achieving a sound electrical contact between the patient’s skin and the device generating the electrical signal. This device could be a TENS machine, ultrasound unit, etc.
Probably the most important factors to consider in choosing the correct electrode is size and shape. The correct size in any particular case depends on the area of the body that will be treated.
The main objective will be to make good electrical contact throughout the surface of the electrode. You may find that a smaller electrode works better on more contoured body areas.
The shape of the electrode can also be an important factor in ensuring good electrical contact. Depending on the specific area being treated, a round electrode may be a better choice than a square one, or vice versa.
The most commonly available electrode sizes and shapes are:
This (or similar) electrode sizes are usually used in sets of 4. Typically, you buy an envelope of electrodes consisting of 10 sets of 4.
Besides the correct size and shape, you should try to choose electrodes that offer:
If you have sensitive skin or a history of latex allergies, you can choose to invest in latex free electrodes.
Electrodes are frequently used for pain relief in physical therapy. They provide a non invasive and efficient mechanism for managing pain and helping the patient comply with the prescribed rehabilitative program.
Electrodes are frequently used with Transcutaneous Electrical Nerve Stimulation (TENS) therapy to achieve this objective.
Electrodes can be used with TENS devices to mitigate pain from a wide variety of conditions. These include carpal tunnel syndrome,, arthritis, plantar fasciitis,frozen shoulder, sciatica and many others.
Electrodes can also be used with combination units (e.g. that combine therapies like ultrasound and TENS) for even greater efficacy.
Some tips for best practices when using your electrodes are:
