Replacement electrodes are adhesive pads used with a TENS machine to deliver electrical stimulation to the skin. They come in different sizes, including 5 x 5 cm and 5 x 9 cm, to allow for better coverage and flexibility of use. It is important to replace the electrodes periodically to ensure maximum effectiveness and to prevent skin irritation from prolonged use of the same electrodes.
It is recommended to use the correct size and type of electrode for your TENS machine, as using the wrong type may result in reduced efficacy and discomfort. Some TENS machine manufacturers also offer specialized electrodes, such as self-adhesive or reusable options, so it is important to choose the best option for your specific needs and TENS machine.
