Transcutaneous electrical nerve stimulation, commonly known as TENS is the use of low voltage electrical current to provide pain relief. TENS therapy is performed with a TENS unit, a small device that features electrodes. These electrodes are usually reusable self-adhesive pads and are placed on the area of pain.

The low voltage current is passed from the machine to the electrodes, then into the body. This stimulates the nerve endings and scrambles the signal, which reduces the feeling of pain. It encourages the body to release endorphins (pain killing hormones).

Many different problems can be alleviated with TENS therapy. Those who have rheumatoid arthritis can get relief, along with people who suffer from sciatica. In fact, lots of people with acute and chronic pains use TENS to help. The most common use for the TENS unit however is to treat back pain. Nowadays there are TENS units that have been designed specifically to target the lower back, some of these feature belts that wrap around the body, making it easier to position the electrodes on the painful area.

For anybody who is looking into TENS therapy, it is important that you do the correct research and equip yourself with the necessary knowledge before choosing a device. Decide on what you need from the unit and then read TENS unit reviews. Look for both positive and negative feedback – and also look into how much the electrodes cost to replace. They are reusable but some brands last a lot longer than others, and the replacement price can vary massively. Check whether the unit is rechargeable, if it’s not, think about buying some rechargeable batteries. Some devices can cost a lot more to run because of these two factors.

If you are going to buy a TENS unit, make sure that you have consulted with your doctor first. Note that there are certain exclusions, for example, people who have pacemakers should not use the devices. Always check first and make sure that it’s suitable for you.
