What is TENS unit?

TENS, or transcutaneous electrical nerve stimulation, uses a low-voltage current to ease the pain. A TENS unit is a small, battery-operated, portable device that sends electrical signals to the sight of the pain and helps to manage that pain.

TENS delivers mild electrical impulses to electrode pads that are placed directly on your skin that travel to the nerves. Once TENS stimulates the nerve endings, it blocks the pain signal from traveling to the brain. This creates a pleasantly relieving, tingling sensation within the place of pain. Then the electrical signals of the TENS may also produce endorphins.

TENS unit used for managing pain such as knee pain, neck pain, shoulder pain, back pain, post-surgery recovery, and different chronic or acute pain.

How Does TENS Unit Work?

A TENS Unit works to ease pain in two ways. It refers to the first theory of TENS that inhibits pain signals as the gate control theory. The non-painful signals from TENS “close the gate” and stop the pain signals from reaching the brain.

The other evidence for the potency of electrotherapy as a pain reliever, is that the TENS treatment released endorphins, the body’s natural opiate-like painkiller. TENS helps with acute and chronic pain. It is shown that TENS alleviates osteoarthritis (OA) pain and reduces the requirement for pain medications.

You also need to confirm how many pads you need to put on the localized area of knee pain. Two or four pads are most frequently applied to treat pain. It typically uses two pads, while four electrode pads can cover a wider area. The spot where you may place the pads of your portable TENS unit depends on where the source of your pain is found. You place the pads where the source of your pain in the center position. Pace the electrode pad for knee pain, as pictured below:

Typically, for placing the pads, avoid the kneecap. Once using the TENS pads, you want to surround the kneecap by putting a pad on both sides. If needed, you’ll place four pads encompassing the knee. Once using four pads attach both lead wires and place the electrodes in a ‘square pattern’ close the area of pain. That looks like a criss-cross pattern.

The pad placement appears like a big “X” with the middle of the “X” being the center of your pain. If you’re experiencing pain within the back of your knee, you’ll place the pads in a criss-cross pattern there.

If you want to use two pads, 1 on either side of the knee, as pictured below:

Once you have positioned the pads, then turn on the TENS unit and set it to the desired level. You can use the TENS unit 2-3 times a day and about 30 minutes for each session. The TENS unit therapy with the home exercises and stretching helped the pain subsided and can provide some increased range of motion and flexibility.
