Choosing the Right TENS

A TENS Machine stands for Transcutaneous Electric Nerve Stimulation machine. A tens machine is a small battery-operated device that is a method of pain relief involving the use of a mild electric current.

The device has leads that are connected to sticky pads also called electrodes. These pads are attached to the skin on the pain affected area. When turned on, you will feel a tingling sensation due to the delivery of the small electric impulses to the pain affected area. To put it simply, a TENS device stimulates your nerve by sending electric currents through your skin. It is a safe and effective way to manage pain.

How Tens Machine Works

The Endorphin Release theory suggests that TENS works by sending electric current that only focuses on the sensory nerve endings that control pain. With the help of these currents passing to the brain, it releases endorphins which are also known as the body’s natural painkiller.

These endorphins reduce the pain felt by the patient. They act exactly like prescription drugs but without the side effects.

According to the Gate Control Theory, a neural mechanism located in our spines acts as a gate that closes and opens when it receives signals from the brain. The electric signals produced by the TENS interfere with the pain determining signals in the body. The gate reacts to the signals produced by the TENS machine rather than that of the body so even if there is a pain you brain will not be able to interpret it.

TENS can be used to alleviate pain caused by a wide range of problems like back pain, Joint pains, arthritis, sciatica, nerve pain, bone pain, Neck pain, Sports injuries, Muscle pain, and even period pain. Although sometimes, it is also used during labour as a method of pain relief.

Although the TENS is used mostly as a method of pain relief, it can also be used as a pain inhibitor during medical procedures. Using the machine can also aid in reducing nerve pain and muscle inflammation. Using the TENS machine over time can lead to better health and wellness in general.

Benefits of Using TENS:

  • The most significant advantage of using a TENS device decreases the use of painkillers or analgesics. It is an affordable option to relieve pain without using any kind of medication. Unlike pain medication, TENS can be used without fear of any side effects and with a promise of bouncing back to normalcy pretty quickly.
  • It is portable and easy to use a device that has no adverse effects on the body. It works in a way that makes the body respond naturally and efficiently.
  • Since it stimulates the nerve and muscles, it is an incredible device that can be used to reduce fatigue and exhaustion caused by our sedentary and fast-paced lifestyles. Even TENS unit also helps to reduce muscle inflammation.
  • With the right kind of stimulation, it can reduce inflammation located deep inside the muscle fibres and also relieve pain from pinched nerves and sciatica.
  • The device also acts as a natural massager which in turn facilitates motion within the body and improves motor function. It aids in blood circulation and reduces muscle spasms. It has even found to improve sleep cycles and patterns.

How to Use the TENS Unit?

Since it is a medical device, be sure to check with your doctor before using the device. Also, read the manual and follow the instructions given clearly so as not to injure yourself. While every device has its own specific rules and instructions, the most basic ones are listed below:

  • Gently place the sticky pads or the electrodes on the affected area.

  • Start the TENS unit at its lowest setting and then gradually increase the setting to your comfort.

  • Never place the pads on your face, swollen or inflamed areas or directly on the heart.

  • Avoid touching the gel on the pads to increase its lifespan. Pour a few drops of water on the pad before attaching it to clean skin. Always put the protective films on the pads before putting them back in the box.

  • Ensure that the unit is adequately charged before use. If it is battery operated then make sure to change the batteries often.

  • Store the unit in a cool and dry place.

  • Remove the lead wires after using the TENS unit and place them in the box when they’re not in use.

Opt for a good TENS unit to eliminate pain. Do research about the efficiency of the machine and its price-worthiness before making the purchase.
