Use of tens unit


It is normal for people to suffer from any sort. This pain varies from mild to a severe one. Mild pain can be controlled by using a painkiller while a severe one needs a therapy. Sometimes, pain becomes unbearable for a person and he looks for certain ways to take relief from the pain. At that moment, the tens unit therapy would work best for him.

What is a Tens Unit?

TENS basically stands for Transcutaneous Electrical Nerve Stimulation. These are used as pain killers but it particularly works for nerve related pain conditions. The TENS machines relief pain by sending pulses over the skin surface and the nerve strands. These stimulating pulses avoid the pain signals to reach the brain. Apart from sending pulses, these machines help the body to produce its own natural painkillers known as Endorphins

How does tens unit work?

A tens unit works with different adjustable settings. These settings are used to control the stimulation intensity by managing the voltage level. In this process, the electrodes are attached to the particular part of the body depending on the pain location. The current then travels through the nerve pathways to produce a tingling sensation in order to reduce the pain perception. It is a drug-free method for reducing pain and it is often used for improving the quality of life for people having pain throughout the life.

How the tens unit eliminates pain?

Two theories are used as an explanation about how a tens unit reduces pain. These theories are discussed below:

  • Gate Control Theory

According to gate control theory, the spinal cord neural mechanism functions as a gate which allows the signals to flow of signals from the brain periphery. The shutting down or opening up of a gate depends entirely on the type of signals it is receiving from the brain in order to change the pain perception. The transmission of pain messages is blocked through these frequencies which in turn, relief the pain to a larger extent.

  • Endorphin Release Theory

According to Endorphin Release theory, the electrical impulses lead to the production of endorphin in the body. Endorphin is a natural morphine-like substance which prevents the transmission of pain messages to reach the brain.

Does tens unit works for chronic pain?

Many studies are conducted to investigate whether a tens unit would relieve the chronic pain or not. Many of those studies indicated that the best tens unit can help people with a chronic pain while the other few researchers reported that tens unit is not helpful for every individual. However, the tens unit has just a few side-effects and it would not interfere with the individual’s medication so this fact makes it popular among people.

Benefits of tens unit

Tens unit has following health benefits:

  • Reduces the chronic pain
  • Lower down the stress level by reducing the pain.
  • Better sleep pattern which results in a fresh morning the next day.
  • Enhances the energy level and avoid early tiredness.
