A trans-cutaneous electrical nerve stimulation (Tens) Unit is an equipment that helps in reduction of pain. The device normally uses fewer harmful electronic signals to help control pain, where electrodes are placed on your skin. Tens Units generally uses a small battery for operating the machine. A lot of questions will linger on many individuals’ minds, when asking themselves how do Tens Units relieve pain? Well, to understand this you must know how these are used. The Tens Unit is hooked to a belt and is connected to two electrodes. Then the electrodes of the device carry an electric current from the Tens device to the affected part. Electrons transmitted, usually do not have pain.
How do Tens Units Relieve Pain?
Tens Units work to disrupt the pain cycle by delivering a painless sensation to the skin around the affected part. Tens Unit device regulates sensations from that area. It closes the pain loopholes. It can be applied on with various frequencies; from high to low or from low to high, probably depending on the level of pain. The site of electrode application of Tens is basically at the site of injury. If on a high pulse rate, the electrical impulses generated by the Tens interfere with and block the pain messages sent to the brain. This also happens due to the gate control theory of pain. There is normally a gate mechanism in the nervous system that sends the messages through the brain and when it is open, the pain messages get through to the brain. While when closed, these pain messages are blocked, and we do not get to feel the pain. The Tens Units stimulate non pain carrying nerves and close down the gate. If the Tens Units are on a low pulse rate, the body gets stimulated to make its own pain easing chemicals, which block pain chemicals.
How To Use A Tens Unit To Relieve Pain?
The good thing with Tens Units is that they are designed in such a way that you can move around with them working. Before you place the electro pads on the surface of your skin, you have to ensure that the machine is switched off. Furthermore, you have to make sure that the skin where you are placing it is clean, and that it is dry with no open wounds and cuts or injuries. Set the pulse rate to the required setting. When you turn on the machine, you will feel a sensational feeling, which will eventually start to drop right away slowly by slowly, and it causes stimulation on the body, which reduces the pain. The Tens Unit relieves pain from various problems associated with muscles, joints and nerves and there are usually no side effects when using a Tens Unit. The best thing about this is that you can control it as the user, which means that you can adjust it without having to visit a medical center or the doctor. It is normally safe enough to use several times a day.
