What Is A TENS Unit?
Transcutaneous Electrical Nerve Stimulation(TENS) is a small, battery-operated device that is used for pain relief. It involves the use of mild electrical current. The device features a lead that is connected to small pads known as electrodes. For therapy, the pads are directly attached to your skin. As you switch the machine on, small electrical impulses are delivered to the pain affected areas of your body. You may feel a tingling sensation as the machine runs. TENS therapy may reduce the pain signal going to your spinal cord and brain, which may help relieve pain and relax your muscles. TENS machines may stimulate the production of endorphins. Endorphins are the body’s natural painkillers. This machine may help reduce pain and muscle spasms caused by arthritis, period pain, endometriosis, back pain, knee pain, neck pain, and sports injuries.
How Does A TENS Unit Work And Where To Buy One?
To start the TENS therapy, you first need to plug the pad wires into the A and B channels that are located at the top of the device.
Snap the wire onto the pads for powered muscle stimulation. Ensure that each part is connected firmly. Peel off the protective film on the electrode pads and place them on the targeted area of pain relief. The pads have to be placed 3 cm apart, on each side of the desired area to avoid overlapping. Once the electrode pads are securely placed, switch on the machine. It will start automatically from mode 1 and level one. You can select the mode of your choice. Use the intensity buttons located on the left-hand side of the device to control the A1/A2 ports. For dual channels, alter the intensities on A and B channel (left side/right side). Increase the intensity gradually and gently to test your acceptance level of intensity. After using the device, turn it off completely and then unplug it. Make sure to keep the pads back into the pad holders to ensure the longevity of the pads.
Though you can buy a TENS machine online, it is best to consult your general physician. This way, you can get a proper assessment done and know whether you need a TENS machine or not. Also, your doctor may refer you to a physiotherapist or pain clinic. You can first try TENS therapy at the physiotherapy center, and if it works for you and provides relief, you can buy the device. Getting yourself acquainted with TENS therapy at the physiotherapy center will not only help you in making the purchase decision, but you will also learn how to operate the device. The therapy will be most effective only when the settings are adjusted correctly according to you and your condition. Let us now take a look at the best TENS units you can buy.
