While TENS doesn’t hurt, the sensation, often described as a buzzing or tingling may be unpleasant to some people.Ī TENS machine is typically a small, portable unit made up of a battery powered stimulator about the size of a large mobile phone connected to at least two sticky electrode pads that attach to the skin around the source or location of the pain. The electrical impulses are sent transcutaneously - meaning across or through the skin - so no medicine or invasive techniques are needed to treat pain. The electrical currents from a TENS machine mimics this. The shin pain is deadened thanks to the rubbing sensation that is muting the signal to the brain. Most people have experienced this effect in some way or another, such as rubbing your shin after you’ve just banged it into something. Pain gate theory supposes that a nerve signal may be blocked or reduced in intensity by co-opting the nerve with other stimuli. Endorphins are a natural pain reliever released in the brain and TENS appears to trigger increased production. How a TENS machine actually blocks or reduces pain is not fully understood, but recent studies point to an interaction of a number of factors, including pain gate theory and endorphins. The electrical impulses appear to help block pain signals from reaching the brain, giving people suffering from chronic pain or other forms of long term discomfort a respite from their symptoms. In addition to manual therapeutic techniques, such as joint or muscle manipulation and massage, physiotherapists may also utilise a number of specialist tools to help them treat people in a non-invasive manner.Ī TENS machine is a device that utilises low voltage electrical current to offer pain relief. Some medical conditions or situations may prevent the use of TENS in the treatment of pain.They will not cure the cause of the pain, but may provide pain relief. TENS machines have few if any negative side effects but may not work for all people.These electrodes are placed on or around the source or centre of where the person feels pain.A TENS machine consists of a small stimulator box connected to two or more electrode pads by wires.TENS uses electrical stimulation to treat pain through a combination of factors, including the release of endorphins and overwhelming the pain signals with extra nerve impulses.
