TENS is a form of electrotherapy that physiotherapists can use to alleviate pain. TENS is thought to produce pain relief via a mechanism called the "pain gate". Electrical stimulation from the TENS machine stimulates nerve fibres in the tissues which convey impulses to the spinal cord and brain. The nerve impulses created by the TENS machine are thought to override the painful nerve impulses which are created by your injury. This is described as closing the "pain gate" because it stops the painful nerve impulses passing along the spinal cord to your brain and consequently stops you from feeling the pain.
TENS is often very effective in conditions that cause high levels of continuous pain which cannot be readily treated with other techniques.
It is important to consult a physiotherapist before using TENS as they will be able to complete a thorough assessment of your injury which will determine whether it is an appropriate treatment method. If the physiotherapist feels it is appropriate, they will then need to find the correct setting on the TENS unit for you to use at home.
