What is Tens?
Transcutaneous Electrical Nerve Stimulation is a battery powered electrical unit which uses electrodes placed onto the skin to deliver electrical impulses to the nerve fibres which lie underneath the skin surface.
It is used to provide pain relief by blocking pain signals to the brain via the spinal cord and peripheral nervous system, and also stimulates the production of endorphins, the body’s own pain relieving mechanism.
Usually the electrodes are placed around the pain area or on acupressure points. Unlike medication, TENS does not produce side effects such as nausea or drowsiness. It can be administered while you are going about normal activity and is not addictive.
HOW DOES TENS WORK?
The TENS Machine can work in two ways but firstly it is important to understand how the body feels pain.
Messages are sent from the brain to all areas of the body and back again by the nerves, which run from the brain down the spinal cord spreading out to the trunk, arms and legs. If you touch something hot a message will flash along the nerves, up the spinal cord and into the brain. A second message would immediately be sent back to the same area telling you to move your hand away. This process takes only a micro second.
TENs works by a method called pain gating where the stimulation of the TENs machine blocks the messages to the brain telling it the body is experiencing pain. It also encourages the brain to produce the bodies own natural painkilling hormones known as endorphins.
