Electrotherapy uses electrical signals to interfere with the transmission of neural pain signals into the brain. It effectively slows down or distracts the message from the nerve to the brain. From a physiotherapy point of view, affecting one’s ‘Pain Gate’, whether in an acute or chronic pain episode, is a crucial area of treatment, and electrotherapy is a very useful resource where conventional medicines are not as effective. Electrotherapy can also involve the use of this electric current to speed tissue healing where tissue damage has also occurred.
