The brain's reaction to chronic pain can be compared to learning to play the piano or memorizing a poem - the more the body "practices" processing pain, the stronger the connections between pain nerves and the brain become.

When someone is injured, the brain sets up a process to heal the injury. For example, cells carry away dead tissue or it increases blood flow to the area. Eventually, the brain realizes the injury has healed and it cuts off the pain message.

But for some, the brain never sends the pivotal message saying "there's no more injury here so you can stop the pain signal." That's where Calmare-Scrambler therapy comes in.

The MC-5A Calmare Scrambler Therapy device provides treatment by using rapidly changing electrical impulses to send a “non-pain” message along the same pain fibers that are sending the “pain” message to the brain. This process changes the message to the brain from “pain” to “non-pain.”
