If you were to hold a TENS and EMS unit side-by-side, you wouldn't be able to tell them apart. One of the most popular TENS unit topics is how they are different from EMS units? EMS stands for electrical muscle stimulation.

Today: Many modern TENS units are offered to combat pain offering an effective alternative to addictive pain medicines.The small handheld device allowed for mothers to manage pain themselves while giving birth without an epidural for a natural birth.

1987: Ray Kriesler invents the first TENS unit specifically for giving birth.1974: American Neurosurgeon Clyde Norman Shealy patents the first current TENS unit.This finding was a significant breakthrough that would help bring TENS therapy into modern medicine. 1964: Ronald Melzack and Patrick Wall release "Gate Theory," explaining how pain can be managed through electrical shocks.These early forms of TENS therapy units would die off with the emergence of narcotic pain killers. 19th Century: Electrotherapy began being used commonly as a form of pain relief, with machines invented that administered static electricity.He would offer this form of electrotherapy to treat headaches, migraines, and even gout. 2500 BC: Hieroglyphs show electric eels being used as a form of treatment. Scribonious Largus, a Roman physician, noted that standing on an electrical fish offered a way of pain management.We've broken down a brief period to help you understand not only how old TENS therapy is, but how it has evolved. TENS therapy is nothing new it's been used for quite some time now. In short, the pain gets temporarily blocked. The tingling/massaging sensation doesn't allow pain fibers to transmit painful feelings to the brain. By rubbing or shaking the injured area, we're creating more large fiber activity, which diminishes small (pain) fiber activity, thus reducing the sensation of pain.Ī TENS unit activates large fibers to overpower small fibers by creating a tingling or massaging sensation to close pain gates. Pain gate theory explains why we rub or shake injuries after they occur. This does not allow pain nerves to be sent to the brain (i.e., no pain!). However, the pain gate is closed when large fiber activity is more robust than small fibers. When small fiber activity is more abundant than large fiber activity, the pain gate is open, allowing pain to be transferred to and decoded by the brain. These fibers carry information from the area of pain to the spine.

There are two types of nerve fibers, small (pain fibers) and large (fibers for skin senses such as touch and pressure). Essentially, the theory states that t here are "nerve gates" at the end of your spine that control if pain signals are allowed to pass to the brain to be decoded. Pain gate theory explains how nerves perceive pain, and touch impedes that perception. Pain gating is a theory created by Ronald Melzack and Patrick Wall in the early 1960s.

The brain then decodes them into the feeling of pain. When experiencing pain from an injury, pain signals are sent to the spine, which is sent to the brain. Think of it as the body's car alarm when something's not right. Pain is essentially a warning system in the body that lets your brain know something is wrong. To understand pain gating, we must first understand how pain works.
