We use this principle unconsciously when we are hurt and touch or hold the area around the injury. This finding was explained by the Gate Control Theory of Pain.Īccording to this theory, when there is a large amount of nerve stimulation coming from a part of the body, the brain “closes the gate,” which results in a substantial reduction in how much your brain perceives that stimulation. Though intense electrical shocks can be painful, they found that less powerful pulses delivered to the nerves in a painful area decreased the perception of pain. In the late 1960s, researchers discovered a technique for relieving pain using electrical pulses. In other cases, however, electricity can disrupt and reduce pain. Typically, people think of electricity as causing pain for example, when a person receives an electric shock from a wall outlet. Because this is an electrochemical process, it can be influenced by electricity. The perception of pain involves signals transmitted by the nerves throughout the body to the brain. Most patients start with a test device that they wear for a temporary period before installing You can change the intensity of the stimulator and turn the system on and off as necessary to provide optimal pain relief. You control the delivery of these low-level electrical impulses to the area. These new sensations interfere with your perception of pain, especially chronic nerve and back pain. This is typically a slight tingling feeling. It interferes with the perception of pain received by the brain by creating another sensation that replaces the pain. The implanted device near the area of pain produces a low voltage current, which creates a sensation that blocks the brain’s ability to sense the previously perceived pain. Your doctor implants a small device near your spinal cord in the epidural space. This “pacemaker for pain” works by blocking pain signals from traveling up through the spinal cord to the brain. Spinal cord stimulator therapy is an exciting procedure that is becoming increasingly popular for the treatment of many causes of chronic back pain.
