Spinal cord stimulation (SCS) has become a well-accepted treatment modality in the management of persistent chronic pain offering significant pain relief, increased activity levels, and augmented improvements in quality of life. The neurostimulator device has many ways of sending out signals to disrupt the pain signals traveling up to the brain some ways that are not overtly noticeable, others that work in a fashion that may cause a slight tingling sensation that the individual may perceive. SCS is done with an electronic medical device that uses special wires called “leads,” which are placed into the epidural space adjacent to the dorsal column of the spinal cord. What You Need to Know Spinal cord stimulation is used most often after nonsurgical pain treatment options have failed to provide sufficient relief. This medical technology has been utilized for approximately 60 years. A spinal cord stimulator is an implanted device that sends low levels of electricity directly into the spinal cord to relieve pain. This ostensibly leads to suppression of hyperexcitable wide dynamic range neurons (WDR), which are sensitized and hyperactive in chronic pain states. While the efficacy of SCS has been demonstrated, the precise mechanism of action and nature of the fibres activated by stimulation remain largely unexplored. This is where the ascending tracts pass without decussation to the gracile and cuneate nuclei of the medulla oblongata. Spinal cord stimulation (SCS) treatment for chronic pain relies on the activation of primary sensory fibres ascending to the brain in the dorsal columns. Historically, antidromic activation of the nerve fibers in the dorsal columns has been thought by some to be capable of ‘closing the gate’ resulting in analgesia, while orthodromic activation elicits paresthesias Citation 1. This stimulation pattern selectively activates inhibitory interneurons in the dorsal horn (DH) at low stimulation intensities, which do not activate the dorsal column fibers. Spinal cord stimulation (SCS) is a treatment for pain that uses a mild electric current to block nerve impulses in the spine. In SCS the placement of epidural electrodes is generally targeted at the dorsal column of the spinal cord however, in patients with segmental pain (single dermatome), stimulation is focused at the corresponding dorsal root. This disruption in the dorsal column of the spinal cord interrupts these signals as they travel to the brain, which theoretically should result in less perceived pain by the individual. Paresthesia-based spinal cord stimulation (SCS) has been used for decades to treat chronic pain. Spinal cord stimulation (SCS), also called neurostimulation, disrupts the electrical signals that travel between the nerves of the body up the spinal cord to the brain. ![]()
