Spinal Cord Stimulation
Spinal Cord Stimulation (SCS) uses groundbreaking technology that works by introducing an electrical current into the epidural space near the source of chronic pain impulses. Under a local anesthetic and minimal sedation, a doctor will first place the trial SCS leads into the epidural space. The SCS lead, a soft thin wire with electrical leads on its tip, is inserted into the epidural space through a needle in your back. The trial stimulator is typically worn for 5-7 days as the lead is taped to the back and connected to the stimulating device. If the trial successfully receives the pain, you may have the option to use the device on a permanent basis.
The implanted device near the area of pain produces a low-voltage current and creates a sensation that interferes with the brains ability to sense the previously perceived pain, even replacing those sensations with pleasant ones. The intensity of the stimulator can be changed, and the system can be turned on and off as necessary to provide optimal pain relief as experienced by the patient.
The stimulation trial is a short procedure, and implantation will be performed under light sedation. A local anesthetic is used to numb the area where the leads are inserted. During the procedure, one or more leads are placed in the space along the spinal cord. The exact placement depends on the location of the pain. When the leads are positioned in the best location, they are connected to a portable external generator. Once connected, the system generates mild electrical impulses that will be programmed to replace the areas of intense pain with a more pleasant sensation known as paresthesia.
