![]() ![]() Before implantation of the permanent device, a trial implantation is done by placing the stimulator at the appropriate segment of the spinal cord. There are different techniques for the implantation of a spinal cord stimulator. A SCS provides significant relief in performing routine activities and decreases the requirement for pain medications.Ī SCS is effective in the management of chronic pain in the lower extremities or back and also in various other disorders such as sciatica, failed back surgery syndrome, complex regional pain syndrome (CRPS), and arachnoiditis. Therefore, before implantation of the permanent device, trial stimulations are performed to evaluate the patient’s response. There is interindividual variation in the extent of pain relief with a SCS. ![]() SCS only provides symptomatic relief and does not cure the root cause of pain. These signals interrupt the transmission of pain signals from the spinal nerve fibers to the brain, thus relieving the pain. A SCS comprises of a small wire that transmits the electrical signals from a pulse generator to the leads. A manually operated remote for adjusting the electrical signalsĪ spinal cord stimulator (SCS) is surgically implanted in the subcutaneous tissue of the lower back, beneath the skin, and is also known as a dorsal column stimulator.An extension wire connecting the pulse generator to the lead.A lead with many electrodes which delivers the electrical impulses to the spinal cord.An implantable pulse generator with battery that generates electrical signals.There are different types of stimulation systems but the most common among them is an internal pulse generator with battery. Specific segments of the spinal cord are stimulated through electrical signals, generated by a spinal cord stimulator, which may be associated with a slight prickling or tingling sensation. Spinal cord stimulation is used for the management of chronic pain in arms and legs that has not responded to conventional modalities of treatment.
