The stimulation modifies or blocks nerve activity to minimize the sensation of pain reaching the brain. It delivers mild electrical stimulation through thin, insulated electrical leads to dorsal root ganglia along the spinal column. The procedure is usually safe, but may be associated with certain risks including change in electrode position, breakage, battery failure, bleeding, infection and development of tolerance.ĭorsal column stimulators do not treat the underlying cause of pain, but with its use, the intensity, frequency and duration of pain are usually reduced, lowering the need for pain medication and sometimes surgery. During an outpatient procedure, a doctor implants under the skin near the buttocks. What are the Associated Risks and Complications of Dorsal Column Stimulator? However, EES is delivered with multielectrode. Second, the small therapeutic range-of-stimulation ( 1. Electrical impulses are generated at the pulse generator by remote control and are transmitted to the electrodes. Epidural electrical stimulation (EES) targeting the dorsal roots of lumbosacral segments restores walking in people with spinal cord injury (SCI). First, the threshold for dorsal column fiber stimulation generally exceeds the threshold for dorsal root fiber stimulation (due to the distance between epidural electrode and spinal cord). The remaining components are connected externally. This is done either surgically or through the skin under radiographic guidance.

Depending on the location of your pain, the electrodes are placed in the neck, upper or lower back region of the spinal cord. What Conditions Does Dorsal Column Stimulation Treat This FDA-approved procedure is used to treat a variety of chronic back pain conditions: Chronic Pain ongoing pain that is not alleviated with other treatments.

How is the Procedure of Dorsal Column Stimulator Performed?Ī dorsal column stimulator consists of electrodes, a battery-operated pulse generator, a remote control device and connecting wires. Dorsal column stimulation is a reversible neuromodulation technique. DCS acts either by blocking the pain impulse pathway or by stimulating the production of endorphins (chemical substances produced by the body that decrease the sensation of pain). It is used to treat chronic disabling pain such as failed back surgery syndrome and complex regional pain syndrome, which show little or no improvement with other treatments such as medication or surgery. The dorsal column stimulator (DCS) or spinal column stimulator is a device that relieves chronic pain associated with spinal nerves through electrical stimulation. A dorsal column stimulator, also known as a spinal cord stimulator, uses an implantable neuromodulation device that sends electrical signals to targeted areas of the spinal cord (dorsal columns) to treat pain.
