A thin tube, or catheter, is inserted into the fluid-filled area around the spinal cord known as the intrathecal space. To begin the procedure, the person is placed under local or general anesthesia. Sending medication to the pain receptors near the spine interrupts pain signals to the brain, easing the perception of pain. Medication is delivered directly to the spinal cord when an intrathecal pain pump is implanted. Effectiveness of cervical spinal cord stimulation for the management of chronic pain. , 3 Deer TR, Skaribas IM, Haider N, et al. Novel 10-kHz High-frequency Therapy (HF10 Therapy) Is Superior to Traditional Low-frequency Spinal Cord Stimulation for the Treatment of Chronic Back and Leg Pain: The SENZA-RCT Randomized Controlled Trial. About 50% to 60% of people using a low-frequency system and 80% or more of those using a newer high-frequency system achieve major relief.Ģ Kapural L, Yu C, Doust MW, et al. The other drawback is that spinal cord stimulation does not relieve pain for everyone who uses it. See Disadvantages and Risks of Spinal Cord Stimulation Serious complications, such as a hemorrhage or neurological damage-including paralysis-are rare. See Advantages of Spinal Cord Stimulation Disadvantages and Risksĭevice-related problems are fairly common, and there is a small risk of infection. 2016 9:481-92.] Many people using spinal cord stimulation are able to reduce or stop taking opioid pain medications. A review of spinal cord stimulation systems for chronic pain. Stimulation therapy does not eliminate all the pain, but pain is reduced by at least half for the majority of patients, leading to a major improvement in daily activities.ġ Verrills P, Sinclair C, Barnard A. Some patients have both spinal cord stimulation and peripheral nerve field therapy at the same time. The patient is awakened during implantation surgery to provide feedback on where the pulses should be directed to relieve pain. See Spinal Cord Stimulation: The Trial Period (During the trial period, an exterior generator is used.) In both types of stimulation, a small implanted generator sends the electrical pulses and is attached by a wire to the leads. In peripheral nerve field therapy, the leads are placed just under the skin. To begin spinal cord stimulation, thin insulated wires called leads are equipped with electrical contacts and inserted into the space surrounding the spinal cord. See Spinal Cord Stimulation for Chronic Back and Neck Pain Mild electrical pulses are directed to disrupt pain messages to the brain, reducing the feeling of pain. Spinal cord stimulation therapy and peripheral nerve field stimulation are related types of electrical stimulation that treat chronic pain.
