Frequently Asked Questions
About Spinal Cord Stimulation
Find answers to common questions about spinal cord stimulation, including how it works, who may benefit, and how it may help manage arm, leg, and low back pain.
Spinal Cord Stimulation for Arm Pain
1. What is a spinal cord stimulator, and how can it help arm pain?
A spinal cord stimulator (SCS) is a small implanted device that delivers mild electrical impulses to the spinal cord. These signals help modify how pain messages are processed before they reach the brain. Spinal cord stimulation may reduce chronic arm pain, improve daily function, and decrease reliance on pain medications in carefully selected patients.
2. What arm conditions can be treated with spinal cord stimulation?
Spinal cord stimulation may be considered for chronic arm pain caused by conditions such as: •Complex Regional Pain Syndrome (CRPS) •Persistent pain after neck or arm surgery •Cervical radiculopathy (pinched nerve) •Peripheral nerve injuries •Certain chronic neuropathic pain syndromes A comprehensive evaluation is necessary to determine whether spinal cord stimulation is appropriate for your condition.
3. How do I know if I am a candidate for a spinal cord stimulator?
Candidates typically have chronic pain lasting several months or longer that has not responded adequately to medications, physical therapy, injections, or other conservative treatments. Before permanent implantation, nearly all patients undergo a temporary trial lasting several days. If the trial provides meaningful pain relief and improved function, a permanent device may be recommended.
4. Is spinal cord stimulator implantation a major surgery?
No. Implantation is considered a minimally invasive procedure performed through small incisions, usually on an outpatient basis. Most patients return home the same day and gradually resume normal activities over several weeks. Your physician will provide detailed instructions regarding activity restrictions during the healing period.
Spinal Cord Stimulation for Leg Pain
1. Can a spinal cord stimulator help chronic leg pain?
Yes. Spinal cord stimulation is commonly used to treat certain types of chronic leg pain, particularly pain caused by nerve injury or nerve dysfunction rather than muscle or joint disease. The device changes how pain signals travel to the brain and may reduce pain while improving walking, sleep, and overall quality of life.
2. What leg conditions are treated with spinal cord stimulation?
Spinal cord stimulation may be appropriate for selected patients with: •Chronic sciatica (lumbar radiculopathy) •Failed back surgery syndrome (persistent pain after spine surgery) •Complex Regional Pain Syndrome (CRPS) •Painful peripheral neuropathy, including diabetic neuropathy in selected patients •Chronic neuropathic leg pain that has not responded to conservative treatment Your physician will determine whether your specific diagnosis is likely to benefit from spinal cord stimulation.
3. Will I have a chance to try the spinal cord stimulator before surgery?
Yes. One of the major advantages of spinal cord stimulation is that it includes a temporary trial before permanent implantation. During the trial, temporary leads are placed through a needle, and the external stimulator is used for several days. If you experience significant improvement in pain and function, you and your physician may decide to proceed with permanent implantation.
4. Will a spinal cord stimulator eliminate my pain completely?
The goal of spinal cord stimulation is meaningful pain reduction and improved quality of life, not necessarily complete elimination of pain. Many patients experience enough relief to improve their daily activities, sleep better, and reduce pain medication use. Individual results vary, and your physician will discuss realistic expectations based on your diagnosis and overall health.
Spinal Cord Stimulation for Low Back Pain
1. Can a spinal cord stimulator help chronic low back pain?
Yes. Spinal cord stimulation (SCS) may help selected patients with chronic low back pain, particularly when conservative treatments such as medications, physical therapy, injections, or previous surgery have not provided adequate relief. The device delivers mild electrical impulses to the spinal cord that modify how pain signals are processed before they reach the brain. The goal is to reduce pain, improve function, and enhance quality of life rather than simply mask symptoms.
2. Who is a candidate for spinal cord stimulation?
You may be a candidate if you have chronic low back pain that has persisted for several months despite appropriate treatment. Spinal cord stimulation may be considered for patients with: •Persistent pain after lumbar spine surgery (failed back surgery syndrome or persistent spinal pain syndrome) •Chronic low back pain with or without leg pain •Degenerative spine conditions in selected patients •Chronic neuropathic pain that has not responded to conservative therapies A comprehensive evaluation, including review of your medical history and imaging studies, is necessary to determine whether spinal cord stimulation is appropriate for your condition.
4. Is spinal cord stimulator implantation a major surgery?
No. Permanent implantation is a minimally invasive outpatient procedure performed through small incisions. Most patients return home the same day. Recovery generally involves limiting bending, twisting, and heavy lifting for several weeks while the leads heal into position. Your physician will provide individualized instructions to help maximize the success of the implant.
5. Will a spinal cord stimulator cure my back pain?
A spinal cord stimulator is not a cure for the underlying spine condition, but it may significantly reduce chronic pain and improve daily function in appropriately selected patients. Many people are able to walk farther, sleep better, participate more fully in work or hobbies, and reduce their reliance on pain medications. Individual results vary, and the goal is meaningful improvement in pain and quality of life rather than complete elimination of pain.
3. Can I try a spinal cord stimulator before having it implanted?
Yes. One of the unique advantages of spinal cord stimulation is that almost every patient first undergoes a temporary trial. During the trial, thin leads are placed through a needle, and an external stimulator is worn for several days. This allows you and your physician to evaluate whether the therapy provides meaningful pain relief and improved function before deciding on permanent implantation.
