Spinal cord stimulator overview
Informed by recognized medical guidance
Overview
A spinal cord stimulator is a small device that is placed under your skin to send mild electrical signals to your spinal cord. These signals can reduce the feeling of pain in certain parts of your body. It is used for long-term (chronic) pain that has not improved with other treatments.
Key facts
- The device does not cure the cause of pain, but can help manage it.
- You usually have a trial period first to see if it works for you.
- The stimulator is implanted by a surgeon, and you can control it with a remote.
Spinal cord stimulators are not very common, but they are used more often for people with certain types of chronic pain that haven't responded to other treatments.
It is mostly used in adults who have chronic pain conditions, such as failed back surgery syndrome, complex regional pain syndrome, or nerve pain (neuropathy).
Symptoms
- Sudden loss of feeling or movement in your legs.
- Severe headache that comes on quickly after the implant procedure.
- Signs of infection around the device site (redness, swelling, warmth, pus) with fever or chills.
- Any symptoms of stroke or heart attack, such as sudden chest pain, trouble breathing, or confusion.
- ⚠Increased pain at the implant site that does not improve.
- ⚠Burning or tingling that feels wrong or stronger than before.
- ⚠Swelling or bleeding from the wound that does not stop.
Common symptoms
- Ongoing pain in the back, legs, or arms that does not go away with rest or usual pain medicines.
- Burning, tingling, or shooting pain in a limb or part of the body.
- Pain that makes it hard to walk, sleep, or do daily activities.
Symptoms in children
- Spinal cord stimulators are rarely used in children. If considered, the child would be evaluated by a specialist pain team.
Symptoms in older adults
- Older adults may have age-related changes that affect the spine or nerves, leading to chronic pain that might be helped by a stimulator. The decision depends on overall health and other medical conditions.
Causes
Main causes
- Spinal cord stimulators are not a cause; they are a treatment. The conditions that lead to using one include nerve damage, failed back surgery, complex regional pain syndrome, and other chronic pain that does not respond to usual care.
Risk factors
- Chronic pain conditions that have lasted more than 6 months.
- Previous spine surgeries that did not relieve pain.
- Nerve injuries or conditions like peripheral neuropathy.
When to see a doctor
See a doctor urgently if:
- If you have sudden new symptoms like weakness, numbness, or loss of bladder or bowel control.
- If you think your device is causing a problem, such as strange sensations or pain.
Book a routine appointment if:
- If you have chronic pain that limits your daily life and other treatments have not helped, ask your doctor about whether a spinal cord stimulator might be an option.
Diagnosis
You do not get diagnosed with a spinal cord stimulator. Instead, a specialist (like a pain doctor or surgeon) will evaluate your chronic pain to see if a spinal cord stimulator might be right for you. They will review your medical history, do a physical exam, and may order tests to understand the cause of your pain.
Tests that may be done
- MRI or CT scan to look at your spine and nerves.
- Nerve conduction studies to check how well your nerves are working.
- A psychological evaluation to make sure you are prepared for the device.
What to expect at your appointment
Before the implant, you will have a trial period where a temporary stimulator is placed for a few days to see if it reduces your pain. If the trial is successful, you will have a surgery to place the permanent device under your skin.
Treatment
A spinal cord stimulator is a treatment option for chronic pain that has not improved with other therapies. It does not remove the pain completely but can make it feel less intense. The device sends small electrical pulses to the spinal cord to block or change pain signals.
Self-care at home
- After implant, keep the wound clean and dry as instructed by your healthcare team.
- Avoid heavy lifting or bending for a few weeks.
- Use the remote control to adjust the stimulation level for comfort.
Medical treatments
Before considering a spinal cord stimulator, doctors usually try other treatments such as physical therapy, pain medicines (like anti-inflammatory drugs or nerve pain medications), nerve blocks, or injections. If these do not provide enough relief, a spinal cord stimulator may be discussed.
When is surgery considered?
Surgery is needed to place the spinal cord stimulator. The procedure is done by a surgeon and involves making a small cut in your back to put the thin wires (leads) near the spinal cord and a small battery pack under the skin, usually in your lower back or buttock area.
Living with this condition
With a spinal cord stimulator, you can often reduce your pain and do more of your normal activities. You will have a remote to turn the device on/off and adjust the settings. Some people can feel a mild tingling (called paresthesia) where the pain was. You will need to charge the device battery regularly (if it is rechargeable) or have it replaced every few years.
Lifestyle tips
- Avoid contact sports or heavy lifting that might damage the device.
- Let your doctor know before having any MRI scans, as some older devices are not safe for MRI.
- Inform airport security about the device when traveling (you will get a card to show).
Diet and exercise
A balanced diet and regular, gentle exercise (like walking or swimming) can help your overall health and pain management. Your doctor or physiotherapist can advise on safe activities.
Mental health and emotional wellbeing
Living with chronic pain can be stressful, and a spinal cord stimulator may improve your mood by reducing pain. However, it is normal to feel anxious before or after the procedure. Talking to a counselor or joining a support group may help.
Prevention
The need for a spinal cord stimulator cannot be prevented because it is used to treat chronic pain that has already developed. However, treating pain early with other methods may reduce the chance of needing a stimulator.
Complications
If left untreated
- Without a spinal cord stimulator (if you are a candidate), chronic pain may continue to limit your daily activities and quality of life.
Long-term outlook
For many people, a spinal cord stimulator can provide significant pain relief and improve function. It is not a cure, but it can make a big difference. Success rates are good when the device is used for the right condition and with proper follow-up care.
