Chronic pain can dramatically affect quality of life, and for many patients, spinal cord stimulators (SCS) offer a promising solution. These devices deliver electrical impulses to the spinal cord, interrupting pain signals before they reach the brain. But a common question among patients considering or living with an SCS is: How long do spinal cord stimulators last?
To provide clarity, we spoke with Jordan Sudberg, a pain management specialist who has helped numerous patients manage chronic pain using spinal cord stimulation technology. Dr. Sudberg breaks down the factors that affect the lifespan of spinal cord stimulators, what patients can expect, and how to maximize device longevity.
What Is a Spinal Cord Stimulator?
Before diving into longevity, it’s important to understand what an SCS does. A spinal cord stimulator is a small, implantable device consisting of leads (thin wires) placed near the spinal cord and a pulse generator implanted under the skin, typically in the abdomen or buttocks.
The device sends mild electrical pulses that interfere with pain signals traveling to the brain, helping reduce the sensation of pain.
How Long Do Spinal Cord Stimulators Last? The Basics
According to Jordan Sudberg, the lifespan of spinal cord stimulators depends primarily on the type of pulse generator implanted:
- Rechargeable Devices: These newer SCS models have batteries designed to last 7 to 10 years or longer, with the patient recharging the device regularly (typically weekly).
- Non-Rechargeable Devices: Older or some simpler SCS models have batteries that last about 3 to 5 years before needing replacement surgery.
“Rechargeable systems have revolutionized spinal cord stimulation,” Dr. Sudberg explains. “They offer longer device life and fewer replacement surgeries, which reduces risk and inconvenience for patients.”
Factors That Influence How Long Your SCS Will Last
Several variables impact the effective lifespan of a spinal cord stimulator:
- Type of Device: Rechargeable vs. non-rechargeable batteries play the biggest role. Rechargeable batteries generally outlast non-rechargeable ones by years.
- Usage Patterns: The amount and intensity of stimulation you use daily affect battery drain. Higher settings or continuous use can reduce battery longevity.
- Technological Advances: Newer models come with improved battery technology, better leads, and optimized energy usage that extend lifespan.
- Patient Activity: Physical activity and body type may impact lead positioning and battery function over time.
- Maintenance: Proper care and follow-up can prevent complications that might necessitate premature replacement.
What Happens When the Battery Runs Out?
When the battery in a spinal cord stimulator nears depletion, the device’s effectiveness decreases, and the patient may experience a return of pain symptoms.
For non-rechargeable devices, replacement requires minor surgery to remove the old generator and implant a new one.
For rechargeable devices, patients simply need to keep up with regular charging. If the battery eventually reaches the end of its lifespan (after many years), replacement surgery is needed but typically much less frequently.
Dr. Sudberg notes, “Many patients choose rechargeable devices to avoid frequent surgeries and maintain consistent pain relief.”
Signs You May Need a Battery Replacement or Device Check
- Decreased pain relief or sudden return of pain
- Device not responding to the remote or programming
- Warning signals from the device during charging
- Changes in sensation at the stimulation site
If you experience these symptoms, contact your pain management specialist promptly for evaluation.
Maximizing the Lifespan of Your Spinal Cord Stimulator
Dr. Jordan Sudberg offers these tips for patients to extend their SCS lifespan:
- Follow manufacturer and doctor instructions on charging and usage.
- Attend all scheduled follow-up appointments to monitor device function.
- Report any new pain, discomfort, or changes immediately.
- Avoid trauma or injuries to the implant site.
- Maintain a healthy lifestyle to support overall device function.
Final Thoughts
Spinal cord stimulators can be life-changing for patients with chronic pain, but understanding device longevity is crucial to managing expectations.
With advancements in rechargeable technology, many patients now enjoy 7 to 10 years or more of reliable pain relief before considering replacement. And with proper care, ongoing support from specialists like Jordan Sudberg, and prompt attention to any issues, the benefits of spinal cord stimulation can extend well into the future.
If you or a loved one are considering an SCS or currently living with one, knowing what to expect can empower you to take control of your pain management journey.
