A spinal cord stimulator (SCS) is an implanted device designed to help manage chronic pain by delivering mild electrical signals to specific nerves in the spinal cord. This electrical stimulation works to disrupt or modify pain signals before they reach the brain, offering relief for individuals whose pain has not responded to other treatments. Living with an SCS requires an understanding of certain permanent restrictions and precautions. These guidelines are important for ensuring both patient safety and the long-term functionality of the implanted device.
Navigating Medical Procedures
Individuals with a spinal cord stimulator must exercise caution with various medical procedures. Magnetic Resonance Imaging (MRI) compatibility is a significant consideration, as the powerful magnetic fields generated by MRI machines can interfere with the SCS. Historically, MRI scans were largely contraindicated due to risks of device damage, lead heating, dislodgement, or uncomfortable sensations. Modern SCS devices are often classified as “MRI Conditional,” meaning they can be safely scanned under specific conditions, such as particular field strengths and by temporarily adjusting or turning off the device. Always inform healthcare providers about the SCS before any imaging or procedure and verify the specific model’s MRI compatibility.
Other medical therapies also pose risks. Diathermy, a treatment using high-frequency electrical currents to generate heat, is generally contraindicated for SCS patients. This energy can transfer through the implanted system, potentially causing tissue damage or severe injury. Therapeutic ultrasound can also interfere with the device, leading to unexpected changes in stimulation or patient injury.
Surgical procedures involving electrocautery require specific precautions. The SCS device should be turned off or placed in “Surgery Mode” during such procedures to prevent interference. Patients must inform their medical and dental care teams about their SCS before any intervention to ensure appropriate safety measures are taken.
Understanding Environmental and Activity Limitations
Living with a spinal cord stimulator involves permanent adjustments to certain environments and physical activities. Strong electromagnetic fields, such as those produced by industrial magnets, large loudspeakers, or power generators, can interfere with the SCS, potentially turning the device off or causing uncomfortable sensations. While most household electronics are safe, be mindful of powerful magnetic sources.
Security screening systems, including airport metal detectors and store anti-theft devices, can detect the implanted SCS. Inform security personnel about the device and present an identification card. This may require temporary deactivation or a manual pat-down to avoid interference or discomfort.
Certain physical activities require permanent modifications to protect the device. Avoid activities involving direct impact to the implant site. Excessive bending, twisting, or heavy lifting can dislodge leads or damage the device. High-impact and contact sports are generally not recommended.
Many can safely engage in low-impact activities like walking, swimming (after healing), and stationary biking. Patients using SCS that produce paresthesia (a tingling sensation) should turn off their device before operating a motorized vehicle or dangerous machinery to avoid distraction from sudden stimulation changes.
Ensuring Long-Term Device Safety
Ensuring the long-term safety and effectiveness of a spinal cord stimulator requires ongoing attention. Always carry SCS identification, such as an implant card or medical alert jewelry. This serves as a crucial identifier for medical and security personnel in emergency situations. This identification typically includes the patient’s name, their doctor’s contact information, and details about the implanted device.
Regular follow-up appointments with the SCS care team are necessary for long-term device management. These appointments monitor device function, assess battery life, and adjust stimulation settings for optimal pain relief.
Proper battery management is another key aspect of long-term care. Rechargeable SCS devices require consistent recharging, daily or weekly depending on usage. Avoid sleeping while charging. Non-rechargeable batteries have a finite lifespan, typically ranging from two to ten years, and will eventually require a surgical replacement procedure. The device alerts when battery is low.
Patients should recognize signs of potential device malfunction or complication and seek prompt medical attention. Signs include inadequate pain relief, abnormal sensations, or physical changes at the implant site (pain, swelling, redness). Lead migration or fracture can also lead to loss of stimulation or altered pain relief. Promptly addressing these issues maintains SCS benefits.
