Chronic pain affects daily movement, sleep, and quality of life. For patients who have tried medication, physical therapy, or surgery without lasting results, spinal cord stimulation offers another option. This treatment uses a small implanted device to deliver mild electrical pulses to the spinal cord, and these pulses interrupt pain signals before they reach the brain, offering relief for people with chronic pain. Here is more information on this treatment option:
What Is Spinal Cord Stimulation?
Spinal cord stimulation is a specialized medical therapy, and it helps treat severe pain. The device consists of a pulse generator and thin wire leads. An interventional radiologist implants the small device under the skin, where it sends electrical currents to specific spinal nerves.
The technology relies on a sophisticated understanding of human anatomy. Thin wires rest in the epidural space, and they connect directly to the pulse generator. Since the system functions as a closed circuit, it delivers precise electrical currents to the targeted nerves.
How Does It Work?
The neurostimulator connects to thin wires called leads, which are placed in the epidural space surrounding the spinal cord. When the device sends electrical pulses through these leads, they interfere with the pain messages traveling toward the brain. Instead of feeling sharp or aching pain, patients may notice a mild tingling sensation or no sensation at all. Patients control the device with a handheld remote. They can adjust the stimulation intensity based on their discomfort level, and this level of control allows for personalized pain relief throughout the day.
What Are Its Uses?
Physicians recommend this intervention for patients experiencing persistent pain conditions that do not respond to physical therapy or oral medication. It treats chronic back pain, especially nerve pain that lingers after spine surgery. Medical professionals may also prescribe this therapy for other complex nerve conditions, including:
- Failed back surgery syndrome
- Complex regional pain syndrome
- Arachnoiditis and peripheral neuropathy
What Does the Process Involve?
The process may begin with a trial period before any permanent device is placed. During the trial, the physician inserts temporary leads near the spinal cord, and they connect them to an external generator worn outside the body. This trial usually helps patients assess how well the stimulation reduces their pain. If the trial provides relief, the next step is implantation of a permanent device.
During the permanent procedure, an interventional radiologist places the leads and a small generator beneath the skin. The procedure is minimally invasive, and it is performed under anesthesia. Patients may return home the same day, enabling them to resume light activity. The care team will provide detailed aftercare instructions to support healing.
What Are the Benefits?
Spinal cord stimulation offers several advantages for patients managing chronic pain. The therapy can reduce reliance on pain medication, including opioids, which carry risks of dependence and side effects. Since the trial period comes first, patients can test the treatment before committing to a permanent implant. Patients may report improved sleep, greater mobility, and a return to activities they had set aside. The device is also adjustable, so it can be turned off if needed.
Consult an Interventional Radiologist
Spinal cord stimulation gives patients with chronic pain an adjustable option when other treatments have not delivered lasting relief. The therapy works by interrupting pain signals, and it can be tailored to your specific needs. An interventional radiologist will evaluate your condition and guide you through each step of the process. If chronic pain limits your daily life, schedule a consultation with an interventional radiologist.
