Everything You Should Know About Spinal Cord Stimulator Trials

Chronic nerve pain can be incredibly disruptive—and frustrating—especially when it lingers long after a spine surgery or injury. Nerves are delicate structures, and even when the spine has been stabilized or repaired, irritated or damaged nerves may continue sending pain signals. This can lead to burning, tingling, shooting, or radiating discomfort that persists despite a patient’s best efforts with medication, physical therapy, or injections.

This is where Spinal Cord Stimulation (SCS) offers real hope. SCS is a proven, long-term treatment option for chronic nerve-related pain, using gentle electrical pulses to interrupt pain signals before they reach the brain. But before moving toward a permanent implant, every patient undergoes an SCS trial—a temporary, reversible test that allows you to “try on” the therapy and see how well it reduces your pain.

At Medici Orthopaedics & Spine, we specialize in minimally invasive, drug-sparing pain solutions. Our approach to SCS trials is rooted in compassionate listening, thoughtful diagnostics, and a deep understanding of nerve pain. We believe you should feel empowered, informed, and supported through every step of your treatment journey.

What Is a Spinal Cord Stimulator and How Does It Work?

Your body communicates with your brain through a vast network of nerves. When everything is functioning properly, these nerves send accurate messages—touch, movement, temperature, and pain.

But when nerves become injured, compressed, or inflamed, they can send constant pain signals, even when no ongoing injury exists. This is why some patients continue to experience severe discomfort long after surgery, injections, or physical therapy. Once a nerve becomes overly sensitive, it may keep “misfiring,” making your body feel pain that doesn’t match the severity of the underlying condition.

How an SCS Device Interrupts Pain Signals

A spinal cord stimulator works by gently influencing the nerves that carry pain messages to the brain. It does this through:

  • Low-level electrical pulses delivered through soft leads placed near the spinal cord
  • Changing how the brain perceives pain, effectively reducing the intensity—or even the presence—of those signals
  • Modern “paraesthesia-free” stimulation, which allows pain relief without the tingling sensations older devices produced

Conditions Most Commonly Treated with SCS

Spinal cord stimulation is especially effective for chronic nerve-based pain conditions such as:

  • Failed Back Surgery Syndrome (FBSS)
  • Chronic radiculopathy (sciatica-like nerve pain that won’t resolve)
  • Peripheral neuropathy
  • CRPS (Complex Regional Pain Syndrome)
  • Post-laminectomy pain
  • Severe nerve irritation from degenerative spine changes

Why an SCS Trial Is Necessary Before Implantation

Ensuring the Therapy Will Work for You

Everyone responds to neurostimulation a little differently. What provides excellent relief for one patient may offer less improvement for another.
The trial allows you to:

  • Experience real pain relief (or lack of it)
  • See how stimulation feels during your normal daily activities
  • Make an informed decision based on results, not guesswork

Safety and Comfort Evaluation

During the trial, you’ll learn how the stimulation feels and how easily it can be adjusted.
You will work with your Medici care team to:

  • Fine-tune stimulation settings
  • Find comfortable programs for different activities
  • Understand how the device adapts to standing, sitting, and movement

Predicting Improvement in Key Areas

The goal of the trial isn’t just pain reduction—it’s improved quality of life. Patients often notice changes in:

  • Daily function (walking farther, standing longer, doing tasks with less discomfort)
  • Sleep quality (fewer pain interruptions at night)
  • Medication reduction (especially neuropathic pain meds)
  • Mobility and lifestyle activities (driving, exercising, household tasks)

The Goal: 50% or Greater Pain Relief

A successful SCS trial typically provides at least 50% reduction in pain—but at Medici, we look beyond numbers.

We evaluate your improvement holistically by asking:

  • Are you moving better?
  • Are you sleeping more comfortably?
  • Are you needing fewer medications?
  • Do you feel more hopeful and capable during everyday life?

What to Expect During the SCS Trial Procedure

Before the Trial

Your journey begins with a thorough evaluation, including:

  • Consultation and diagnostic assessment to confirm whether your pain is nerve-related
  • Reviewing imaging such as MRIs or CT scans
  • Understanding your pain history and what treatments you’ve already tried
  • Clear education about what to expect during the trial and recovery

Step-by-Step Trial Placement

The trial procedure itself takes place in one of our Medici facilities and is typically completed within an hour.

Here’s how it works:

  1. A local anesthetic is used—no large incision needed.
  2. Temporary leads (tiny wires) are inserted through a needle near your spinal cord.
  3. The external stimulator device is secured with medical tape, not implanted.
  4. You go home the same day, ready to begin your trial period.

Trial Duration

Most trials last 3–7 days, giving you enough time to test the therapy during your normal routine.

During this period, you’ll:

  • Track symptoms
  • Test how stimulation feels during different activities
  • Communicate regularly with Medici’s care team for adjustments and guidance

Restrictions During the Trial

To keep the temporary leads secure, you’ll avoid:

  • Bending or twisting at the waist
  • Lifting heavy objects
  • Overly vigorous movements

How Pain Specialists Evaluate Trial Results

Pain Score Comparisons

One of the first steps is comparing your pain levels before the trial to your symptoms during it.

We look at:

  • How much your pain decreased
  • Whether nerve pain symptoms (burning, tingling, shooting sensations) improved
  • The percentage of pain relief you experienced—50% or greater is typically considered successful

Patient Feedback

Your personal experience matters just as much as the data.

We’ll discuss:

  • How your daily activities felt
  • Whether tasks like walking, standing, or sitting were easier
  • How comfortable the stimulation sensation was
  • Whether you felt more relaxed, more mobile, or more hopeful

Activity and Function Tracking

Your specialist also evaluates how your pain responded during real-life situations.

This can include:

  • Walking longer distances
  • Standing or sitting without severe flare-ups
  • Performing household tasks with less effort
  • Showering, dressing, driving—anything you do regularly

Determining Whether Permanent Implantation Is Recommended

If the trial shows promising results, your Medici care team will make a recommendation based on a holistic assessment, including:

  • Overall pain reduction
  • Functional improvement
  • Quality-of-life enhancement
  • Safety and comfort
  • Your personal goals

What Happens If the Trial Is Successful?

Permanent Implantation

If your trial is successful, you may choose to move forward with the permanent spinal cord stimulator implant. This is a minimally invasive outpatient procedure completed through small incisions.

During implantation:

  • The temporary leads used during your trial are replaced with long-term leads positioned precisely where they provide the best pain relief.
  • A small battery-powered generator is implanted under the skin, usually in the upper buttock or abdomen.
  • You can choose between rechargeable and non-rechargeable battery options, depending on your lifestyle preferences and energy needs.

Post-Implant Recovery

Recovery after the permanent implant is typically straightforward.

You can expect:

  • Short downtime, with many patients resuming light activities within a few days
  • A gradual return to normal activity over the following weeks
  • Fine-tuning through device programming sessions, allowing your care team to customize the stimulation settings according to your pain patterns

Expected Long-Term Benefits

For many patients, a successful spinal cord stimulator provides years of meaningful relief. Benefits often include:

  • Consistent reduction in chronic nerve pain
  • Improved mobility and ability to participate in daily activities
  • Significant reduction in medication, particularly neuropathic drugs
  • Better sleep, improved mood, and enhanced quality of life
