Spinal Cord Stimulation: What to Expect

Spinal Cord Stimulation: What to Expect Before, During, and After

Spinal cord stimulation is a minimally invasive therapy that uses a small implanted device to send mild electrical pulses to the spinal cord. These pulses interrupt pain signals before they reach the brain. Most patients first complete a short trial, then receive a permanent implant if the trial reduces their pain by at least 50 percent.

Chronic pain that resists injections, medication, and surgery can feel like a dead end. Spinal cord stimulation (SCS) offers another path. It does not cure the underlying condition. Instead, it changes how your nervous system transmits pain. For the right candidate, that shift can be life-changing.

This guide walks through what to expect at each stage, from candidacy through long-term living with the device.

What Spinal Cord Stimulation Actually Does

A spinal cord stimulator delivers low-level electrical signals to the epidural space near your spinal cord. These signals modify the pain messages traveling to your brain. Some patients feel a gentle tingling called paresthesia. Newer high-frequency systems often produce no sensation at all.

The device has three parts: thin leads (wires), a small generator with a battery, and a handheld controller. You adjust your therapy as your pain changes throughout the day.

SCS works best for neuropathic pain, meaning pain driven by nerve dysfunction rather than a fresh injury. Research published through the National Institutes of Health supports its use for several chronic conditions.

Who Is a Candidate for Spinal Cord Stimulation

Not everyone with chronic pain qualifies. SCS is typically reserved for patients who have already tried conservative treatments without lasting relief. Your provider will review your history, imaging, and prior procedures.

Common conditions treated with SCS include:

  • Failed back surgery syndrome (persistent pain after spine surgery)
  • Complex Regional Pain Syndrome (CRPS)
  • Chronic neuropathic pain in the back, arms, or legs
  • Diabetic peripheral neuropathy
  • Chronic low back pain in patients who have never had surgery

That last group matters. Recent FDA approvals expanded SCS to include patients with non-surgical low back pain. You can read more about non-surgical options in our guide on whether back pain can be treated without surgery.

A psychological screening is often part of candidacy. This step helps confirm that the therapy fits your situation and expectations.

The Trial Period: A Test Drive Before Commitment

Spinal cord stimulation is unusual among pain procedures. You get to test it first. The trial is a low-risk way to see whether the therapy helps before any permanent implant.

During the trial, your physician places temporary leads through a needle into the epidural space. No incision is needed. The leads connect to an external generator you wear on a belt. You then live normally for about five to seven days.

You track your pain, activity, and sleep during this window. A trial is considered successful when pain drops by at least 50 percent. According to the Hospital for Special Surgery, this 50 percent threshold is the standard benchmark for moving forward.

Many patients report meaningful relief during the trial. Published trial success rates often fall between 50 and 80 percent, depending on the condition.

The Permanent Implant Procedure

If your trial succeeds, you can schedule the permanent implant. The procedure is minimally invasive and usually done on an outpatient basis. You go home the same day.

Your physician makes small incisions to place the permanent leads and a generator. The generator sits under the skin, often near the upper buttock or abdomen. Most implants take one to two hours.

Local anesthesia with sedation is common. You may be briefly awakened to confirm the leads cover your pain area correctly. This feedback helps optimize the placement.

Recovery and Healing

Recovery is generally faster than open spine surgery. Still, the leads need time to anchor in place. Your care team will give you activity restrictions for the first several weeks.

Typical early guidance includes:

  • Avoid bending, twisting, lifting, and reaching overhead
  • Keep incision sites clean and dry
  • Limit raising your arms above shoulder height
  • Follow your provider’s timeline for returning to work

Most soreness fades within a couple of weeks. Full healing and lead stabilization can take six to eight weeks. Your provider will fine-tune your stimulation settings during follow-up visits.

Living With a Spinal Cord Stimulator

Once healed, you control your therapy with a handheld remote. You can increase or decrease stimulation, switch programs, and turn the device off when you do not need it.

Battery type matters. Rechargeable systems require periodic charging. Non-rechargeable batteries last several years and are later replaced through a minor procedure. A 2019 FDA-approved low-dose system carries a non-rechargeable battery rated for up to ten years.

Long-term studies show durable results for many patients. One multicenter study tracking high-frequency stimulation reported sustained back and leg pain relief, reduced opioid use, and better sleep at 24 months.

SCS does not work for everyone, and effects can lessen over time. Honest expectations and steady follow-up care produce the best outcomes.

Frequently Asked Questions

Does a spinal cord stimulator get rid of all pain?

No device eliminates all pain for every patient. The goal is meaningful reduction, typically 50 percent or more, along with better function and less reliance on medication. Many patients regain activities they had given up.

Is the implant procedure painful?

The procedure uses local anesthesia and sedation, so you should feel little during it. Mild soreness at the incision sites is normal afterward and usually resolves within two weeks.

Can I have an MRI with a spinal cord stimulator?

Many modern systems are MRI-conditional, meaning scans are safe under specific settings. Tell every imaging provider that you have an implant, and carry your device identification card.

How long do the leads and generator last?

Leads can last many years when properly placed. Generator batteries vary: rechargeable units last longer between replacements, while non-rechargeable batteries are swapped through a minor outpatient procedure every several years.

What happens if the therapy stops working?

Stimulation settings can often be reprogrammed to restore relief. If results fade significantly, your physician can evaluate the leads, adjust programming, or discuss other treatment options.
