⚡ Patient guide

Spinal Cord Stimulation

A comprehensive patient guide for chronic neuropathic pain

Everything you need to know about SCS — from trial to implant, programming, and daily life with your device. Written in plain language for patients and families.

〰

Leads (Electrodes)

Thin wires placed near the spinal cord in the epidural space. These deliver mild electrical stimulation to reduce how strongly the brain perceives pain.

🔋

Battery (IPG)

A small implantable pulse generator placed under the skin — often in the buttock or flank area. Powers the system.

🎮

Your Remote

A handheld controller that lets you manage your stimulation within safe limits set by your care team.

Most people start with a temporary trial first — and only proceed to permanent implantation if the trial provides meaningful relief. Think of it as a "test drive" before committing.

Indications

What SCS Can Help

SCS is typically considered when pain has not improved with appropriate non-surgical care — medications, physical therapy, injections, and other interventions.

🔙 Persistent Spinal Pain

After back or spine surgery (often called "failed back surgery syndrome" / PSPS).

🔥 CRPS

Complex regional pain syndrome — a chronic pain condition often affecting a limb.

⚡ Neuropathic Pain

Including diabetic neuropathy, post-herpetic neuralgia, phantom limb pain — selected patients.

💡 SCS is best studied for pain with a strong neuropathic component — burning, shooting, electric-like pain, hypersensitivity — rather than pain driven purely by structural instability or active compression.
Am I a candidate?

Who May Be a Good Candidate

You may be a candidate if you:

  • ✓ Have chronic pain that remains function-limiting despite appropriate first-line therapies
  • ✓ Have pain that appears neuropathic in origin (or has a substantial neuropathic component)
  • ✓ Can safely undergo a procedure and commit to follow-up programming visits
  • ✓ Complete psychosocial screening — many consensus guidelines recommend validated screening, including depression screening, as part of best practice

When SCS may not be recommended

  • ✕ Active infection or medical issues that make surgery unsafe
  • ✕ Pain that is unlikely to respond to neuromodulation (depends on diagnosis and pain mechanism — your team will explain)
The SCS process

From Evaluation to Implant

SCS has a unique advantage: you get to try it before committing. The trial phase lets you and your team confirm that stimulation actually helps your pain before permanent implantation.

1

Candidacy Evaluation

Clinic phase

Your team gathers the information needed to determine if SCS is right for your pain pattern.

  • Review of diagnosis, prior treatments, and imaging
  • Goal-setting: what does "success" look like for you?
  • Medication review and optimization plan
  • Psychosocial screening (standard in many programs)
2

Trial Stimulation

Test-drive phase

Temporary leads are placed and connected to an external generator that you wear during the trial — typically 5–7 days.

  • You go home with the temporary system
  • Track pain levels, sleep, and function
  • Confirm meaningful benefit before permanent implant
  • Common success threshold: ~50% pain reduction
3

Permanent Implantation

Therapy phase

If the trial is successful, permanent leads and the battery (IPG) are implanted under the skin.

  • Programming adjusted over time
  • Think of SCS as a therapy that is optimized — not a single setting forever
  • Periodic maintenance and battery monitoring
  • Your pain management team coordinates long-term care
✓

What makes a "successful" trial?

A commonly used definition is approximately 50% pain reduction — ideally paired with improved function, better sleep, or reduced medication burden. Your team will discuss specific goals before the trial begins.

Technology options

Types of Neuromodulation

Your team will recommend a system based on your pain pattern, anatomy, and goals. Here are the main distinctions:

〰

Traditional SCS (Epidural Leads)

The most common approach. Leads are placed in the epidural space along the spinal cord. Used for many neuropathic pain patterns including back and leg pain.

🎯

DRG Stimulation

Targets the dorsal root ganglion — helpful for focal pain distributions in selected patients. Complication types are similar to SCS (pocket pain, lead migration, fracture, infection).

🔋

Rechargeable vs. Non-Rechargeable

Rechargeable systems require regular charging but last longer. Non-rechargeable systems are more convenient day-to-day but need battery replacement when depleted.

⚡

Paresthesia-Based vs. Paresthesia-Free

Some programs use stimulation that feels like tingling; others aim to reduce pain with minimal or no tingling. Device and programming dependent — your team will explain the options.

Setting expectations

What Results Should I Expect?

A realistic goal: meaningful improvement — not zero pain

In carefully selected patients, a substantial subset achieve approximately 50% pain relief. SCS can also help some patients reduce pain medication use and improve daily function, sleep, and quality of life.

Over time, some patients need reprogramming to maintain benefit. A smaller subset may experience reduced benefit or need revision for hardware issues. Your team will discuss realistic expectations for your specific situation.

Daily life

Living with SCS

Practical guidance for day-to-day life with your SCS system — from activity restrictions to travel and medical procedures.

🎮 Remote & Daily Use

You'll receive instructions on safe adjustments, what sensations are expected, and what changes should prompt a call to your team.

🏃 Activity & Healing

After implantation, many programs restrict bending, lifting, stretching, and intense activity for a period while leads stabilize. Your team will specify timelines.

🚗 Driving & Safety

Many major patient resources advise: turn stimulation off before driving or operating machinery and power tools.

✈ Travel & Security

Carry your medical device ID card. Many devices can set off security alarms — show your card, turn stimulation off if needed, and walk through normally.

🧲 MRI & Medical Procedures

MRI rules are device-specific. MRI is not safe with many SCS devices — always tell every provider you have an implant before any imaging. Some procedures (e.g., diathermy) may be unsafe.

🔋 Battery Management

Rechargeable batteries require a regular charging routine. Non-rechargeable batteries will eventually need replacement — an outpatient procedure. Your team will monitor battery status.

Honest discussion

Risks and Complications

All procedures have risks. Understanding them is part of making an informed decision about SCS.

Procedure-Related Risks

  • Infection
  • Bleeding or neurologic injury (rare but important)
  • Headache after dural puncture (uncommon — your team will explain warning signs)

Device-Related Risks

  • Lead migration (leads move out of position), lead fracture, hardware malfunction
  • Pocket discomfort or irritation at the battery site (usually improves; sometimes requires adjustment)
  • Need for reprogramming, revision, or battery replacement over time
A note about infection: Because infection is one of the most consequential complications for implanted neuromodulation systems, expert consensus groups have published best-practice recommendations focused on prevention and management. Your surgical team follows these protocols to minimize risk.
Other options

Alternatives to SCS

⚖

Depending on Your Diagnosis

  • Medication optimization, physical therapy, behavioral pain strategies
  • Injections or ablative pain procedures (case-dependent)
  • Surgical options if pain is driven by a correctable structural cause
  • DRG stimulation in selected focal pain patterns
Common questions

Frequently Asked Questions

Is SCS permanent? Can it be removed?
Yes — SCS hardware can be turned off and can be removed if needed, though removal is another procedure. One of the advantages of the trial phase is that you can confirm benefit before committing to a permanent implant.
Will I feel tingling?
It depends on the type of stimulation. Some SCS modes produce tingling (paresthesia); others aim to reduce pain with minimal or no tingling sensation. Tingling or numbness can also occur as a stimulation side effect in some patients. Your team will explain the options and help find what works best for you.
How do you decide if the trial is "good enough"?
Many programs look for approximately 50% pain reduction, plus meaningful improvement in function, sleep, and/or reduced medication reliance. The definition of success is discussed before the trial begins so you and your team are aligned on goals.
Can I get an MRI?
It depends on your exact system and the MRI protocol. MRI is not safe with many SCS devices — always tell your providers you have an implant and check your device's specific MRI conditions before any scan.
Can I travel and go through airport security?
Yes. Carry your device ID card and follow the manufacturer's instructions for screening. Many devices can set off security alarms — show your card, turn stimulation off, and walk through normally.
Can I drive with SCS on?
Many patient resources recommend turning stimulation off before driving or operating machinery for safety. Your team will provide specific guidance based on your device and your response to stimulation.
