TENS therapy in fibromyalgia

Key Takeaways

  • Peripheral nerve stimulation (PNS) is a minimally invasive option for people living with chronic pain that has not improved with traditional treatments.
  • PNS is highly effective for localized pain in areas like the shoulder, knee, and hip — even when the pain does not “feel” like classic nerve pain.
  • Pain clinics treat much more than spine conditions. Peripheral nerve stimulation can target pain in nearly any anatomic region.
  • This therapy does not rely on an implanted battery and preserves normal movement and sensation.
  • A short outpatient trial allows patients to experience real-world pain relief before deciding on long-term treatment.

Rethinking “Nerve Pain”: It’s Not What Most People Expect

When many people hear the term nerve pain, they imagine sharp, burning, tingling, or electric sensations. While those symptoms can occur, nerve-related pain is often far less obvious.

In reality, all pain signals travel through nerves. Nerves are the body’s conductors of pain, whether the source is inflammation, arthritis, joint degeneration, surgical trauma, or soft tissue injury. Sometimes the nerve itself is irritated. Other times, the nerve is simply transmitting pain from another structure.

That means:

  • Pain is not always sharp
  • Pain is not always burning
  • Pain is not always tingling
  • Pain may feel dull, aching, throbbing, or deep

Yet it may still respond exceptionally well to peripheral nerve stimulation.

This is especially important for referring providers and patients to understand:
Peripheral nerve stimulation is not limited to classic “neuropathy.”

Pain Clinics Treat More Than Spine Conditions

Another common misconception is that pain clinics only treat back and neck problems. While spine conditions are common, modern interventional pain practices treat pain throughout the entire body.

Peripheral nerve stimulation is successfully used for:

  • Chronic shoulder pain
  • Chronic knee pain
  • Chronic hip pain
  • Post-surgical joint pain
  • Limb pain
  • Certain types of headache and facial pain

If there is a nerve transmitting pain from a specific area, that nerve can potentially be targeted.

Understanding Who Benefits Most From Peripheral Nerve Stimulation

Peripheral nerve stimulation is designed for patients whose pain has become persistent, disruptive, and resistant to conservative care.

Many patients exploring this therapy have already tried:

  • Physical therapy
  • Anti-inflammatory medications
  • Nerve medications
  • Steroid injections
  • Joint injections

When those options fail to provide lasting relief, PNS may be the next appropriate step.

The therapy works best when pain can be localized to a specific anatomic region and traced to one or more peripheral nerves.

At Grand Rapids Pain, peripheral nerve stimulation is offered as part of a comprehensive, individualized approach to chronic pain management.

Conditions That Respond Well to Peripheral Nerve Stimulation

Chronic Shoulder Pain

Chronic shoulder pain is one of the most successful and well-established uses of peripheral nerve stimulation. Whether pain persists after surgery or surgery is not desired, PNS can significantly reduce shoulder pain without limiting strength or movement.

Chronic Knee Pain

Persistent knee pain, even after joint procedures or conservative treatment,  may respond extremely well to nerve stimulation. Targeting knee-related nerves allows for focused relief while preserving mobility.

Hip and Joint-Related Pain

Patients with lingering hip pain, including pain after joint replacement, may benefit from PNS when the pain signal continues despite mechanical correction of the joint.

Other Localized Pain Conditions

Peripheral nerve stimulation may also help:

  • Arm or leg pain
  • Post-surgical pain in a specific region
  • Certain facial pain conditions
  • Chronic headaches related to peripheral nerve irritation

The key is localization. When pain can be mapped to a specific nerve pathway, stimulation can often help.

Health and Lifestyle Factors That Influence Candidacy

Being a good candidate involves more than just where pain is located.

Factors That Support Good Outcomes

  • Pain localized to a specific area
  • Chronic symptoms lasting several months or longer
  • Limited benefit from medications, therapy, or injections
  • Desire to reduce reliance on pain medications
  • Willingness to participate in a short outpatient trial

Factors That May Require Additional Evaluation

  • Widespread, poorly defined pain
  • Active infection near the treatment site
  • Certain untreated medical conditions affecting healing

Because peripheral nerve stimulation is minimally invasive, many patients who are not surgical candidates may still qualify.

How Peripheral Nerve Stimulation Differs From External Nerve Therapies

Patients sometimes compare PNS to TENS units. While both use electrical signals, they function very differently.

FeaturePeripheral Nerve StimulationExternal Nerve Stimulation (TENS)
TargetSpecific peripheral nerveSkin-level nerve endings
DepthDirect nerve modulationSurface-level stimulation
Duration of ReliefHours to daysMinutes to hours
ImplantTiny internal receiver, no batteryExternal pads only
MovementFully preservedFully preserved

Peripheral nerve stimulation provides deeper, more consistent modulation because it works directly at the nerve responsible for transmitting pain.

What to Expect During the Evaluation Process

Evaluation begins with a detailed assessment of pain location, history, prior treatments, and functional goals.

If appropriate, patients may undergo a short outpatient trial.

The Trial Phase

During the trial:

  • Hair-thin receiver wires are placed just beneath the skin near the targeted nerve
  • No large incisions are required
  • Patients use a small external transmitter at home
  • Stimulation is tested during normal daily activities

This allows patients to determine how much relief they experience in real-life conditions.

Determining Success

A successful trial typically includes:

  • 50% or greater pain reduction
  • Improved daily function
  • Reduced need for medications

If successful, permanent placement may be recommended.

What Happens After Permanent Placement

Permanent placement is a brief outpatient procedure, typically completed in under an hour.

Unlike some implanted devices, peripheral nerve stimulation:

  • Does not require a battery implant
  • Does not require battery replacement surgery
  • Remains invisible under the skin
  • Does not restrict movement

After healing, patients often use stimulation only briefly to achieve extended relief.

Long-Term Expectations

Most patients experience sustained improvement in both pain and function. Relief commonly ranges from 50% to 95%, depending on the condition and individual response.

Importantly, choosing PNS does not eliminate other treatment options. Additional procedures or surgery can still be pursued if necessary.

As insurance coverage for repeated nerve blocks becomes less predictable, peripheral nerve stimulation is becoming an increasingly valuable long-term strategy.

Frequently Asked Questions

How do I know if I am a candidate for peripheral nerve stimulation?

You may be a candidate if your pain is localized to a specific region and has not improved with conservative treatments, even if it does not feel like typical nerve pain.

Does peripheral nerve stimulation require a battery implant?

No. The system uses a tiny internal receiver and an external transmitter, eliminating the need for an implanted battery.

Is peripheral nerve stimulation permanent?

The system can remain in place long term, and many patients experience sustained relief.

Will peripheral nerve stimulation limit my activity?

No. Once healed, normal movement and daily activities are fully preserved.
