Peripheral Nerve Stimulation

Peripheral Nerve Stimulation (PNS) is an innovative, minimally invasive treatment used to manage chronic pain by targeting specific peripheral nerves responsible for transmitting pain signals. By delivering mild electrical pulses to these nerves, PNS can effectively reduce pain, improve function, and enhance quality of life. This therapy is particularly beneficial for patients whose pain has not responded to other treatments.

Is Peripheral Nerve Stimulation Right for Me?

What Conditions Does It Treat?

Peripheral Nerve Stimulation is used to address a variety of chronic pain conditions, including:

  • Diabetic Peripheral Neuropathy: Persistent nerve pain in the hands, feet, or legs caused by diabetes.
  • Post-surgical or Post-traumatic Pain: Chronic pain following surgeries or injuries, such as knee replacement or fractures.
  • Complex Regional Pain Syndrome (CRPS): Severe pain and hypersensitivity typically affecting a limb.
  • Peripheral Neuralgia: Pain caused by nerve damage or irritation, often presenting as burning or stabbing sensations.
  • Other localized nerve pain: Pain affecting specific areas, such as the shoulders, arms, or back.

This therapy is particularly effective for patients with localized pain who have only experienced minimal relief from medications or physical therapy.

Who Is a Good Candidate for Peripheral Nerve Stimulation?

Peripheral Nerve Stimulation is best suited for individuals with chronic, localized nerve pain that has not responded well to conventional treatments. Candidates often include those experiencing neuropathic pain, individuals seeking to reduce their reliance on long-term medications such as opioids, and those looking for a minimally invasive option to manage pain without major surgery.

A thorough evaluation, including medical history and imaging studies, helps determine if you are a suitable candidate for PNS.

How Does Peripheral Nerve Stimulation Work to Control My Pain?

PNS involves implanting a small device near the peripheral nerve causing pain. The device delivers electrical impulses to the nerve, disrupting the transmission of pain signals to the brain. This process "modulates" the nerve activity, reducing the intensity of pain and improving overall comfort. Patients often experience significant improvement in their pain levels, mobility, and daily functioning.

Preparing for Treatment

What Should I Expect During Peripheral Nerve Stimulation?

Peripheral Nerve Stimulation typically involves two stages: a trial phase and, if successful, permanent implantation. The procedure begins with the trial phase, where a thin electrode (lead) is inserted near the nerve causing pain. This is done under local anesthesia, with the help of imaging guidance such as fluoroscopy or ultrasound to ensure precise placement. The lead is connected to an external pulse generator, which delivers mild electrical signals to the targeted nerve.

During the trial, which lasts several days, you will evaluate how well the stimulation reduces your pain and whether it improves your daily activities. If the trial is successful, the second phase involves implanting a small permanent device under the skin. This outpatient procedure is done under local or general anesthesia and takes about an hour.

How Long Does the Procedure Take?

The initial trial placement usually takes about 30 to 60 minutes. If the trial is successful, the permanent implantation procedure also takes approximately an hour and is typically performed on an outpatient basis.

After Treatment

How Soon Will I Feel Pain Relief?

Many patients notice immediate pain relief during the trial phase, while others may experience gradual improvement over the following days. Once the permanent device is implanted, pain relief is often sustained and consistent, improving overall function and quality of life.

How Long Does Recovery Take?

Recovery from PNS is generally quick. Patients can resume light activities within a few days but should avoid heavy lifting or strenuous exercise for at least two weeks. Your doctor will provide detailed instructions to ensure optimal recovery and device performance.

Signs to Watch for After Treatment

While complications are rare, it is essential to monitor for any unusual symptoms, such as:

  • Persistent or worsening pain or swelling near the implant site.
  • Redness or signs of infection.
  • Difficulty operating the device.
  • New or worsening neurological symptoms, such as numbness or weakness.

If you experience any of these issues, contact your physician immediately for further evaluation.
