Peripheral nerve stimulation is an option for patients with chronic nerve pain that has not responded adequately to other treatments. This therapy delivers gentle electrical pulses to specific nerves, interrupting pain signals before they reach the brain.
The treatment involves a trial period that allows you to experience the therapy before committing to a permanent implant. This ensures you achieve meaningful benefit before proceeding.
What is Peripheral Nerve Stimulation?
Peripheral nerve stimulation uses a small device to deliver electrical impulses to nerves outside the spinal cord. These impulses modify the way pain signals are transmitted, reducing the perception of pain.
The system includes thin leads placed near the target nerve and a small generator that powers the device. Modern systems are compact and programmable, allowing adjustments to optimize pain relief.
What Does Peripheral Nerve Stimulation Treat?
This therapy treats chronic pain from peripheral nerve injury, nerve entrapment, complex regional pain syndrome, and post surgical nerve pain. It may also help patients with certain types of headache and localized neuropathic pain.
Candidates typically have pain that is well localized, has not responded to conservative treatments, and is not amenable to surgical correction. A thorough evaluation determines whether you may benefit from this therapy.
How Does Peripheral Nerve Stimulation Work?
Electrical stimulation changes how the nervous system processes pain signals. The impulses may create a pleasant tingling sensation or work silently in the background depending on the programming. Either way, the result is reduced pain perception.
The therapy is adjustable. Settings can be modified over time to maintain optimal relief. Because the treatment is reversible, it can be discontinued if circumstances change.
What to Expect During the Procedure
Treatment begins with a trial period lasting several days to two weeks. Temporary leads are placed near the target nerve under local anesthesia and connected to an external generator. You will use the device in your daily life to evaluate effectiveness.
If the trial provides significant relief, a permanent system is implanted during a separate outpatient procedure. The generator is placed under the skin in a convenient location, and the leads are secured near the target nerve.
Recovery Timeline
Following the trial lead placement, you will have some activity restrictions while the temporary leads are in place. Keep the insertion site clean and dry. You will track your pain levels and report back on your experience.
After permanent implantation, most patients return to normal activities within one to two weeks. Dr. Sperzel will provide specific guidance based on the location of your implant. Programming adjustments may be made over time to optimize results.
