SPRINT Peripheral Nerve Stimulation for Back Pain: Can 60 Days Make a Lasting Difference?

Living with chronic lower back pain can make even ordinary activities feel exhausting. Getting out of bed, driving to work, standing in the kitchen, or sitting through a family dinner may become uncomfortable. For some people, the pain continues despite months of physical therapy, medications, injections, or other treatments.

When conventional treatments fail to provide lasting improvement, the next step is not always surgery. One option attracting increasing attention is SPRINT Peripheral Nerve Stimulation, a minimally invasive treatment that uses gentle electrical pulses to influence how pain signals are processed.

Unlike traditional implanted pain stimulation systems, SPRINT Peripheral Nerve Stimulation is designed to be temporary. The treatment typically lasts up to 60 days, after which the small stimulation leads are removed. The aim is to achieve pain relief that may continue after the treatment has ended.

That raises several important questions. How can a temporary device help someone with years of back pain? Does it work for all types of lower back pain? What happens during the procedure, and how likely is it to provide meaningful relief?

Understanding the treatment, its limitations, and the available clinical evidence can help patients decide whether it is worth discussing with a pain management specialist.

SPRINT Peripheral Nerve Stimulation is a temporary electrical stimulation treatment used to manage certain types of persistent pain. It involves placing one or more extremely thin, flexible leads near targeted peripheral nerves that contribute to pain.

These leads connect to a small external pulse generator that delivers controlled electrical impulses to the nerves.

Peripheral nerves carry information between the spinal cord, brain, muscles, and other parts of the body. When pain becomes chronic, the nervous system can develop changes that increase sensitivity to pain signals, even when the original injury has healed or the underlying physical problem has remained relatively stable.

Peripheral nerve stimulation attempts to influence this altered signaling.

The SPRINT system has received clearance from the United States Food and Drug Administration for specified pain-management uses. Its temporary treatment period distinguishes it from systems requiring permanently implanted pulse generators. ^[1]

For chronic lower back pain, the procedure commonly targets the lumbar medial branch nerves. These small nerves are associated with structures in the lower back and supply the multifidus muscles, which play an important role in spinal stability.

The treatment does not remove damaged discs, reverse spinal arthritis, or repair structural abnormalities. Instead, it aims to reduce pain by changing how the nervous system responds to signals coming from the painful region.

The underlying principle is called neuromodulation, which means using targeted stimulation to influence nervous system activity.

Pain is not simply a message traveling from an injured body part to the brain. The spinal cord and brain constantly interpret incoming signals, and this process can change when pain persists for months or years.

In chronic lower back pain, the nervous system may become more responsive to sensations that would not normally produce significant discomfort.

SPRINT Peripheral Nerve Stimulation delivers electrical impulses near selected nerves in an effort to influence these processes.

The lumbar medial branch nerves are small branches of the spinal nerves located near the back of the spine.

They have an important relationship with the facet joints and the multifidus muscles. The facet joints help guide spinal movement, while the multifidus muscles contribute to stability and controlled motion.

During treatment, a physician places the stimulation leads near these nerves, typically using ultrasound or fluoroscopic imaging to guide placement.

Electrical stimulation can activate sensory nerve fibers and produce a comfortable sensation in the painful area. Depending on the treatment settings and target, patients may also experience mild muscle activation.

The goal is not to damage the nerve or permanently block its function.

One explanation for the potential long-term benefits of peripheral nerve stimulation involves neuroplasticity.

Neuroplasticity refers to the nervous system’s ability to change its activity and connections in response to repeated experiences.

When someone experiences chronic pain, the nervous system may become increasingly sensitive. Repeated electrical stimulation may help modify these patterns by providing different sensory information to the brain and spinal cord.

Researchers believe these changes could partly explain why some patients continue to experience relief after the stimulation leads are removed. However, the precise mechanisms behind prolonged pain improvement are still being investigated. ^[2]

This distinction matters because SPRINT Peripheral Nerve Stimulation is not simply intended to suppress pain while a device is switched on. The treatment is designed to create an opportunity for improvement that may extend beyond the 60-day stimulation period.

Not everyone with lower back pain is a suitable candidate for peripheral nerve stimulation.

A pain management specialist must first determine whether the patient’s symptoms, medical history, previous treatments, and examination findings support the use of this therapy.

Chronic lower back pain generally refers to pain that persists for more than three months.

Patients considered for SPRINT Peripheral Nerve Stimulation often experience persistent pain centered in the lower back, sometimes described as axial lower back pain.

This pain may worsen with prolonged sitting, standing, walking, bending, or other everyday activities.

It may be associated with degenerative spinal changes, facet-related pain, or other musculoskeletal conditions. However, identifying an abnormality on imaging does not automatically establish that peripheral nerve stimulation will be appropriate.

Clinical studies of lumbar medial branch stimulation have commonly included patients with chronic axial lower back pain who have not achieved sufficient improvement with nonsurgical treatments. ^[3]

SPRINT Peripheral Nerve Stimulation may be considered when conventional treatments have failed to produce sufficient relief.

These treatments may include:

• Physical therapy and supervised exercise programs.
• Non-opioid pain medications and anti-inflammatory medications.
• Home exercise, stretching, and activity modification.
• Spinal injections or other interventional pain procedures.
• Multidisciplinary pain rehabilitation.

Some patients may have experienced only temporary relief from injections. Others may have difficulty tolerating medications or may prefer to avoid prolonged medication use.

Failure of every available treatment is not necessarily required. The decision depends on the clinical circumstances, the severity of pain, and applicable treatment guidelines or insurance policies.

People considering radiofrequency ablation, permanent neurostimulation, or surgery may wish to discuss temporary peripheral nerve stimulation with their physician.

The treatment does not permanently destroy nerves and does not require an implanted battery.

However, it should not replace necessary surgery when an urgent or clearly correctable neurological or structural problem is responsible for the symptoms.

SPRINT Peripheral Nerve Stimulation may not be suitable for patients who have:

• Certain implanted cardiac devices, including pacemakers or defibrillators.
• Deep brain stimulation systems or potentially interacting implanted neurostimulators.
• An allergy to the adhesives used with the system.
• An active infection at the proposed lead placement site.
• A medical condition that makes the procedure or lead care unsafe.
• A need for magnetic resonance imaging while the complete stimulation system remains in place.

The device has specific manufacturer-listed contraindications. Patients should disclose all implanted devices, allergies, medications, and planned imaging studies before treatment. ^[4]

Patients with significant leg weakness, progressive neurological symptoms, or other evidence of serious spinal disease may require additional evaluation rather than proceeding directly to peripheral nerve stimulation.

This is an important distinction for people researching SPRINT treatment for back pain.

Not all lower back pain originates from the same structures.

Axial lower back pain primarily affects the lower back itself. Sciatica, on the other hand, commonly involves pain radiating into the buttock or leg because of irritation or compression of a spinal nerve root.

A herniated lumbar disc can sometimes cause this nerve irritation, although not every disc herniation produces symptoms.

The strongest clinical evidence specifically involving lumbar medial branch peripheral nerve stimulation largely concerns chronic axial lower back pain rather than classic sciatica caused by nerve root compression.

This does not mean peripheral nerve stimulation can never be considered for neuropathic pain conditions. Different peripheral nerves may be targeted for different problems.

However, patients with severe radiating leg pain, numbness, weakness, or suspected spinal nerve compression should undergo a careful evaluation to identify the source of their symptoms.

SPRINT Peripheral Nerve Stimulation does not physically decompress a pinched spinal nerve or remove a herniated disc.

The treatment is typically performed as an outpatient procedure, often with local anesthesia.

The exact approach depends on the patient’s anatomy, the nerves being targeted, and the physician’s technique.

Before the procedure, the physician reviews the patient’s symptoms, previous treatments, examination findings, and relevant imaging.

For chronic lower back pain, the lumbar medial branch nerves are common stimulation targets.

Ultrasound or fluoroscopy may be used to identify anatomical landmarks and guide accurate placement.

After the skin is cleaned and local anesthetic is administered, the physician introduces a thin lead through a needle near the selected nerve.

The procedure generally does not require a traditional surgical incision.

Depending on the pain pattern and treatment plan, one or more leads may be placed.

The physician may test the stimulation during placement to confirm that the targeted region is being reached and that the sensation is tolerable.

The lead is connected to a small wearable pulse generator located outside the body.

This battery-powered device delivers the electrical impulses responsible for stimulation.

Patients receive instructions on adjusting stimulation levels, caring for the lead insertion site, and protecting the system during daily activities.

The stimulation should generally feel comfortable rather than painful.

Once the system is operating correctly, the patient returns home with instructions for using it over the prescribed treatment period.

The physician determines how frequently and for how long stimulation should be delivered each day.

Follow-up appointments help monitor comfort, skin condition, device function, and treatment response.

Unlike permanent spinal cord stimulation, the SPRINT procedure does not require implantation of a long-term battery or pulse generator. ^[5]

One common concern is whether electrical stimulation itself is painful.

Most patients are expected to experience a mild tingling, tapping, or other comfortable stimulation sensation in the targeted area. The exact feeling varies according to lead placement and device settings.

A sensation of mild muscle activation may also occur.

The treatment should not involve repeated painful electrical shocks. If stimulation becomes uncomfortable, patients should follow their physician’s instructions for adjusting the device and contact the treatment team if the problem persists.

Some people notice improvement relatively early, while others experience more gradual changes during several weeks of treatment.

A lack of immediate pain relief does not necessarily indicate failure, but persistent worsening or new symptoms should be discussed with the treating clinician.

Many people can continue a substantial portion of their normal activities during the 60-day treatment period, although temporary restrictions are necessary.

Activity around the lead placement area is generally limited during the first week to reduce the risk of dislodging the lead.

After this initial period, patients may gradually resume many everyday activities according to their physician’s instructions.

Activities involving repeated bending, twisting, heavy lifting, or excessive movement around the insertion site may need to be modified.

Patients must also follow specific instructions regarding bathing, dressing changes, and care of the external components.

For someone whose chronic back pain has prevented regular walking or exercise, improving mobility may become an important part of recovery.

However, reduced pain should not be interpreted as permission to immediately resume strenuous activities. Gradual conditioning remains important, particularly after months or years of reduced physical activity. ^[6]

The effectiveness of SPRINT Peripheral Nerve Stimulation is one of the most important questions for patients considering the procedure.

Recent clinical research provides encouraging evidence that temporary peripheral nerve stimulation can reduce chronic lower back pain and improve physical function in selected patients.

However, the results should be interpreted carefully. Not everyone experiences substantial relief, and successful outcomes depend on factors such as appropriate patient selection, lead placement, treatment adherence, and individual responses.

A multicenter randomized clinical trial compared 60-day peripheral nerve stimulation with physician-directed usual care involving conventional pain management treatments.

The study included 230 patients with chronic lower back pain who were randomized into two treatment groups.

At three months after treatment began, 55% of evaluable patients in the peripheral nerve stimulation group achieved at least a 50% reduction in average lower back pain, compared with 26% in the usual-care group.

Patients receiving peripheral nerve stimulation also demonstrated greater improvement in measures of disability, pain interference, and quality of life. Benefits were observed through six months of follow-up. ^[7]

These findings suggest that temporary peripheral nerve stimulation may provide meaningful benefits for appropriately selected patients whose chronic lower back pain has not responded adequately to other treatments.

Nevertheless, a 50% reduction in pain is not the same as complete pain elimination. Some patients improve substantially, others experience only partial relief, and some may not respond.

Pain scores are useful, but they do not always capture how much chronic lower back pain affects someone’s life.

A person may consider treatment successful if they can:

• Walk longer distances without frequent rest breaks.
• Sit through meals or meetings more comfortably.
• Return to household activities.
• Sleep with fewer pain-related interruptions.
• Participate more consistently in exercise or rehabilitation.
• Reduce reliance on certain pain medications under medical supervision.

Research suggests that improvements following peripheral nerve stimulation can extend beyond pain intensity to include disability, daily activity interference, and overall quality of life. ^[7]

For many patients, these practical improvements may be as meaningful as changes in numerical pain ratings.

Perhaps the most unusual feature of SPRINT Peripheral Nerve Stimulation is that the device is removed after a relatively short period, yet pain relief may continue.

Patients naturally wonder what happens when the stimulation stops.

Will the pain immediately return? Will the improvement gradually disappear? Could the benefits last for years?

The answer varies.

The SPRINT system is intended for a temporary treatment period of up to 60 days.

After treatment, the physician removes the leads, usually during an office visit.

There is no permanently implanted pulse generator left behind.

Some patients continue to experience reduced pain after removal, which may be related to changes in nervous system processing during the stimulation period.

A prospective multicenter study found that many patients experienced clinically meaningful improvements in pain intensity, disability, or pain interference throughout follow-up extending to 14 months from the beginning of treatment.

At the 14-month assessment, 77% of evaluated participants demonstrated clinically meaningful improvement in at least one of these three outcome measures. ^[8]

Importantly, this combined outcome does not mean that 77% of all patients became pain-free.

Longer-term research has examined whether improvements can persist well beyond the initial treatment period.

A published follow-up study evaluated patients from an earlier clinical trial an average of 4.7 years after peripheral nerve stimulation was initiated.

Among 23 patients who completed the long-term survey, approximately 65% reported sustained, clinically meaningful lower back pain relief compared with their pretreatment condition.

The study also reported that many surveyed patients had not proceeded to treatments such as radiofrequency ablation, permanent neurostimulation, or lumbar surgery. ^[9]

These findings are encouraging, but there is an important limitation: the long-term survey involved a small, selected group of previous treatment responders. It cannot establish that the same proportion of all patients receiving SPRINT will experience relief for several years.

Long-term improvement is possible, but it should not be considered guaranteed.

Lead removal is generally less involved than the original placement procedure.

The clinician carefully withdraws the temporary leads and examines the insertion site.

Patients are usually given instructions for caring for the area afterward.

Because the treatment is temporary, there is no requirement for routine battery replacement or future surgery solely to remove a permanent stimulation device.

Some patients continue to improve after treatment, while others may notice a gradual return of symptoms.

If pain returns, the physician may reassess the diagnosis and consider physical rehabilitation, medication adjustments, targeted injections, or other pain management procedures.

Whether repeating peripheral nerve stimulation is appropriate depends on the individual patient’s response, clinical findings, and treatment circumstances.

Patients should not assume that repeated 60-day treatment courses will produce the same outcome.

Although SPRINT Peripheral Nerve Stimulation is considered minimally invasive, it is not completely risk-free.

Understanding possible complications is essential before agreeing to treatment.

Skin irritation is among the most frequently reported device-related side effects.

The skin around the dressing or external components may become red, itchy, or uncomfortable.

Some patients may develop mild inflammation or blistering.

People with known adhesive allergies should inform their physician before treatment because adhesive sensitivity is a listed contraindication for the system.

Because a lead passes through the skin, infection is a potential complication.

Reported commercial-use infection rates have been approximately 1% to 2%, according to manufacturer safety information. ^[4]

Signs that may indicate infection include increasing redness, warmth, swelling, drainage, fever, or worsening pain around the insertion site.

Patients experiencing these symptoms should contact their treatment team promptly.

The thin stimulation lead may move, become dislodged, or break.

This can interfere with treatment and may require assessment by the physician.

Occasionally, a small lead fragment may remain beneath the skin after removal.

This is particularly important when considering future magnetic resonance imaging.

The complete SPRINT Peripheral Nerve Stimulation system is classified as unsafe for magnetic resonance imaging.

Patients must not undergo magnetic resonance imaging while the system remains in place.

If imaging becomes necessary, the treating physician must arrange removal of the system before the scan.

If a lead fragment remains under the skin, magnetic resonance imaging may still be possible under specific manufacturer-defined conditions. These conditions must be verified before scanning. ^[4]

Overall, serious device-related complications have been uncommon in published clinical studies, but individual risks require discussion with the treating physician.

Patients with persistent lower back pain may encounter both peripheral nerve stimulation and radiofrequency ablation when discussing interventional treatment options.

Although both procedures can involve the lumbar medial branch nerves, they work differently.

Radiofrequency ablation uses heat generated by radiofrequency energy to create a controlled lesion in a targeted nerve.

For appropriately selected patients with facet joint-related pain, interrupting pain transmission through these nerves may provide relief.

The benefits can last for months, although the nerves may regenerate and pain can return.

SPRINT Peripheral Nerve Stimulation does not rely on intentionally destroying or ablating nerve tissue.

Instead, it uses temporary electrical stimulation to influence nerve signaling and pain processing.

Another important distinction is the treatment duration. Radiofrequency ablation is typically a single procedure, whereas SPRINT stimulation continues over an extended period of up to 60 days.

Neither procedure is universally superior.

Radiofrequency ablation may be appropriate for patients with confirmed facet-mediated pain, while peripheral nerve stimulation may be considered in a broader range of selected chronic axial lower back pain presentations.

The decision should depend on the underlying pain mechanism, previous response to diagnostic procedures, and the available evidence for the individual’s condition.

Spinal cord stimulation is another treatment used for selected chronic pain conditions.

However, it differs from peripheral nerve stimulation in several important ways.

Spinal cord stimulation typically involves placing electrodes near the spinal cord within the epidural space. Many systems require implantation of a pulse generator and may be used for prolonged periods.

SPRINT Peripheral Nerve Stimulation targets peripheral nerves outside the spinal cord and uses an external pulse generator during a temporary treatment course.

Traditional spinal cord stimulation may be considered for certain patients with persistent neuropathic pain, including some forms of pain following spine surgery.

SPRINT lumbar medial branch stimulation has a growing evidence base specifically for chronic axial lower back pain.

The best option depends on the location and cause of pain, neurological findings, previous surgeries, and overall treatment goals.

SPRINT Peripheral Nerve Stimulation may help some patients manage persistent back pain without proceeding to more invasive interventions.

However, it is not a replacement for every type of spinal surgery.

Patients with severe spinal instability, progressive neurological deficits, certain forms of nerve compression, or other surgically treatable conditions may require a different approach.

For example, someone with progressive leg weakness caused by significant nerve compression should not rely on peripheral nerve stimulation as a substitute for appropriate spinal evaluation.

Likewise, new bladder or bowel dysfunction, saddle numbness, or rapidly worsening neurological symptoms require urgent medical assessment.

For individuals whose main problem is chronic pain without a condition requiring urgent surgery, peripheral nerve stimulation may be one of several reasonable alternatives to explore.

Coverage for SPRINT Peripheral Nerve Stimulation varies depending on the insurance provider, medical necessity criteria, geographic location, and applicable coverage policies.

Some patients may obtain coverage when the treatment is considered medically necessary, while others may encounter prior authorization requirements or coverage denials.

Medicare coverage is not automatically guaranteed simply because a device has received regulatory clearance.

Patients should ask their physician’s billing team to verify:

• Whether temporary peripheral nerve stimulation is covered under their policy.
• What documentation is needed to establish medical necessity.
• Whether prior authorization is required.
• What deductible, coinsurance, or other out-of-pocket costs may apply.
• Whether the procedure and associated services are covered by the treating provider’s network.

Obtaining written confirmation of benefits before scheduling treatment can help reduce unexpected expenses.

A consultation with an interventional pain management physician is an opportunity to determine whether peripheral nerve stimulation is appropriate for the patient’s specific symptoms.

It helps to bring a complete list of previous treatments, including medications, physical therapy, injections, and any spinal procedures.

Previous imaging studies may also be relevant.

The physician will generally want to know where the pain occurs, how long it has persisted, what activities worsen it, whether symptoms extend into the legs, and how much pain interferes with daily function.

Patients should also disclose any implanted medical devices, blood-thinning medications, allergies, infections, or upcoming imaging procedures.

Useful questions include whether the lumbar medial branch nerves are appropriate targets, what degree of improvement is realistic, how the stimulation schedule will work, and what happens if the treatment does not help.

A clear discussion of expected benefits and limitations is especially important because successful treatment may mean meaningful improvement rather than complete disappearance of pain.

The lead placement procedure is generally performed using local anesthesia, although some temporary discomfort may occur. During treatment, patients typically feel mild tingling or other stimulation sensations rather than pain. Uncomfortable stimulation should be reported to the treating physician.

Procedure duration varies depending on the number of leads being placed, the target nerves, and the complexity of the procedure. It is usually performed in an outpatient setting, allowing patients to return home the same day.

SPRINT Peripheral Nerve Stimulation should not be considered a guaranteed permanent cure. Some patients experience substantial and sustained improvement, while others obtain partial relief or no meaningful benefit. The treatment does not reverse structural problems such as degenerative disc disease or spinal arthritis.

Some patients report improvement shortly after treatment begins, while others notice changes gradually over several weeks. The response varies, and immediate pain relief is not necessary for the treatment to ultimately be beneficial.

Peripheral nerve stimulation may be considered in selected patients who continue to experience back pain after spinal surgery. However, the physician must first determine the likely source of the persistent pain and whether the nerves targeted by SPRINT are appropriate. Patients with ongoing nerve root compression or other postoperative complications may require different treatments.

The treatments have different mechanisms. Steroid injections aim to reduce inflammation in targeted tissues, while peripheral nerve stimulation influences nerve signaling and pain processing. Their relative effectiveness depends on the source of pain, and there is insufficient evidence to conclude that one treatment is universally better for all patients.

Travel may be possible, provided the lead insertion site is protected and patients can follow their stimulation and dressing-care instructions. Before planning a long journey or flight, patients should ask their treating physician about movement restrictions, device management, and travel-related precautions. They should also keep their device documentation available when traveling.

If the treatment provides little or no improvement, the physician may reassess the pain diagnosis, stimulation settings, lead positioning, and treatment adherence. Further treatment may involve physical rehabilitation, medication management, injections, radiofrequency ablation, or other interventions depending on the underlying condition.

Chronic lower back pain rarely has a simple solution. Even when imaging identifies degenerative changes or other abnormalities, treating the visible structural problem does not always eliminate pain.

SPRINT Peripheral Nerve Stimulation offers a different approach by targeting the nervous system rather than relying exclusively on medications, injections, or structural interventions.

Its most appealing feature is the possibility of continued improvement after a temporary, 60-day treatment period. Clinical studies suggest that a meaningful proportion of appropriately selected patients experience reductions in pain and improvements in everyday function.

At the same time, patients should approach the treatment with realistic expectations. It does not correct every cause of back pain, it is not suitable for everyone, and long-lasting relief cannot be promised.

For someone who has spent months or years struggling with persistent lower back pain despite conservative treatment, a consultation with an experienced pain management specialist may help determine whether temporary peripheral nerve stimulation is a reasonable next step.

The goal is not necessarily to eliminate every sensation of discomfort. For many people, being able to walk farther, sleep better, resume meaningful activities, and live with less interference from pain would already represent a substantial improvement.
