Chronic low back pain is one of the most common causes of long-term disability and reduced quality of life in adults. For many patients, pain persists for months or years despite physical therapy, pain medicine, injections, and activity modification. When conservative treatments fail to provide lasting relief, patients often seek alternatives that address the underlying cause of pain rather than only managing symptoms.
Restorative neurostimulation is a newer, FDA-approved therapy designed for patients with chronic mechanical low back pain associated with dysfunction of the lumbar multifidus muscle. At NJ Spine & Orthopedic, Dr. Johnson S. Ho offers restorative neurostimulation as a minimally invasive treatment option for carefully selected patients who are not candidates for surgery or who wish to avoid surgical intervention.
Understanding Chronic Mechanical Low Back Pain
Chronic low back pain is defined as pain that lasts longer than three months. In many cases, this pain is mechanical, meaning it worsens with movement, prolonged standing, or certain positions and improves with rest. Mechanical low back pain often affects the lumbar spine, which bears much of the body’s weight and plays a central role in movement and stability.
One of the most important stabilizing muscles of the lumbar spine is the deep lumbar multifidus. Loss of control of the multifidus muscle can occur after injury, disc degeneration, or persistent pain. When this muscle becomes inhibited, it may undergo atrophy and be replaced by fatty tissue. This change can often be identified through MRI and is associated with functional lumbar instability.
Over time, impaired multifidus function reduces spine stability, increases stress on spinal joints and surrounding soft tissues, and contributes to ongoing pain and disability.
What Is Restorative Neurostimulation?
Restorative neurostimulation therapy is a form of neuromodulation for back pain that directly targets the nerves responsible for activating the multifidus muscle. Unlike treatments that attempt to block pain signals, restorative neurostimulation aims to restore muscle control and improve spine stability.
The ReActiv8 neurostimulation system is the only FDA-approved implantable device specifically indicated for chronic low back pain associated with multifidus dysfunction. This therapy is considered a new restorative therapy because it focuses on rehabilitation of muscle function rather than masking pain.
Electrical stimulation is delivered in a controlled and scheduled manner to retrain the multifidus muscle. Over time, this stimulation helps override arthrogenic muscle inhibition and restore mechanonociceptive feedback, which supports improved movement and reduced pain.
How Restorative Neurostimulation Fits Into the Chronic Low Back Pain Treatment Timeline
Restorative neurostimulation is not considered a first-line treatment for low back pain. It is typically introduced after patients have completed appropriate conservative care and continue to experience chronic symptoms.
A typical treatment timeline may include:
- Initial evaluation and diagnosis through physical examination and imaging
- Trial of conservative treatments such as physical therapy, activity modification, and pain medication
- Image-guided injections when appropriate
- Reassessment of symptoms and functional limitations
When chronic low back pain persists without a clear surgical indication, restorative neurostimulation may be considered as a next step. This therapy provides an alternative to surgery for patients who have exhausted conservative options but still require targeted intervention to address the underlying cause of pain.
How the ReActiv8 Neurostimulation System Works
The ReActiv8 system consists of an implanted neurostimulation device placed through a minimally invasive outpatient procedure. The leads are carefully placed to stimulate the nerves that activate the multifidus muscle instead of targeting the spinal cord directly.
Key characteristics of the system include:
- Targeted electrical stimulation of the multifidus muscle
- Scheduled therapy sessions rather than continuous stimulation
- Focus on restoring muscle activation and spine stability
Intraoperative measurements and architectural analysis during implantation help confirm accurate lead placement. Therapy is designed to work gradually, and improvements in pain and function often occur over time rather than immediately.
This approach supports durable pain relief therapy by addressing the underlying condition that contributes to chronic mechanical low back pain.
Clinical Evidence Supporting Restorative Neurostimulation
Clinical studies, including randomized controlled trials and real-world outcome data, provide strong clinical evidence for neurostimulation in appropriately selected patients. Research has demonstrated meaningful reductions in pain and disability, along with improvements in physical activity and quality of life.
Reported outcomes commonly include:
- Sustained reduction in chronic low back pain
- Improved functional capacity and mobility
- Reduced reliance on pain medications, including opioids
- Favorable long-term outcomes compared with standard medical management
In addition to pain reduction, restorative neurostimulation has been associated with decreased healthcare utilization and improved patient-reported outcomes.
How Restorative Neurostimulation Differs from Spinal Cord Stimulation
A spinal cord stimulator is another implanted device used for chronic pain, but it functions differently from restorative neurostimulation. Spinal cord stimulation delivers low levels of electrical current to the spinal cord to alter pain signals before they reach the brain.
Spinal cord stimulators typically consist of:
- Thin wires called electrodes placed in the epidural space
- A small battery or generator implanted under the skin
- A remote control that allows patients to adjust stimulation
Spinal cord stimulation is most often used after nonsurgical treatments have failed and is typically focused on pain signal modulation.
Restorative neurostimulation differs in that it targets muscle activation rather than pain pathways. The goal is to improve spine stability and address the underlying cause of pain rather than simply reducing pain perception.
Who Is a Candidate for Restorative Neurostimulation?
Careful patient selection is essential for successful outcomes. Restorative neurostimulation is generally considered for patients who:
- Have chronic low back pain lasting at least six months
- Have mechanical low back pain without a clear surgical target
- Have failed conventional management, including physical therapy and injections
- Do not have severe spinal instability or significant nerve root compression
A thorough physical examination and imaging evaluation help identify multifidus dysfunction and rule out other structural abnormalities that may require different treatment options.

Improving Quality of Life Without Surgery
For patients with refractory chronic low back pain, restorative neurostimulation offers a non-surgical alternative that can improve daily function, reduce discomfort, and support long-term spine stability. By restoring multifidus muscle control, this therapy helps patients move with greater confidence and reduced pain.
NJ Spine & Orthopedic offers restorative neurostimulation as part of a comprehensive spine care approach that includes physical therapy, interventional treatments, and advanced diagnostics.
When to Consider a Consultation
Patients should consider consulting a spine specialist if low back pain persists for months, interferes with physical activity, or does not improve with conservative treatments. Early evaluation helps determine whether restorative neurostimulation or other treatment options are appropriate.
An informed decision begins with understanding the underlying condition and reviewing all available therapies.
