What Is Spinal Decompression? Advanced Technology Explained

Spinal decompression therapy is a non-surgical treatment that relieves pressure on spinal discs and nerves through computer-controlled precision traction. 

Unlike traditional traction, which pulls with a constant force, decompression alternates between pulling and releasing to allow the spine to relax and heal naturally.

How Spinal Decompression Works

Computer-Controlled Precision

• Modern spinal decompression systems use advanced computerized sensors to monitor spinal response hundreds of times per second.

These sensors measure muscle tension, patient resistance, and changes in spinal elongation throughout the treatment.

• Real-time monitoring allows the table to automatically adjust the amount of pull and relaxation applied to your spine.

This precision prevents muscle guarding and ensures that the spine gently separates without triggering pain or spasms.

• Each session is customized based on the patient’s body weight, spinal level being treated, and tolerance levels recorded from previous visits.

This individualized control allows for consistent progress across multiple sessions and minimizes the risk of over-stretching or discomfort.

Dr. Jason Crist explains: “The technology behind modern decompression makes it safer and more effective than older traction methods. The table constantly reads how your body responds and adapts in real time to keep the treatment comfortable and productive.”

Intermittent Negative Pressure

• One of the most important differences between decompression and traditional traction is the ability to create intermittent negative pressure inside the spinal discs.

During each pull phase, the decompression table gently separates the vertebrae, reducing pressure inside the disc and creating a mild vacuum effect.

• This vacuum can draw bulging or herniated material back toward the center of the disc, relieving pressure on nearby nerves and improving circulation to the area.

As the disc rehydrates and receives oxygen-rich nutrients, the body can begin natural tissue repair and inflammation reduction.

• Each decompression cycle alternates between gentle pull and rest phases, which stimulates fluid exchange in the spine.

This rhythmic motion helps nourish the discs, improve flexibility, and encourage long-term healing rather than short-term symptom relief.

“That vacuum effect is what makes decompression unique. It is not just stretching; it’s promoting true disc recovery by restoring the spine’s internal balance.” – Dr. Jason Crist

Targeted, Disc-Specific Treatment

• Spinal decompression can be precisely directed to specific spinal segments that show signs of degeneration or herniation.

Before treatment begins, diagnostic evaluation and imaging help determine which discs need the most attention, whether in the cervical, thoracic, or lumbar spine.

• The decompression system can angle the pull to isolate individual discs and apply just the right amount of traction where it is needed most.

This focus allows the therapy to relieve pressure on affected nerves while leaving healthy structures unaffected.

• By treating the exact source of compression rather than the entire spine, decompression therapy supports faster, more efficient healing.

It also helps improve spinal alignment and stability over time, which contributes to better posture and reduced recurrence of pain.

Patient Benefit:
Because decompression targets the true source of pain, many patients notice improvements not only in back comfort but also in leg or arm symptoms caused by pinched nerves.

Dr. Jason Crist explains: “Modern spinal decompression works because it is precise. It creates negative pressure inside the disc, which helps retract bulging material and promote healing.”

Conditions Best Suited for Spinal Decompression

Spinal decompression therapy is designed to relieve pressure on the spinal discs and nerves. It is especially effective for patients dealing with chronic pain caused by disc compression, nerve irritation, or degeneration.

Below are the conditions that tend to respond best to non-surgical spinal decompression.

---

Herniated or Bulging Discs

When a disc herniates or bulges outward, it can press on nearby spinal nerves and cause sharp, radiating pain through the back, neck, arms, or legs.

Decompression gently pulls the vertebrae apart to reduce pressure inside the disc. This allows the herniated material to retract toward its normal position and relieves the nerve irritation that causes pain, numbness, and tingling.

Over time, the increased nutrient flow promoted by decompression helps restore disc height and improve flexibility. 

Many patients with herniated or bulging discs experience significant pain reduction and improved mobility after a complete treatment plan.

Did You Know? Studies have shown that decompression can restore measurable disc space and promote healing in cases of lumbar and cervical disc herniation, helping patients avoid surgery.

Degenerative Disc Disease (DDD)

Degenerative disc disease occurs when spinal discs lose hydration and elasticity over time, often leading to chronic stiffness and dull, aching pain.

As discs lose height, vertebrae compress together and may pinch nerves or create bone spurs.

Spinal decompression counteracts these effects by gently separating the vertebrae and increasing circulation within the discs. 

This process encourages rehydration and slows down further degeneration. Patients often report reduced stiffness, improved posture, and increased spinal flexibility after regular sessions.

“For patients with degenerative disc disease, decompression can help restore the space and movement their spine has lost over the years. 

It’s one of the most natural ways to relieve ongoing pressure and inflammation.” – Dr. Jason Crist 

---

Sciatica and Nerve Compression

Sciatica is one of the most common symptoms treated with decompression therapy. It occurs when the sciatic nerve becomes compressed by a disc herniation or narrowing in the lower spine.
 

Symptoms can include sharp leg pain, burning sensations, or numbness that travels down one or both legs.

By relieving pressure on the compressed nerve root, decompression reduces inflammation and irritation along the nerve pathway. As nerve function is restored, patients often experience significant relief in both pain intensity and frequency.

Patient Outcome: In most cases, decompression helps resolve sciatica symptoms caused by disc pressure within a few weeks of consistent care.

Spinal Stenosis (Mild to Moderate)

Spinal stenosis involves a narrowing of the spinal canal that puts pressure on the spinal cord or nerves.

While severe stenosis may require surgical intervention, mild to moderate cases can often be managed effectively through non-surgical decompression.

Decompression gently opens the space between vertebrae, improving circulation and reducing nerve irritation. This can decrease numbness, tingling, and weakness in the arms or legs while restoring comfort during walking or standing.

Clinical Note: Many patients with lumbar stenosis notice improvements in walking distance and standing tolerance after decompression therapy.

Chronic Lower Back or Neck Pain

Chronic back or neck pain often results from long-term compression, poor posture, or minor disc injuries that never fully heal.

Decompression reduces internal disc pressure, relaxes supporting muscles, and improves joint motion, which collectively help calm chronic inflammation and pain sensitivity.

Patients who sit or stand for long hours, lift heavy objects, or have poor posture often benefit most from this type of care. 

Over time, decompression therapy can improve spinal alignment and prevent recurring episodes of pain.

Failed Back Surgery Syndrome (FBSS)

Failed back surgery syndrome refers to ongoing pain after spinal surgery that did not fully resolve the underlying problem.

 In many cases, scar tissue or incomplete disc healing continues to irritate the surrounding nerves.

Spinal decompression offers a non-invasive way to relieve pressure without the risks or downtime of additional surgery. 

By improving nutrient flow and reducing mechanical stress, decompression helps restore motion and comfort for patients still recovering from surgical interventions.

“Patients who have tried multiple treatments without lasting results often find decompression to be a turning point. It gives the spine a chance to heal naturally by addressing the pressure that other methods may have missed.” – Dr. Jason Crist

Summary of Ideal Candidates

Spinal decompression is best suited for patients who:

• Have chronic back or neck pain lasting longer than six weeks
  
• Have MRI or imaging confirmation of disc herniation or degeneration
  
• Experience radiating pain, tingling, or numbness in the limbs
  
• Prefer to avoid surgery or medications
  
• Are ready to commit to a consistent, evidence-based treatment plan

Traditional Traction Therapy: When and Why It Is Used

Traction therapy has been part of spinal care for decades. It stretches the spine to reduce pressure on discs and joints. However, traction uses static or manual force and does not adjust automatically to the body’s response.

Types of Traction Therapy

Mechanical Traction

• Relies on weights or pulley systems
  
• Delivers a constant force with limited feedback
  
• May cause muscles to tighten, reducing the benefit
  

Manual Traction

• Therapist-guided pulling and stretching
  
• Allows in-moment adjustments
  
• Effectiveness depends heavily on practitioner skill
  

Cervical vs Lumbar Traction

• Applied differently depending on region
  
• Helps temporarily relieve stiffness but lacks disc-specific targeting
  

Where Traction Therapy Excels

• Mild muscle spasm relief
  
• Temporary joint decompression
  
• Post-exercise recovery
  
• Budget-friendly pain management
  

Note: While traction can provide short-term relief, it does not create the negative pressure required for disc rehydration or long-term correction.

Non-Surgical Spinal Decompression vs Mechanical Traction: The Science

Comparative Clinical Evidence

Shealy and Borgmeyer — Decompression vs Traction Outcomes

A landmark comparative study by Shealy and Borgmeyer evaluated decompression (DRS system) versus standard mechanical traction for lumbosacral pain.
(ResearchGate, Decompression, Reduction, and Stabilization of the Lumbar Spine)

• Among patients with ruptured discs, 86% achieved “good-to-excellent” results with decompression compared to 55% with traction.
  
• Fluoroscopic imaging confirmed up to 7 mm of vertebral distraction at L5 during decompression.
  
• The authors noted that the findings were preliminary but demonstrated significant potential for non-surgical pain relief.
  

PMC Review (PMC 5140813) — Promise and Limitations

A broader review of decompression therapy highlights its potential to improve function and relieve discogenic pain. 

The review also notes that many studies have small sample sizes and varying methodologies, so additional high-quality research is still needed.
(PMC 5140813)

Together, these studies suggest that spinal decompression provides stronger long-term benefits than traditional traction while reinforcing the importance of ongoing research.

Biomechanical Differences

Parameter	Spinal Decompression	Traction Therapy
Disc Pressure	Creates negative pressure (–150 to –200 mmHg)	Reduces positive pressure (25–50 mmHg)
Muscle Response	Prevents guarding through controlled cycles	Can trigger muscle tightening
Targeting	Level-specific precision	Broad spinal stretch
Technology	Sensor-guided computer modulation	Manual or mechanical pull
Result Duration	Months to years	Weeks

Educational Note: Negative intradiscal pressure is what makes decompression unique. It allows discs to rehydrate and heal, which leads to longer-lasting relief.

Spinal Decompression vs Traction: Cost and Value Analysis

When comparing costs, decompression offers a higher long-term return on investment despite a slightly higher per-session fee.

Detailed Cost Breakdown

Cost Factor	Spinal Decompression	Traction Therapy
Initial Evaluation	$100–$200	$75–$150
Per Session	$100–$200	$50–$100

Comprehensive FAQ: Spinal Decompression vs Traction

Is spinal decompression better than traction?

Most research and clinical experiences suggest decompression provides superior results for disc-related pain by creating negative pressure that promotes healing. 

Traction offers short-term relief but lacks precision.

What is the difference between mechanical traction and spinal decompression?

Mechanical traction applies a continuous, static pull. Spinal decompression alternates pull and relaxation cycles using computer control to reduce muscle resistance and improve disc rehydration.

How much more expensive is decompression than traction?

Decompression sessions cost roughly twice as much, but patients usually need fewer visits, making the overall investment comparable or even lower long-term.

Can an inversion table replace professional decompression?

No. Inversion tables use gravity to stretch the spine, but cannot generate the targeted negative pressure required for disc healing.

Which works best for herniated discs?

Spinal decompression is typically more effective. The Shealy and Borgmeyer study showed 86% improvement with decompression compared to 55% with traction.

Does insurance cover decompression or traction?

Both may be covered if medically necessary. Decompression is increasingly recognized by insurers when prescribed by chiropractors.

How can I tell which treatment I need?

A professional evaluation is necessary. Dr. Crist will assess your condition, imaging, and symptoms to recommend the best course of care.

Can decompression and traction be combined?
