If you have been living with a herniated disc, sciatica, or chronic back pain, and medication or standard physical therapy has not given you lasting relief, spinal decompression therapy may be the treatment you have not tried yet.
Spinal decompression is a non-surgical, FDA-cleared treatment that gently stretches the spine to relieve pressure on compressed discs and pinched nerves. It is one of the most effective interventions available for disc-related pain, and it is available right here in St. Louis at Citrin Chiropractic Center.
This guide explains exactly what spinal decompression therapy is, how it works at a mechanical and physiological level, who it helps, and what to expect during treatment.

What Is Spinal Decompression Therapy?
Spinal decompression therapy is a motorized traction treatment performed on a specialized table. The table creates a controlled, intermittent stretching force along the spine, gently pulling the vertebrae apart to create negative pressure inside the spinal discs.
The key word here is negative pressure. In a compressed or herniated disc, the internal disc pressure is positive, meaning the damaged disc material is being pushed outward, toward the nerve roots. This is what causes the sharp, radiating pain of sciatica or the numbness and tingling down the arm from a cervical disc herniation.
Decompression reverses that pressure gradient. By creating negative intradiscal pressure, it does two things: it draws the bulging disc material back toward the center of the disc, and it promotes the flow of oxygen, water, and nutrients into the disc, the raw materials the disc needs to heal.
Key distinction: Spinal decompression is not the same as standard traction. Traditional traction applies a constant pulling force, which can trigger muscle guarding and produces limited disc-level effects. Decompression uses a computerized, cyclic distraction pattern that bypasses the muscle guarding reflex and reaches the disc itself.
How Does Spinal Decompression Work? The Science
Understanding why spinal decompression works requires a basic understanding of disc anatomy. Spinal discs act as shock absorbers between each vertebra. They have a tough outer shell, the annulus fibrosus, and a soft, gel-like inner core, the nucleus pulposus.
When a disc is herniated or bulging, the nucleus pulposus has pushed through a tear in the annulus and is pressing on a nerve root. This is the source of sciatica, radiculopathy, and radiating pain. The disc itself cannot repair this tear without adequate blood supply, and adult spinal discs have very limited blood flow. They depend on a process called imbibition: the pumping of nutrients in and waste products out through changes in pressure.
Spinal decompression drives this imbibition process by repeatedly creating and releasing negative pressure in the disc. Over a course of treatment, typically 15 to 25 sessions, this promotes disc rehydration, encourages retraction of the herniated material, and creates the biological conditions for the annulus to heal.
Clinical note: Studies on non-surgical spinal decompression show 71-89% patient satisfaction rates for disc herniation and sciatica. It is not a cure for all spinal conditions, but for the right candidate, it produces outcomes that have historically required surgery.
What Happens During a Spinal Decompression Session?
A standard decompression session at Citrin Chiropractic takes approximately 30 to 45 minutes. Here is exactly what happens:
| # | Step | What Happens |
| 1 | Initial consultation | Our doctor reviews your imaging, medical history, and symptoms to confirm you are a candidate for decompression. |
| 2 | Harness fitting | A pelvic harness is fitted around your waist. A second harness secures the thoracic region. You remain fully clothed. |
| 3 | Positioning on table | You lie face-up (supine) or face-down (prone) depending on which disc levels are being targeted. |
| 4 | Distraction phase | The table applies a slow, precise pulling force, typically 50 to 100 lbs, over 60 seconds, then releases. |
| 5 | Cyclic decompression | The pull-and-release cycle continues for the full session duration. Most patients feel gentle traction and find it relaxing. |
| 6 | Supportive therapies | Sessions are often followed by ice, heat, or electrical stimulation to support healing in the decompressed disc tissue. |
Most patients describe the sensation as a gentle pulling or stretching, not painful, and often relaxing. Some patients fall asleep during sessions. If you experience discomfort at any point, the session is immediately stopped. Patient comfort and safety guide the entire process.
How many sessions are needed? A typical course of spinal decompression therapy involves 15 to 25 sessions over 4 to 8 weeks, depending on the severity of your condition. Our doctors re-evaluate your progress regularly and adjust the treatment plan accordingly.
Who Is a Good Candidate for Spinal Decompression?
Spinal decompression is highly effective for a specific group of conditions, all involving disc-related spinal compression. It is not appropriate for all types of back pain. Here is a clear breakdown of who is a candidate for spinal decompression:
| Good Candidates | Not Recommended For |
| ✓ Herniated or bulging disc | ✗ Severe osteoporosis |
| ✓ Degenerative disc disease (DDD) | ✗ Spinal fractures or instability |
| ✓ Sciatica from disc compression | ✗ Spinal tumors or cancer |
| ✓ Facet syndrome | ✗ Advanced spinal stenosis (severe) |
| ✓ Spinal stenosis (mild to moderate) | ✗ Pregnancy |
| ✓ Failed back surgery syndrome | ✗ Metal implants in the spine |
| ✓ Chronic lower back pain | ✗ Active infection in the spine |
| ✓ Neck pain from disc involvement | ✗ Aortic aneurysm |
| ✓ Radiating arm or leg pain (radiculopathy) | |
| ✓ Disc injuries from car accidents |
If you are unsure whether you are a candidate, a consultation with our doctors is the right first step. We review your imaging, MRI, X-rays, or CT scans, and your symptom history to determine whether decompression is appropriate for your specific condition.
Conditions Spinal Decompression Treats
Herniated Disc
The most common and most effectively treated condition with decompression. A herniated disc Treatment causes radiating pain, numbness, or weakness in the arm or leg depending on which level of the spine is affected. Decompression directly addresses the disc pressure causing the nerve compression.
Sciatica
Sciatica is not a diagnosis, it is a symptom. It refers to pain radiating down the leg from compression of the sciatic nerve, usually caused by a disc herniation or bone spur at L4-L5 or L5-S1. Spinal decompression for sciatica directly reduces the disc pressure causing that nerve compression, often producing significant relief when other treatments have failed.
Degenerative Disc Disease
As discs age and lose hydration, they collapse and can compress nerve roots. Spinal decompression therapy promotes disc rehydration and creates the mechanical conditions for slowing degeneration, it cannot reverse disc aging, but it can significantly reduce the pain it causes.
Disc Injuries From Car Accidents
Collision forces frequently cause disc herniations and bulges that are not immediately apparent. These are a significant source of delayed back pain after a car accident. Decompression is one of the most effective treatments for post-accident disc injuries and is billable to auto insurance in most cases.

Most local practices refer patients out for decompression therapy. At Citrin, it is part of your integrated care plan from day one — no referrals, no delays, no separate billing relationships to manage. |
Spinal Decompression vs. Surgery: Is It Worth Trying First?
For patients who have been told they need surgery for a herniated disc or sciatica, non-surgical spinal decompression is worth attempting before going under the knife. Here is why:
- Surgery carries real risks: infection, failed back surgery syndrome, adjacent segment disease, and lengthy recovery times measured in months
- Spinal fusion permanently alters spinal mechanics and often leads to accelerated degeneration at adjacent levels
- Decompression is non-invasive, has no recovery downtime, and produces no permanent structural changes
- Many patients who have tried and failed with physical therapy, epidural injections, or pain management respond very well to decompression
- If decompression does not produce adequate relief, surgery is still an option, it is not an either/or decision
Our doctors are transparent about candidacy. If your imaging and symptoms suggest that surgery is the more appropriate first-line intervention, we will tell you that directly. But for most disc conditions, spinal decompression deserves a genuine trial before surgery is pursued.

Frequently Asked Questions
Is spinal decompression therapy painful?
No, spinal decompression therapy is not painful. Most patients describe the sensation as a gentle, rhythmic stretching that is comfortable and often relaxing. If any discomfort occurs during a session, the treatment is immediately stopped. Sessions are fully controlled and patient comfort is the top priority.
Is spinal decompression safe?
Yes. Spinal decompression is FDA-cleared and has an excellent safety profile when performed on appropriate candidates. It is not recommended for patients with fractures, severe osteoporosis, spinal implants, or certain other conditions, which is why a thorough evaluation is performed before treatment begins.
How many spinal decompression sessions do I need?
Most patients require between 15 and 25 sessions over 4 to 8 weeks. The exact number depends on the severity of your condition, how long it has been present, and how your body responds to treatment. Our doctors re-evaluate regularly and will not recommend sessions beyond what your condition requires.
Does insurance cover spinal decompression therapy?
Coverage for spinal decompression therapy varies by insurance plan. Some plans cover it as a chiropractic benefit; others classify it separately. For patients whose disc injuries resulted from a car accident, auto insurance (MedPay or PIP) typically covers decompression as part of injury treatment. We verify your coverage before your first session and explain your options clearly.
How is spinal decompression different from regular traction?
Traditional traction applies a constant pulling force, which often triggers involuntary muscle guarding that limits how much force actually reaches the disc. Spinal decompression uses a computerized, cyclic distraction-relaxation pattern specifically designed to bypass muscle guarding and create targeted negative pressure within the disc itself. This distinction is clinically significant.
Can spinal decompression help after a car accident?
Yes, disc injuries are among the most common delayed injuries from car accidents. Spinal decompression for herniated discs caused by collision forces is one of the most effective non-surgical treatments available. It is also billable to auto insurance in most cases. If you have back or radiating leg pain that developed after a car accident in St. Louis, call us for an evaluation.
