Spinal decompression therapy is a non-surgical treatment that gently stretches the spine to relieve pressure on compressed discs and pinched nerves. If you have been diagnosed with a herniated or bulging disc, sciatica, or degenerative disc disease and want to avoid surgery, decompression therapy may be exactly what you need. Here is how it works, what a session feels like, and who benefits most from this treatment.
How Spinal Decompression Works
Non-surgical spinal decompression uses a motorized table to apply a controlled, intermittent pulling force to your spine. You lie on the table, either face up or face down depending on the area being treated, and a harness is fitted around your hips. The table's computer system then cycles through periods of gentle stretching and relaxation.
This cycling creates negative pressure inside the disc, a phenomenon called negative intradiscal pressure. When the pressure inside the disc drops below the pressure outside it, several things happen:
- Disc retraction: Herniated or bulging disc material gets drawn back toward the center of the disc, away from the nerve it was compressing.
- Nutrient flow: The negative pressure pulls water, oxygen, and nutrients into the disc, which promotes healing. Spinal discs have limited blood supply, so this pumping action is one of the only ways to deliver healing nutrients directly to the damaged tissue.
- Nerve decompression: As the disc retracts and the space between vertebrae opens up, pressure on the spinal nerve decreases. This is what relieves the radiating pain, numbness, and tingling associated with conditions like sciatica.
A 2007 clinical study published in BMC Musculoskeletal Disorders found that patients with chronic low back pain who received non-surgical spinal decompression reported significant reductions in pain, with 71% of patients showing improvement (BMC Musculoskeletal Disorders, 2007). More recent reviews continue to support its effectiveness as a conservative treatment option for disc-related pain.
What Conditions Does It Treat?
Spinal decompression therapy is most effective for conditions that involve disc compression or nerve pressure in the spine:
Herniated Discs
When the soft inner material of a disc pushes through a tear in the outer wall, it can press on nearby nerves. Decompression creates the negative pressure needed to draw that material back inside the disc.
Bulging Discs
A bulging disc extends beyond its normal boundary but has not ruptured. Decompression reduces the outward pressure that causes the bulge and helps the disc return to its proper shape.
Sciatica
Sciatica is pain that radiates from the lower back down through the buttock and leg, caused by compression of the sciatic nerve. When a disc in the lumbar spine is the source of that compression, decompression therapy addresses it directly. Learn more about chiropractic care for sciatica.
Degenerative Disc Disease
As discs lose hydration and height over time, the vertebrae move closer together, putting pressure on nerves and facet joints. Decompression opens that space back up and delivers nutrients that slow the degenerative process. Read more about chiropractic approaches to degenerative disc disease.
Spinal Stenosis
Narrowing of the spinal canal can compress the spinal cord or nerve roots. Decompression therapy helps by opening the spaces where nerves exit the spine, reducing compression symptoms. For a deeper look at this condition, see our guide to chiropractic care for spinal stenosis.
What a Session Feels Like
Each decompression session lasts about 30 to 45 minutes. Here is what to expect:
- You change into comfortable clothing and lie on the decompression table.
- Your chiropractor fits a harness around your pelvis and secures you to the table.
- The computer-controlled table begins its cycle, alternating between gentle pulling and relaxation phases. Each pull lasts about 30 to 60 seconds, followed by a brief rest period.
- You feel a stretching sensation in your lower back or neck, but it should not be painful. Most patients describe it as a gentle pull that actually feels good.
- Many patients relax so deeply during treatment that they fall asleep on the table.
"The most common thing I hear after a first decompression session is 'that's it?'" says Dr. Austin Elkin. "People expect it to be uncomfortable because they are in so much pain. But the treatment itself is one of the most comfortable things we do. The table does the work while you rest."
How Many Sessions Do You Need?
A typical decompression protocol involves 15 to 30 sessions spread over 4 to 8 weeks. Most patients are scheduled 3 to 5 times per week. The frequency is important because the changes to disc pressure are cumulative. Each session builds on the last.
Here is a general timeline:
- Sessions 1 to 5: You may notice temporary relief after sessions, but symptoms can return between visits. This is normal. The disc is beginning to respond but has not yet stabilized.
- Sessions 6 to 15: Relief lasts longer between sessions. Many patients report significant improvement in pain levels, reduced radiating symptoms, and better mobility during this phase.
- Sessions 15 to 30: Structural changes become more stable. Pain levels continue to drop. Your chiropractor may begin spacing sessions further apart as the disc holds its improved position.
Decompression is typically combined with chiropractic adjustments, therapeutic exercises, and sometimes electrical stimulation or cold therapy to maximize results. Learn more about our spinal decompression therapy services at City of Palms Chiropractic.
Who Is a Good Candidate?
You may be a good candidate for spinal decompression if you have:
- A diagnosed herniated, bulging, or degenerative disc
- Sciatica or radiating leg pain that has not responded to other conservative treatments
- Chronic low back or neck pain lasting more than 4 weeks
- Failed other treatments like medication, physical therapy, or injections
- Been told you need spinal surgery but want to try a non-surgical option first
Who Should Not Get Decompression Therapy?
Spinal decompression is not appropriate for everyone. Contraindications include:
- Pregnancy: The harness and pulling forces are not safe during pregnancy.
- Spinal fractures: Active fractures need to heal before decompression can be used.
- Spinal hardware: If you have metal implants, rods, or screws from a previous spinal surgery, decompression may not be safe.
- Severe osteoporosis: Bones weakened by osteoporosis may not tolerate the pulling force.
- Spinal tumors or infections: These require medical treatment first.
- Abdominal aortic aneurysm: The harness position creates risk for this condition.
Your chiropractor will perform a thorough examination, review your medical history, and may take X-rays or review existing MRI images before recommending decompression therapy. According to a review published in the Journal of the Canadian Chiropractic Association, proper patient selection is the most important factor in achieving successful outcomes with spinal decompression (JCCA, 2020).
Frequently Asked Questions
Does spinal decompression hurt?
No. Most patients find spinal decompression comfortable, and many fall asleep during sessions. You may feel a gentle stretching sensation in your spine, but it should never be painful. The table's computer system adjusts the pull force gradually, and your chiropractor can modify settings at any time based on your comfort level.
How many spinal decompression sessions do I need?
A typical treatment plan includes 15 to 30 sessions over 4 to 8 weeks. Most patients are scheduled for 3 to 5 sessions per week. The exact number depends on the severity of your condition, how long you have had it, and how your body responds. Your chiropractor will reassess your progress and adjust the plan as needed.
Is spinal decompression covered by insurance?
Coverage varies by insurance plan. Some plans cover spinal decompression therapy when it is medically necessary and prescribed by a doctor. Others classify it as a non-covered service. City of Palms Chiropractic can verify your benefits before treatment begins and offers payment options for patients paying out of pocket.
What is the difference between surgical and non-surgical spinal decompression?
Non-surgical spinal decompression uses a motorized table to gently stretch the spine and create negative pressure within the disc, encouraging retraction of herniated material and nutrient flow. Surgical decompression involves procedures like laminectomy or discectomy to physically remove tissue pressing on nerves. Non-surgical decompression is a conservative first-line option with no incision, no anesthesia, and no recovery time.
