What is spinal decompression?

Spinal decompression is motorized traction that gently and gradually lengthens the spine in controlled cycles of pulling and relaxing. It is designed to reduce pressure on spinal discs and the nerves around them, and to support the movement of water, oxygen and nutrients into the disc. It is non-surgical and drug-free, and you stay fully clothed.

Your spinal discs sit between the vertebrae like small, firm cushions. Each has a tough outer ring and a softer gel-like center. When a disc bulges, herniates or wears down over time, it can press on nearby nerves and cause pain in the back or neck, or pain, tingling and numbness that travel into the arms or legs.

The DRX9000 is a computer-controlled spinal decompression table. Unlike a simple stretch, it continuously monitors how your body responds and adjusts the pull, which is intended to help the surrounding muscles stay relaxed rather than tense up and guard against the stretch.

How does spinal decompression work?

Decompression slowly separates the vertebrae a small amount, then eases off, in repeating cycles. This is designed to create negative pressure inside the disc — a gentle vacuum effect — which may help draw bulging disc material inward and encourage fluid and nutrients back into the disc. Many patients notice the treated area feels less compressed.

Researchers describe this as "negative intradiscal pressure." In plain terms: when you sit or stand, gravity and body weight squeeze your discs. Decompression is designed to briefly reverse that squeeze. Discs have a limited blood supply and rely on this kind of fluid exchange, so reducing pressure may support the body's own healing processes. Responses differ from person to person, and results vary.

  • Lumbar decompression — for the low back, often used for low back pain and sciatica.
  • Cervical decompression — for the neck, often used for neck pain and pain or tingling in the arms.

Why did we choose the DRX9000?

We chose the DRX9000 for its precision, comfort and safety. We like to call it the Ferrari of spinal decompression. It's an FDA-cleared, computer-controlled system that adjusts to your body in real time and can be set to target the specific disc level your exam identifies, in the low back or the neck.

The DRX9000 is made by Excite Medical in Tampa, Florida, and according to the manufacturer it's used in more than 1,200 hospitals, clinics and health centers in over 50 countries.

  • Targets the problem disc

    A lumbar level selector and adjustable treatment angle let Dr. Craig focus the pull on the disc level found in your exam, instead of stretching the whole spine the same way.

  • Adjusts to your body in real time

    A servo motor and closed-loop feedback system monitor how your body responds and fine-tune each gradual pull-and-release cycle, which is designed to help your muscles stay relaxed instead of guarding.

  • Low back and neck

    The same system offers both lumbar and cervical decompression, so Dr. Craig can address disc problems in either area.

  • Built for comfort

    You stay fully clothed with a knee pillow, head pillow, upper-body support and a floating lower mattress, and many sessions include music or a video on the built-in screen.

  • Safety you control

    You hold a safety switch during every session and can stop treatment at any time.

  • FDA-cleared

    The DRX9000 has FDA 510(k) clearance for treating herniated discs, bulging discs, degenerative disc disease and posterior facet syndrome.

The equipment matters, but so does the person using it. Dr. Jerome Craig evaluates every patient first and recommends decompression only when the exam suggests it's a good fit.

Who may benefit from spinal decompression?

Spinal decompression may help adults with back or neck pain caused by disc problems or nerve pressure, especially when pain has lasted for weeks or months and other conservative care hasn't been enough. Common reasons people ask about it include herniated or bulging discs, sciatica and degenerative disc disease. Candidacy is always decided at an exam.

Conditions that may respond to decompression include:

Who is spinal decompression not right for?

Spinal decompression is not appropriate for everyone. You are generally not a candidate if you are pregnant or have had a lumbar fusion, or if you have surgical hardware in the treatment area, a recent spinal compression fracture, severe osteoporosis, unstable spondylolisthesis, a pars defect, metastatic cancer or cancer in the pelvis or abdomen, a disc-space infection, an abdominal aortic aneurysm, severe peripheral neuropathy, paralysis (hemiplegia or paraplegia) or cognitive impairment. Decompression is for adults 18 and older. Dr. Craig decides at your exam.

Some severe cases of spinal stenosis are also not a good fit. If decompression isn't right for you, Dr. Craig will explain why and talk through other options, which may include chiropractic care or a referral to another provider.

Seek emergency care right away if you have new loss of bladder or bowel control, numbness in the groin or inner thighs, or leg weakness that is getting worse. These can be signs of cauda equina syndrome, which needs urgent medical attention — not decompression.

What is a spinal decompression session like?

A session lasts about 30 minutes. You stay fully clothed, are fitted with a comfortable harness, and lie on the DRX9000 table. The table then gently applies and releases traction in cycles. Most people feel a mild, steady stretch rather than pain, and many find the session relaxing — some even fall asleep.

  1. 1Free consultation: talk with Dr. Craig about your symptoms, history and goals to see whether decompression may suit you.
  2. 2Examination: a chiropractic exam, with imaging such as X-rays or MRI reviewed if needed, to confirm the likely source of your pain and rule out reasons not to treat.
  3. 3Care plan: if you're a candidate, Dr. Craig recommends a plan. Care plans often combine decompression with chiropractic care and simple home exercises.
  4. 4Treatment sessions: you're positioned and harnessed on the table, and the DRX9000 runs its cycles of gentle traction and relaxation for about 30 minutes.
  5. 5Progress check-ins: your response is reviewed along the way, and the plan is adjusted as needed.

For neck pain, a padded cradle supports the head while the DRX9000 applies gentle, controlled cycles of cervical decompression.

How many decompression sessions will I need?

The number of sessions depends on your exam, the condition being treated, how long you've had symptoms and how you respond. The manufacturer's standard DRX9000 protocol is about 20 to 24 sessions over roughly six weeks, starting with more frequent visits and tapering off. Dr. Craig will recommend a plan after your exam and adjust it as you go. We won't promise a fixed number.

How does decompression compare with surgery, injections and traction?

Spinal decompression, injections, surgery and regular traction are different approaches with different goals, costs and risks. Decompression is non-surgical and typically involves little or no downtime, but it isn't right for every condition. The table below summarizes general differences; the right option for you depends on your diagnosis and should be discussed with your providers.

What does the research say about the DRX9000?

Research on DRX9000 decompression is growing, and recent studies report meaningful improvements in pain and function for many patients with disc-related low back pain. Most published studies are retrospective or small case series without a control group, so more randomized trials are still needed. Individual results vary.

Spinal Decompression FAQ

Does spinal decompression hurt?

Most people don't find spinal decompression painful. You'll feel a gentle, gradual stretch as the table pulls and then relaxes. Many patients find sessions relaxing. If anything feels uncomfortable, tell Dr. Craig and the settings can be adjusted. Some people feel mild soreness afterward, similar to after a new stretch or exercise.

How is decompression different from a chiropractic adjustment?

A chiropractic adjustment is a quick, targeted movement applied to a specific joint to improve motion. Spinal decompression is a slow, computer-controlled stretch of the spine over about 30 minutes, designed to reduce pressure on discs and nerves. Many care plans use both together, with Dr. Craig deciding which fits your condition.

What makes the DRX9000 different from other decompression tables?

The DRX9000 is an FDA-cleared, computer-controlled system that adjusts its pull in real time based on how your muscles respond, and its treatment angle can be set to target a specific disc level in the low back or neck. That precision and comfort are why ALVIS chose it for our Portland clinic.

Is the DRX9000 FDA approved?

The DRX9000 is FDA-cleared through the 510(k) process, which is how the FDA reviews devices like this. Approval is a different pathway used for higher-risk devices. Its clearance covers the treatment of herniated discs, bulging discs, degenerative disc disease and posterior facet syndrome.

Is there research on DRX9000 spinal decompression?

Yes. A 2025 review of 267 patient records published in Military Medicine reported average pain dropping from 6.9 to 2.5 out of 10, and a 2025 University of South Florida case series found pain reductions and small increases in disc height on MRI. Both studies lacked control groups, so results vary and more research is needed.

Is spinal decompression covered by insurance?

Spinal decompression is often not covered by insurance, though plans vary. Our team can check your benefits before you start. If it isn't covered, we offer self-pay pricing, payment plans and CareCredit. We'll explain costs clearly at your free consultation so you can make an informed decision.

How many sessions will I need?

It depends on your exam, the condition and how you respond. The manufacturer's standard DRX9000 protocol is about 20 to 24 sessions over roughly six weeks, with more frequent visits at the start. Dr. Craig will recommend a plan after your exam and review your progress regularly instead of promising a fixed number.

Can spinal decompression help sciatica?

It may. When sciatica is caused by a herniated or bulging disc pressing on a nerve root, decompression is designed to reduce that pressure, and many patients with disc-related sciatica explore it. Sciatica has several possible causes, so Dr. Craig first examines you to find the likely source and decide whether decompression fits. Results vary.

Is spinal decompression safe after back surgery?

It depends on the surgery. A spinal fusion, or surgical hardware or implants in the area to be treated, usually means you are not a candidate. Some people who had other procedures may be evaluated. Bring your surgical history to your consultation, and Dr. Craig will tell you honestly whether decompression is appropriate.

Do you offer spinal decompression in Hood River?

No. Spinal decompression is offered only at our Portland clinic at 2916 NE Broadway, Suite B, with Dr. Jerome Craig. At our Hood River clinic, Dr. Andrew Alvis treats disc, back and neck conditions with chiropractic care and can refer you to Portland when your exam suggests decompression may help.

What happens at the free consultation?

At the free consultation you'll talk with Dr. Craig about your symptoms, history, any imaging you've had and your goals. He'll explain how decompression works and whether you may be a candidate, and outline next steps such as an exam. There's no cost and no obligation to start care.
