If you are asking how long spinal decompression lasts, the honest answer comes in two parts. The visits are fairly short, and the courses commonly described run for several weeks. The relief is harder to pin down. Some trials found that people with disc-related leg pain had less pain in the short term when decompression was part of a care plan, but nobody can honestly promise that you will get relief or how long it will hold. Below, we explain what the research shows, why results differ, and what we do to support your progress. We also share how Dr. Jenna Patel, D.C. decides if this care fits you.
How long does a spinal decompression session last?
Non-surgical spinal decompression uses a computer-controlled table to apply gentle, motorized traction. You lie on the table fully clothed, with harnesses around your pelvis and trunk. The table then pulls and relaxes in cycles, easing your lower back into a light stretch and letting it rest again.
According to WebMD, sessions commonly last 30 to 45 minutes. During that time, your main job is to lie still and relax. If you feel nervous about the pull itself, read our post on what a session feels like before your first visit.
One quick note: surgical decompression is a different thing. In that operation, a surgeon removes bone or disc tissue to make room for a nerve. Everything in this post is about the non-surgical table.
How long a full course of care usually takes
Plans vary, so treat any number you read as a rough guide. WebMD describes courses that often run 20 to 28 treatments over 5 to 7 weeks. Research studies have used 10 to 20 sessions. Your own plan may look different from both.
Here is how we handle it. Dr. Patel sets a plan after an exam and rechecks your progress. If you are not improving, we change course. That way, the length of your care follows how your body responds. Our post on how many sessions people need and how often goes into more detail on timing.
How long does relief from spinal decompression last?
This is the part most people really want to know, and the answer is that it varies. The encouraging research findings are short-term ones. For example, in a 2022 randomized trial, people with a recent herniated disc in the low back had 10 decompression sessions over 8 weeks. At 2 months, they had less leg pain than a comparison group whose table used no pulling force. That is a real finding, but it does not tell us how people felt a year or more later.
Other sources fit the same picture. Cleveland Clinic lists traction among self-care options for degenerative disc disease that may ease pain for a short time. It does not present traction as a long-term fix. Larger reviews of traction show mixed results, and some guidelines do not recommend it for general low back pain. Also, in another trial that compared a decompression system with a sham treatment, both groups improved, with no difference between them.
Put together, how long spinal decompression relief lasts is different for each person, and no one can promise you a set number of months. We explain this so you can decide for yourself, not to talk you out of care. For a deeper look at the studies, read what the research shows about whether decompression works.
Why spinal decompression results differ from person to person
A few things help explain why results are so hard to predict. First, the goal of decompression is to ease pressure on discs and nerve roots, and how it works is still a theory. The trials with encouraging results looked mostly at leg pain tied to a bulging or herniated disc, not at every backache.
Second, time plays a big role. Most sciatica and herniated disc episodes improve with time and conservative care. That makes it hard to know how much of anyone’s relief came from the table itself. Sciatica can also come back, even after weeks of feeling better.
Third, the rest of your plan matters. Some of the encouraging trials added decompression to an exercise and rehab program. It was one piece of care, not the whole plan, and that is how Dr. Patel uses it too.
Who should not have spinal decompression
This care is not for everyone. WebMD lists these reasons to skip it:
- Pregnancy
- A fracture or a tumor
- An abdominal aortic aneurysm
- Advanced osteoporosis
- Metal implants or hardware in the spine
Dr. Patel also screens for recent spinal surgery, infection and instability in the spine. If any of these apply, decompression is not a fit, and we talk with you about other options.
Side effects to know about
The table pulls gently, but your body can still react. Some trials reported short-lived soreness or a temporary rise in pain. Serious problems are uncommon, although Cochrane noted that many trials did not report side effects well. Tell us right away if your leg pain gets worse during or after a session, so Dr. Patel can adjust or stop.
Questions to ask before you start
A good plan should make sense to you before the first session. Bring these questions to your visit, and expect clear answers:
- How will we know if the care is helping me?
- When will you recheck my progress?
- What happens if I am not improving?
- Which exercises should I do at home or at work?
- Does my insurance plan cover any of this?
Asking them is a normal part of your visit, and we are glad to answer. You should never feel rushed into a long plan you do not understand.
When to see a doctor or go to the ER
Some symptoms need a medical doctor first, not a chiropractor. Go to the ER right away if you notice either of these:
- Loss of bladder or bowel control
- Numbness in the groin, buttocks or inner thighs
These can be signs of cauda equina syndrome, a nerve emergency. Also see a medical doctor soon if you have:
- New leg weakness
- Fever along with back pain
- A history of cancer, or weight loss you cannot explain
- Pain that started after a fall
- Back pain that wakes you at night

How we approach it at HealthSource of Roseland
At our Roseland office, Dr. Patel evaluates you before any care starts. Your first visit includes a health history questionnaire, a consultation, and a physical exam of your posture, mobility and pain. We take X-rays only if clinically needed. Then she explains a report of findings and a personalized care plan, so you know what to expect.
If decompression fits your exam, it becomes one part of your plan. Dr. Patel may pair it with hands-on adjustments, soft tissue work, and Progressive Rehab® and functional exercise. She looks for the source of the problem, not only the symptoms, and she offers nutrition and lifestyle guidance as well. You can learn more on our decompression service page. As care goes on, she rechecks your progress, and if you are not improving, we change course.
Cost matters too. Medicare covers chiropractic manipulation for subluxation and not other services such as decompression, so call your plan and us to check. We accept most major insurance plans and offer financing through Cherry and CareCredit.
If disc-related leg pain is wearing you down, you do not have to guess what might help on your own. Book a visit online or call (973) 200-2424, and we can talk through your options. Ask about our new-patient visit: consultation, exam and X-rays if clinically needed. The offer is for new patients only and does not apply to Medicare, Medicaid, other federal healthcare program patients or ACN members.
