Spinal Decompression for Herniated Disc Pain: What to Know

Spinal decompression for herniated disc pain is a gentle, non-surgical treatment that may ease leg pain for some people as part of a wider care plan. The trials that found a benefit looked only at short-term results. However, it is not a sure thing. Larger reviews show mixed results, and the table is not right for everyone.

If you are hurting right now, that can feel like a lot to sort through. So below, we explain how the table works and what the research really says. We also cover who should skip it, what a session feels like, and how Dr. Jenna Patel, D.C. decides if it fits you.

What a herniated disc is, and why your leg may hurt

Between the bones of your spine sit small, rubbery cushions called discs. Each one has a tough outer ring and a softer center. In a herniated disc, some of that soft center pushes out through a weak spot or tear in the ring. As a result, it can press on or irritate a nearby nerve root.

In the low back, that nerve irritation often causes sciatica. You may feel pain, numbness or tingling that runs from your buttock down one leg. Some people also feel weakness in the leg or foot. The good news is that most herniated disc and sciatica flare-ups improve with time and conservative care. Sciatica often eases over several weeks, although it can come back.

How spinal decompression for a herniated disc works

Non-surgical decompression is a type of motorized, computer-controlled traction. First, you lie on the table, fully clothed. Then one strap goes around your pelvis and another goes around your trunk. Next, the table gently pulls and relaxes in cycles.

The goal is to ease pressure on the discs and on the nerve roots next to them. That said, how decompression works inside the body is still a theory. Because nothing goes inside your body, there are no needles or incisions involved.

What research says about spinal decompression for herniated disc pain

Here is the honest picture. A 2022 trial studied adults with a herniated disc in the low back. One group had 10 decompression sessions over 8 weeks, and the other had the same sessions with no pulling force. At 2 months, that group reported less leg pain than the comparison group. Even so, that was a short-term result.

Another 2022 trial added decompression to routine rehab. In that study, the decompression group did better on pain and disability than the group with rehab alone. So for some people with disc-related leg pain, decompression as part of a plan may help in the short term.

On the other hand, larger reviews show mixed results. Some guidelines do not recommend traction for general low back pain. In addition, a trial that compared a decompression system with a sham version found that both groups improved, with no difference between them. Plain motorized traction also did about as well as decompression in one study. Our post on how decompression compares with traction explains the difference.

You may also see ads that call a table “FDA cleared.” The FDA regulates these tables as Class II powered traction devices. They typically reach the market through 510(k) clearance, which means the FDA found them similar to an earlier device. However, clearance is not FDA approval, and it does not prove a table works better than other care.

Who may be a good fit

Decompression is one option, not the only one. Dr. Patel may suggest it when your exam points to a disc problem behind your leg pain. It may also make sense if you want to try non-surgical care and are willing to do the exercises that go with it. In those cases, spinal decompression for a herniated disc may ease leg pain for some people as part of a plan. The word may matters here, because no one can promise a result.

If your leg pain comes from a narrowed spinal canal instead, the evidence looks different. For stenosis, there is not enough evidence for traction on its own. Our post on decompression for spinal stenosis covers that topic.

Who should not have spinal decompression for a herniated disc

Decompression is not right for everyone. According to WebMD’s guide to spinal decompression therapy, people with these conditions are not candidates:

  • Pregnancy
  • A fracture in the spine
  • Tumors
  • An abdominal aortic aneurysm
  • Advanced osteoporosis, or severe bone loss
  • Metal implants or hardware in the spine

Dr. Patel also screens for recent spinal surgery, infection and instability. If decompression is not a safe fit for you, she will tell you why. Then she will talk through other options, including seeing a medical doctor when that makes more sense.

What a session feels like, and possible side effects

The pull is meant to feel like a gentle stretch, not a sharp tug. You lie still and rest while the table works through its cycles. If anything feels wrong, tell us right away, and we can change the settings or stop.

Of course, plans vary from person to person. The WebMD guide gives a commonly described schedule: sessions of 30 to 45 minutes, often 20 to 28 treatments over 5 to 7 weeks. Research trials often used fewer sessions. Your plan may look different, because Dr. Patel sets it after an exam and rechecks your progress. If you are not improving, we change course.

As for side effects, some trials reported short-term soreness or a temporary increase in pain. In general, serious problems are uncommon. Even so, a Cochrane review noted that many trials did not report side effects well. That is one more reason we check in with you at each visit.

Is spinal decompression for a herniated disc the same as surgery?

No. Surgical decompression is an operation that removes bone or disc tissue to take pressure off a nerve. Non-surgical decompression, by contrast, uses a motorized table and straps while you stay clothed. You can read more in our post on decompression versus surgery.

We cannot promise that decompression will keep you from needing surgery, and no one honestly can. Remember, most herniated disc flare-ups improve with time and conservative care. Still, if you have worsening weakness or the warning signs below, please see a medical doctor soon.

When to see a doctor or go to the ER

Some symptoms need medical care first, not a chiropractor. Go to the ER right away if you have:

  • Loss of bladder or bowel control
  • Numbness in the groin, buttocks or inner thighs

Those can be signs of cauda equina syndrome, which is an emergency. Also see a medical doctor promptly if you notice any of these:

  • Leg weakness, or a foot that drags or slaps when you walk (foot drop)
  • Fever along with back pain
  • A history of cancer, or weight loss you cannot explain
  • Back pain that started after a fall
  • Night pain that wakes you up

How we approach it at HealthSource of Roseland

At our Roseland office on Eisenhower Parkway, Dr. Patel evaluates you before she suggests any treatment. To begin, your first visit includes a health history and a consultation. Next, she does a physical exam of your posture, mobility and pain. We take X-rays only if clinically needed.

After that, Dr. Patel explains her findings and a personalized care plan before any care starts. If decompression fits, she may combine it with adjustments, soft tissue work and exercise rehab. You can learn more on our spinal decompression service page. And if your exam points to a different cause, our back pain relief page explains other options.

We also know many people worry about being pushed into long plans. So we keep things clear. You can ask questions and take time to think before you decide. Along the way, Dr. Patel rechecks your progress, and if you are not improving, we change course.

We accept most major insurance plans, but coverage for decompression varies. Medicare covers chiropractic manipulation for subluxation and not other services such as decompression, so call your plan and us to check.

A calm next step

You do not have to decide about decompression today. A good first step is a clear answer about what is causing your pain. Ask about our new-patient visit: consultation, exam and X-rays if clinically needed. The offer is for new patients only. It does not apply to Medicare, Medicaid, other federal healthcare program patients or ACN members.

When you are ready, you can book online or call (973) 200-2424. You can also talk with Dr. Patel in English, Hindi or Gujarati. This article is for education only and is not a diagnosis.
