What to Expect From Spinal Decompression, Session by Session

Spinal decompression at Mecham Chiropractic starts with an exam, then usually runs 20 to 30 sessions of about 20 to 30 minutes each over 8 to 12 weeks, with the plan revisited if treatments 8 to 12 bring no meaningful improvement.

You probably want to know three things: how long this takes, whether it hurts, and when you'll find out if it's doing anything.

Here's the plan in order, from the exam to the last visit, including the point where we stop and ask whether it's worth continuing.

Before the first session: the exam

Decompression doesn't start until Dr. Cody Mecham has examined you.

That exam covers your history, an orthopedic exam and a review of whatever imaging is relevant, so bring your imaging reports if you have them. It's answering two questions. Does your pain behave like a disc problem? And is there anything that makes decompression unsafe for you?

Mecham Chiropractic treats these patterns as pointing toward a disc:

Some findings rule decompression out altogether. A fracture or unstable segment in the spine, hardware left by a fusion, cancer that's active in the spine, osteoporosis past the point where pulling is safe, a pregnancy, or an aortic aneurysm all mean no, and you'll be told so directly rather than sold a plan.

Loss of bladder or bowel control can signal cauda equina syndrome, which is a medical emergency. Get emergency care right away instead of booking a decompression exam.

Your first time on the table

For low back work, a pelvic harness is fitted, and the computer in the DRX9000 table controls the pull.

It isn't a steady pull. The force builds, eases off and builds again, because a constant stretch makes the muscles along the spine brace against it and a cycling one gives them less reason to. That rhythm fills most of a session lasting about 20 to 30 minutes.

Does it hurt? It isn't supposed to.

If you feel real pain during a session, say so right then. At Mecham Chiropractic that's a stop-and-reassess moment, not something to grit your teeth through.

The checkpoint at treatments 8 to 12

If you want one reason to trust a plan, this is the part we'd point to.

Around treatments 8 to 12, Dr. Cody Mecham looks at whether anything meaningful has changed. When it has, the plan continues. When it hasn't, the plan is reconsidered, rather than running out the remaining visits on hope.

Why so early? One reason is the research. When Cochrane reviewers pooled 32 randomized trials in 2013, traction made little or no difference to pain or function, and a treatment with that record should have to show something in your own back, soon. The other reason is arithmetic: in a plan of 20 to 30 sessions, a third to two-thirds of the visits come after the checkpoint, and so does a big share of the cost.

What counts as meaningful? A pain score is only part of it. Tell us about the things that shape your week: sitting through a meeting, sleeping through the night, getting out of the car at a Big Cottonwood trailhead without planning the move first.

Nobody has a formula that predicts who'll pass the checkpoint. We'd rather find out in 8 to 12 visits than guess before the first one.

Finishing the plan

Once the checkpoint goes well, the rest looks a lot like the early visits: same table, same 20 to 30 minutes, alongside chiropractic care and guidance on how you sit, stand and move.

And how long does the relief last once the plan ends? We don't have reliable evidence on that, and we won't make up a number. What we can say is that the table was never the whole plan; the position and movement habits you leave with are meant to stay useful.

Soreness and side effects

Mild soreness the day after an early session isn't unusual. Mention it at the next visit.

Pain on the table is a different matter, and it means we stop and reassess.

Research has recorded worse outcomes, too. Side effects turned up in 7 of the 32 studies in the 2013 Cochrane review: increased pain, aggravated neurological signs and subsequent surgery. Report new numbness, weakness that's getting worse, or any change in bladder or bowel control straight away, and treat that last one as an emergency.

Between sessions

This part stays general on purpose, because the specifics come from your exam.

Every plan at Mecham Chiropractic includes advice on position and movement. If your week involves long stretches in a car, whether that's a drive to St. George or an afternoon crawling along I-15, ask how to break them up. Tell us what reliably sets off a flare, too. It's information the plan can use.

How this plan compares with other protocols

Decompression protocols vary, and the sources don't agree on a standard.

How three sources describe a course of decompression

University of Utah Health Plans, MP-053About 30 minutes, around 15 cycles10 to 15 daily treatments

A longer protocol isn't automatically a more careful one. Ours is the longest of the three, and more visits means more money when you're paying out of pocket, which is why the checkpoint matters more than the headline session count.

Questions people ask

Does spinal decompression hurt?

Spinal decompression isn't supposed to hurt, and real pain during a session at Mecham Chiropractic means stopping to reassess. Mild next-day soreness after early sessions isn't unusual, but new numbness, worsening weakness, or bladder or bowel changes need prompt medical attention.

How many sessions of spinal decompression will I need?

A decompression plan at Mecham Chiropractic is set after the exam, typically 20 to 30 sessions across 8 to 12 weeks. WebMD describes 20 to 28 treatments over 5 to 7 weeks, so counts vary, and any plan here is reconsidered at treatments 8 to 12.

How long is a spinal decompression session?

A spinal decompression session at Mecham Chiropractic lasts about 20 to 30 minutes on the DRX9000. Other sources differ: WebMD lists 30 to 45 minutes, and University of Utah Health Plans describes about 30 minutes with around 15 cycles.

Is it normal to be sore after spinal decompression?

Mild soreness the day after an early decompression session isn't unusual, and it's worth mentioning at the next visit. Pain during a session isn't normal; at Mecham Chiropractic it means stopping and reassessing before going any further.

What happens if decompression isn't helping?

When decompression brings no meaningful improvement by treatments 8 to 12, Mecham Chiropractic reconsiders the plan instead of finishing every scheduled visit. The checkpoint exists because the evidence for traction is weak, and nobody should keep paying for sessions that aren't working.

Dr. Cody Mecham checks whether your pain actually behaves like a disc problem before anyone talks about sessions. If decompression isn't a fit for you, that's the first thing you'll hear.
