Traction therapy
Decompression is a computer controlled traction table that applies a gentle, cyclical pull to the spine. The intention is to reduce pressure on a disc and the nerve root beside it. It suits a specific group of presentations, and the examination decides whether yours is one of them.
What the table does
You lie on the table in a harness and the machine applies traction in cycles, pulling to a set tension and then easing off repeatedly. The cycling matters: a constant pull tends to make muscles brace against it, while repeated pull and release is better tolerated and is the pattern these tables are built around.
The proposed mechanism is a reduction in pressure inside the disc, which may allow a bulge to retract slightly and take load off the nerve root. That is the rationale rather than an established certainty, and it is the honest way to describe it. Most people feel a stretch and nothing more.
It is considered where the examination points at a disc with nerve involvement, which usually means the leg pain pattern or the findings described on the disc page. Where the testing points at a joint or a muscle instead, this is not the right tool and loaded work usually is.
On the table
The examination has to point at a disc with nerve involvement before this is offered at all.
Positioning and tension are set for your size and presentation rather than to a default setting.
Around twenty minutes of pull and release, during which most people feel a stretch and nothing sharp.
Straight leg angle, reflexes and strength are rechecked rather than relying on how the sessions felt.
Honest limits
It cannot be presented as guaranteeing pain relief, repairing a disc, permanently correcting the spine, preventing degeneration, or removing the need for surgery. Those are the exact claims that regulators single out, and none of them is made here. It may reduce pain and improve walking for some disc related cases.
It is also not a standalone answer. Where it helps, it usually helps alongside advice about sitting and loading, and alongside strengthening work that changes what the back tolerates afterwards. A course without that tends to buy a quiet period rather than a durable change.
Courses are proposed with a retest point rather than sold as a block of sessions to be completed regardless. If the markers have not moved by then, that is said plainly and the plan changes, which is the same standard described under what it costs and how plans work.

Anything specific to you belongs in the examination rather than on a page.
They retested part way through the course and said the markers had moved, so we finished it. No pressure either way.
Told me upfront which claims about this machine are not supported, which made me trust the rest of it more.
Checked that the disc findings actually fitted before quoting a course, rather than selling it to everybody.
Paid session by session rather than a block upfront, which mattered when we decided to stop at eight.

Next step
The examination establishes whether a disc with nerve involvement is actually the picture, which is the only basis on which a course is proposed.
General information, not medical advice. What applies to you is decided at the examination.
