Inversion table vs traction

Is an inversion table traction?

Yes, in the way the health sources use the word. Cleveland Clinic says the idea is that hanging upside down "allows gravity to briefly take the pressure off the nerves of your spine". WebMD describes the aim as temporarily creating more space between vertebrae. Healthline says inversion shifts gravity so it eases pressure on the back "while also providing traction for the spine".

So the real question is not "table or traction". It is which way of applying a pulling force, if any, suits you, and who is in control of it.

How the approaches differ

Inversion table. Gravity and your own body weight supply the pull. Cleveland Clinic says you strap in, tilt back gradually, and control the angle and speed yourself. Both Cleveland Clinic and WebMD advise having someone nearby the first time. A table needs floor space to tilt; see how much space a table needs.

Clinic traction. A 2026 randomized trial in Scientific Reports describes mechanical traction as a clinic technique, in that study using a device to apply "a controlled and measurable traction force". The researchers set the force at 25% of body weight and raised it with tolerance, up to 50%. So a clinician sets the dose, not the patient. The same paper says mechanical traction is widely used (about 41% of clinicians in the UK and 77% in the US, per its sources) but that its effectiveness "remains uncertain", with trials limited by weak blinding, small samples and varied protocols.

Home traction devices. We did not find a health authority page describing lumbar belts or over-door neck kits, so we say nothing about how they work, how much force they apply or how much room they need. Check the maker's instructions, and ask a clinician before using one. We do not recommend a traction device, because we could not verify any maker's specs or claims.

The practical difference is who sets the force. With a table it is you, through the angle. With clinic traction it is the clinician. Evidence for both is limited.

What NICE says about traction

NICE guideline NG59, "Low back pain and sciatica in over 16s: assessment and management", lists traction under manual therapies. Recommendation 1.2.6 reads: "Do not offer traction for managing low back pain with or without sciatica." It dates from 2016. The guideline is about care offered in health services, and it does not mention inversion tables by name in the section we read. We are not saying NICE has judged inversion tables. We are saying the national guidance does not support traction as a back pain treatment.

What the evidence says about inversion

• Cleveland Clinic: "The research is mixed", there is "limited quality evidence" and most studies have been small.
• WebMD: evidence is mixed, it is "probably not an effective long-term treatment", and studies suggest inversion works no better than sham treatment. It adds that injuries are fairly common, most often from operator error.
• Healthline: studies are inconclusive. It quotes Mayo Clinic that most well-designed studies found inversion therapy ineffective, and says there is no evidence a table is better than inverting standing or sitting.

If you are weighing the two

1. Ask a doctor or physical therapist. Cleveland Clinic suggests trying inversion in physical therapy before buying a table.
2. Remember the pressure effects. WebMD says inversion slows the heartbeat, raises blood pressure and increases eye pressure.
3. Compare it with a lower-angle option. See inversion table vs back stretcher.
4. If you still want a table, check the maker's weight and height limits first.

Common questions

Is inversion therapy the same as traction? The sources we read say inversion is a form of traction. It uses gravity instead of a device that pulls.

Does an inversion table work better than a traction device? We found no source that compares them. The evidence for inversion is mixed and limited.

Do doctors recommend traction for back pain? NICE NG59 says not to offer traction for low back pain, with or without sciatica. Your own doctor can tell you what applies to you.

Is inversion safe? Not for everyone. Cleveland Clinic lists conditions that call for a doctor's advice first, including high or low blood pressure, heart conditions, glaucoma, pregnancy and stroke.
