My spine is 'out of alignment' and needs adjusting
He'd been going to the same chiropractor for four years. Every visit, he was told his spine was 'out again.' Every visit, it was adjusted back. 'But it keeps going out,' he said, looking puzzled. I understood his puzzlement — because it almost certainly wasn't.
What Patients SayMy chiropractor told me my spine is out of alignment. I can feel it — one side feels tighter than the other. Can you adjust it back into place?
Where Did This Come From?
The concept of spinal "subluxation" — the idea that vertebrae shift out of alignment and need manual correction — is the foundational theory of traditional chiropractic, dating back to the 1890s. It's been the central selling point of the profession for 130 years. The concept is intuitive, the diagnosis (via X-ray "analysis" or manual examination) feels concrete, and the promise of realignment is compelling.
The problem is that the scientific evidence for spinal subluxation as a clinical entity — causing pain, affecting health — is essentially absent. Major chiropractic organisations themselves have moved away from subluxation theory in recent decades, acknowledging it's not well-supported. But in practice, plenty of clinicians still use the language because patients respond to it, and because alternatives are harder to explain.
What the Science Actually Says
Vertebrae cannot "shift" out of alignment and then be manually repositioned without surgical intervention. The joints, ligaments, and muscles of the spine hold vertebral alignment extremely firmly — so firmly that significant trauma (like a car accident) is usually required to dislocate a vertebra. A gentle manual manipulation cannot "realign" what isn't misaligned in the first place.
What can manual therapy do? Spinal manipulation does have a modest evidence base for short-term pain relief in some forms of low back pain. But the mechanism isn't realignment — it's more likely related to neurological effects (pain gating, muscle relaxation), movement of trapped synovial fluid, and psychological factors (the therapeutic encounter, the "treatment" experience). X-rays used to assess spinal "alignment" for chiropractic purposes consistently show poor reliability and validity.
Two practitioners examining the same X-ray frequently disagree on subluxation findings. This is not how a reliable diagnostic tool behaves.
The Verdict
Spines don't get "out of alignment" in the way described, and manual manipulation doesn't realign them. The treatment may have short-term benefits through other mechanisms, but the structural explanation offered is not scientifically valid.
What To Do Instead
- If manual therapy helps your pain, you don't have to stop — just don't accept the explanation uncritically
- Be wary of practitioners who insist on repeated treatments indefinitely to "maintain alignment" — evidence for maintenance chiropractic treatment is very weak
- Seek a second opinion from an evidence-based clinician if you're being told you have a serious alignment problem requiring extensive treatment
- Address the underlying cause of your symptoms (muscle imbalance, movement dysfunction, pain sensitisation) rather than chasing an alignment myth
Yellow Flags — Worth Monitoring
- A practitioner who shows you X-rays to demonstrate misalignment and recommends many weeks of pre-paid treatment — this is a significant red flag for over-treatment
- Symptoms that temporarily improve with manipulation but never resolve — consider whether you're treating the cause or just the symptoms
Red Flags — Get Checked Immediately
- Any practitioner proposing neck manipulation when you have neurological symptoms — cervical manipulation carries a small but real risk of vertebral artery dissection
- Manipulation after a recent trauma or with known osteoporosis — fracture risk
