You’re not crazy for asking this.
You’ve probably seen a headline like:
“Person goes for a neck adjustment – later has a stroke.”
…and now you’re thinking, “Hang on… am I risking my life just to fix my neck?”
So let’s sit down, have a metaphorical cup of tea, and walk through what the research actually says – not the clickbait.
A few things have fuelled this:
individual stories where a person had a neck manipulation and later suffered a stroke. Some of these show clear vertebral or carotid artery dissections (tears in the artery wall).
tragic cases understandably make news. They’re emotive and stick in people’s minds.
it’s intuitively scary that we’re moving a mobile part of the body near arteries that go to the brain.
Case reports are important – they tell us what canhappen – but they cannot tell us how oftenit happens, or whether the treatment truly causedthe problem versus arriving in the middle of something that was already happening.
That’s where the big population studies come in.
Before we talk strokes, it helps to know what a chiropractor is actually doing.
In a typical cervical adjustment:
That pop (cavitation) is the same basic physics as cracking your knuckles: a rapid pressure change forms and collapses a tiny gas bubble in the joint.
The goal is to:
Get stiff joints moving, calm overprotective muscles and nerves, and reduce pain.
Most people walk out feeling looser or at least “different”. Some feel mild soreness for a day or two – like you’ve done a new workout. In large trials of spinal manipulation for back and neck pain, minor side effects(soreness, stiffness, temporary headache) are fairly common, but serious complications are rare.”
This is the bit most people never see, because it’s not very clickbaity.
A large population-based study from Ontario looked at people who had a specific type of stroke called vertebrobasilar artery (VBA) stroke, and checked whether they’d seen a chiropractor or a GP beforehand.
Here’s the interesting bit:
The authors concluded:
The increased risk of VBA stroke after both chiropractic and GP visits is likely due to patients with early symptoms of arterial dissection(neck pain/headache) seeking care – notbecause chiropractic treatment itself is causing the strokes.
In other words:
So the visit and the stroke are associated, but the visit didn’t necessarily causethe stroke.
A more recent analysis looking at cervical artery dissection and chiropractic care has said something similar: there’s a small statistical association, but the data don’t prove causation. The relationship can be explained by people with early dissection symptoms seeking care for neck pain/headaches.
There’s also a 2025 observational study comparing chiropractic and medical care for neck pain that again describes serious adverse events as uncommon, with most events mild and transient.
Here’s the honest, grown-up answer:
A 2017 overview of reviews on spinal manipulation found that:
Another line of research:
Do we know the exact risk number for stroke? No – and anyone who pretends they do is guessing. But the combined picture says:
Serious complications like stroke after neck manipulation are very rare, but likely not zero.
That’s the nuance: extremely low risk, not no risk.
Recent papers have looked at howmanipulation couldcause a problem, in theory, especially if arteries are already at risk.
Those authors are not saying “never treat the neck”. They’re saying:
This is exactly why modern guidelines and frameworks for manual therapy spend so much time on vascular red flagsand safe practice.
Zooming out from just strokes:
A more recent 2019 BMJ review on spinal manipulative therapy for low back pain described serious adverse events as uncommon, with the majority of reported problems being minor and temporary.
Again: not “never”, but low frequency, particularly when clinicians follow good screening and technique guidelines.
If we define “safe” the way we do for most healthcare:
From that perspective:
If you’re otherwise healthy, have been properly screened, and are being treated by a registered, evidence-aware chiropractor, the absolute riskof a catastrophic event appears to be very low.
But here’s the key: youget to decide what level of risk you’re comfortable with, once you’ve had it explained clearly.
Some people sit closer to the “let’s be more careful” end of the spectrum.
Risk factors that may increase concern for cervical artery dissectioninclude:
If you’ve got anything on that list, or new neurological symptoms, a good chiropractor will:
Hit pause on neck manipulation and send you for urgent medical assessment– not more adjusting.
Modern frameworks (like the IFOMPT cervical framework and Australian guidelines for cervical manual therapy) emphasise exactly this kind of vascular screening before neck treatment.
Here’s what good practice looks like in real life.
Expect questions like:
If neck pain plus odd neurological symptoms are present, they should be thinking “rule out artery issues first”, not “let’s adjust and see”.
This includes:
Not every neck needs a fast thrust. Alternatives include:
In higher-risk or more anxious patients, many chiropractors simply avoid cervical thrustsand use alternatives.
You should get a clear, adult conversation covering:
Alternatives (different techniques, physio, exercise-only approaches, medication, watchful waiting, etc.)
You’re looking for something more thoughtful than “oh, it’s rare, don’t worry”.
A good clinician will happily talk about mobilisation, exercises, thoracic work, or co-management.
They might say, “For you, I’d prefer gentler techniques” – which is fine.
You should get a clear list of expected mild reactions and what serious symptoms would warrant urgent care (speech trouble, severe headache, sudden weakness, etc.).
