862,000 people studied: no sign that neck manipulation causes torn arteries
What happened
For years there has been an argument about neck manipulation. It is the quick, sharp movement a chiropractor sometimes uses to treat neck pain. The worry is about something called a cervical artery dissection. That is a small tear in the wall of an artery in the neck. It is rare, but it can lead to a stroke. On 18 September 2026, a study was published in the journal Chiropractic & Manual Therapies that looked at this question using a very large set of health records. Researchers from University Hospitals Cleveland Medical Center, Case Western Reserve University School of Medicine, Cleveland Clinic and Duke University studied more than 862,000 adults in the United States. All of them had gone to a healthcare professional with new neck pain or a new headache. The team then built two carefully matched groups of more than 431,000 people each. One group had neck manipulation from a chiropractor. The other group was given ibuprofen instead. They counted how many people in each group had an artery tear within 30 days.
Why this matters
Neck pain is extremely common. Most people get it at some point, and many try manual treatment for it. The question of whether that treatment is safe has been genuinely hard to answer. Artery tears are rare enough that you would need an enormous randomised trial to spot a difference, and no one is going to run a trial where they deliberately risk a stroke. So researchers have had to work with records instead. Earlier studies produced mixed and sometimes alarming results, and the debate has run for decades. There is also a trap hiding in the data, and it is an important one. A tear in a neck artery often causes neck pain and headache before it causes a stroke. So someone may already have a tear, go to a chiropractor because their neck hurts, and have a stroke days later. The manipulation looks like the cause. It may simply have been the reason for the visit. That is why this study compared chiropractic care with ibuprofen, rather than with nothing at all. Both groups had come in with the same kind of problem.
What the evidence actually says
In the chiropractic group, there were 31 cases of artery dissection within 30 days. In the ibuprofen group, there were 58. So the group that had neck manipulation had fewer tears, not more. The researchers concluded there was no sign of added risk. Co-author Christine Goertz said: "This study is some of the best evidence yet that the answer to that question is yes" - meaning yes, chiropractic neck care for pain appears to be safe. Now the honest caveats, because they matter. This is not a randomised trial. It is an analysis of health records, and matched groups are never perfectly matched. People who choose a chiropractor may differ from people who take ibuprofen in ways the records cannot capture. The study was published in Chiropractic & Manual Therapies, a journal that specialises in this field. That does not make the findings wrong, and the research team came from several well-regarded medical institutions. But it is a fair thing for a reader to know when weighing up the result. The researchers themselves were careful. They stressed that clinicians should stay alert for unusual headaches, neck pain that does not feel like ordinary neck pain, and any neurological symptoms - because those can be the early signs of a tear that is already there.
Practical advice
Ordinary neck pain and ordinary tension headaches are usually nothing serious, and they usually settle. But some symptoms need urgent attention, whatever treatment you are having. Call 999 if you have any sign of stroke. Use the FAST test: Face dropping on one side, Arms that cannot be lifted, Speech that is slurred, Time to call 999. Contact NHS 111 or your GP urgently if your headache is the worst you have ever had or came on suddenly like a thunderclap, if you have neck pain with dizziness, double vision, difficulty swallowing or slurred speech, or if neck pain follows a car crash or a fall. If you do see a chiropractor, osteopath or physiotherapist, tell them about any of those symptoms before treatment starts, not after. In the UK, chiropractors must be registered with the General Chiropractic Council and osteopaths with the General Osteopathic Council. You can check a practitioner's registration free on those regulators' websites in under a minute. It is worth doing. For everyday neck pain, the boring advice still works: keep moving gently, avoid long periods in one position, and use ordinary painkillers if you need them and they are suitable for you. Your pharmacist can tell you whether ibuprofen is a good choice for you, as it does not suit everyone.
What to know
A study of more than 862,000 adults found 31 artery tears within 30 days among people who had chiropractic neck manipulation, compared with 58 among a matched group given ibuprofen. There was no sign that manipulation raised the risk. This is not the final word. It is a records-based study, published in a journal specialising in the field, and it cannot prove cause and effect. But it is one of the largest looks at the question so far, and it points in a reassuring direction. The practical point the researchers make is the one worth remembering: a torn artery can announce itself as neck pain or a strange headache before anything else happens. If your symptoms feel unusual or come with dizziness or slurred speech, that is a reason to seek help quickly - regardless of who you were planning to see.
