Does Acupuncture Work? Understanding Evidence Based Healthcare
/One of the most common questions I hear is, ‘Does acupuncture work?’ The answer isn’t a simple yes or no—it depends on how we evaluate treatments like acupuncture, medication, or other therapies. This blog dives into the principles of evidence-based medicine, the challenges of research, and where acupuncture fits within this framework.
What does “Good Evidence” look like?
This pyramid explains it nicely. At the bottom we have ideas, opinions, editorials, anecdotal evidence; this is where your friend tells you about a treatment they had.
Right at the top of the tree are thorough studies; randomised controlled trials, systematic reviews, and meta-analysis. These trials often take years of work and lots of people – and they cost a huge amount of money! Think of them as having lots of friends who really know what they are talking about!
You might think this would give a pretty black and white picture - there’s a solution to a problem or there isn’t. But people are not mechanical objects, like cars. There’s rarely a “one size fits all “ resolution . What scientific studies show us is where there’s a noticeable difference, by clinical significance or statistical significance.
Clinical vs. Statistical Significance
Scientific studies help us to measure whether a treatment works in two key ways; statistical significance and clinical significance.
When evaluating treatments, it’s important to understand these two key concepts that help us assess their value.
• Statistical significance tells us whether a treatment’s effect is unlikely to be due to chance, based on data analysis. However, this doesn’t tell us how meaningful the effect is for patients. For example, a drug may show a noticeable difference in blood pressure, but the person may not feel the benefit.
• Clinical significance focuses on real-world impact. It asks whether the treatment makes a meaningful difference in a patient’s health or quality of life. For example, an acupuncture treatment relieving back pain so someone can return to work.
In short, statistical significance shows that a treatment works, while clinical significance shows how much it matters. Both are crucial for making informed healthcare decisions but neither mean something works for everyone.
Who Decides What’s Scientifically Proven?
Western medicine emphasises evidence-based medicine, a concept developed by Canadian epidemiologist David Sackett.
Back in 1981 he and his colleagues at McMaster University began publishing a series of articles in the Canadian Medical Journal advising physicians how to appraise medical literature. But an evidence-based medicine approach doesn’t rely solely on “the science” Sackett also advocated using the physician’s expertise, considering the individual needs of the patient, and the patients wishes.
Challenges in Evidence-Based Medicine
Once Sackett had given us a starting point for evidence-based medicine, you’d think understanding what works would be plain sailing . But no, evidence-based medicine is a bit of a minefield.
Firstly, there needs to be a hypothesis – an assumption that can be tested to see if it’s true or not.
Secondly, those trials cost money. Lots of it. And the closer you get to the top of the pyramid, the more it costs. Rigorous trials are expensive. That means that someone must benefit from doing them, whether in terms of prestige or financially. This could be the reason for the dominance of pharmaceuticals in medicine nowadays. It can also mean enough people will benefit from the trial. And THEN you must find a big enough chunk of similar folk to test your hypothesis on! A condition affecting a big chunk of the population is likely to attract more research funding than a rare illness.
The bottom line is that health isn’t a “one size fits all” issue. Even with rigorous research few medicines or therapies are guaranteed to work for everyone.
Addressing Misconceptions
A clinical trial with good results doesn’t mean something is guaranteed to work for you. Nor does a lack of clinical trials or meta-analysis mean that it won’t.
Let’s imagine a treatment is tested on knee pain. That could be acupuncture, a pharmaceutical intervention, or something else. If it is successful (either clinically or statistically significant) that’s unlikely to mean it will work for every case of knee pain. Nor does it mean that a similar intervention wouldn’t work for another area. such as elbow pain.
As American astronomer Carl Sagan put it well “Absence of Evidence is not Evidence of Absence” - remember though, that if something has been tested and found wanting, that is a different matter.
The existence of an evidence base can give you some confidence to make an informed decision, based on the likelihood of a positive impact against any potential side effects.
The downside
The expense and time required for good quality research means that only a fraction of the options available to you are “evidence based”. And even evidence based treatments take time to filter into common usage – usually about 17 years, according to the British Medical Journal.
Evidence Based Medicine in the U.K - NICE
What is NICE, and What Does It Do?
In April 1999 The National Institute for Clinical Excellence (NICE) was created to create consistent guidelines and end “postcode rationing “across the U.K. Now known as the National Institute for Health and Care Excellence, they continue to provide standard guidance for treatment of a range of conditions. This guidance is given in relation to the evidence base and to cost, but not the expertise of the physician or the individual patient, as David Sackett suggested.
Limitations of NICE Guidelines
Sadly, NICE hasn’t stopped the postcode lottery as each area manages its own funds. As an example, treatment offered to people struggling with fertility varies across the country. As I write this, NICE recommends 3 cycles of IVF for women struggling to conceive, but only one cycle is offered in Harrogate and the rest of North Yorkshire.
NICE and Acupuncture
NICE recommends acupuncture as an effective treatment for chronic pain, but cost constraints limit its availability to five group sessions delivered by healthcare professionals with basic training
In reality, this is likely to be a basic generic treatment, or protocol, delivered by a healthcare professional who has done a short course specifically for that protocol.
The Big Issue - do NICE Guidelines really deliver evidence based treatment?
It’s encouraging to see NICE recommending acupuncture, but their approach raises some important questions. Clinical trials typically test specific acupuncture points. These are usually chosen based on the recommendation of an experienced acupuncturist, or from text books. The acupuncture points will differ for each condition. However, NICE guidelines apply to ALL types of chronic pain without distinguishing between conditions. This blanket recommendation of “acupuncture” is akin to advising the use of “drugs” for a wide range of ailments without specifying which drug is appropriate for each condition.
Where Does Acupuncture Fit?
Back to our pyramid - Where does acupuncture fit in this picture? Is there any research at the top of the pyramid?
Researching Acupuncture is Tough, But….
Acupuncture is notoriously difficult to assess. Unlike drugs, there isn’t a single treatment for a specific problem . My blog about your diagnosis tells you more about this. Much depends on the skill of the acupuncturist. And there is no genuine placebo to test against. While “sham” acupuncture exists, there is still a connection with the body eliciting a response.
Yet good quality research exists for acupuncture. Despite the difficulties of assessing acupuncture’s effectiveness there is a body of evidence supporting its usefulness for a range of conditions.
Evidence For Acupuncture
Way back in 2002 the World Health Organisation reviewed clinical trials (top of the pyramid studies) researching acupuncture. They published a paper ‘Acupuncture; review and analysis of controlled clinical trials’. This said that acupuncture had been proven to be an effective treatment for a long and diverse list of conditions ranging from reactions to cancer treatment to turning a breech baby. (The full list is at the bottom of the page)
A Growing Body of Evidence
Since then, there has been a growing body of evidence for the effectiveness of acupuncture. For example, a meta-analysis of acupuncture for chronic pain was published in 2018.
This ‘top of the pyramid’ study looked at four common causes of chronic pain:
· nonspecific musculoskeletal pain
· osteoarthritis
· chronic headache
· shoulder pain
Including 20,827 patients, it concluded that acupuncture is effective for the treatment of chronic pain, with treatment effects persisting over time. The researchers found clear evidence that the effects of acupuncture persist over time with only a small decrease, approximately 15%, in treatment effect at 1 year
Why Chronic Pain?
Chronic pain is one of those appealing research areas, due to the number of people affected. According to the Office for National Statistics, muscular skeletal pain remains one of the main reasons for sickness absence from work.
Acupuncture: A Personalised Approach to Healing
Acupuncture, like many treatments, isn’t a one-size-fits-all solution. High-quality research supports its effectiveness for certain conditions, but health is complex, and treating you as an individual truly matters. The beauty of acupuncture lies in its ability to do just that—tailoring treatment specifically to you.
While I find research fascinating, my approach blends multiple sources of expertise: the skills honed during my three-year degree, over 2,000 years of recorded clinical practice, and my own hands-on experience. This combination allows me to provide care that is both informed and deeply personal.
Treating Jane’s Shoulder
Take Jane, for example. She came to me last week with a debilitating shoulder issue—pain and restricted movement that were affecting her life. Before beginning treatment, we had a thorough conversation about her symptoms and history. I also conducted pulse and tongue diagnosis, as well as palpation.
At the start, Jane could only lift her arm to about 45 degrees. By the end of the session, she could raise it nearly to 90 degrees, and her pain had noticeably diminished. She was astonished—not just by the results, but by the fact that they were achieved with just two needles: one in her foot and another below a knuckle.
