Evidence
Every week I see what acupuncture can do: migraines that stop, pain that eases on the table, sleep that returns. Research works with averages across hundreds of people, using the same points for everyone. It cannot capture the one person in front of me.
Before Chinese medicine, I spent fifteen years as a research scientist. So here is both: what the studies show, where the evidence is good, where it is limited, and what my clients tell me.
For those who want to understand more, here is the detail. Read on ↓
The largest analysis so far pooled the original data of 20,827 patients from 39 randomised trials, in back and neck pain, shoulder pain, chronic headache and osteoarthritis. Acupuncture worked better than no acupuncture, and better than sham (fake) acupuncture. The difference from sham was smaller, but real, and the benefit lasted: a year later, the effect had decreased only a little (Vickers and colleagues, Journal of Pain, 2018).
In 2021, NICE, which advises the NHS, included acupuncture in its guideline for chronic primary pain: pain with no clear underlying cause, such as chronic widespread pain. It says a single course of acupuncture can be considered.
A Cochrane review of 22 trials with almost 5,000 people looked at acupuncture to prevent migraine. After treatment, migraine frequency halved in 41 of every 100 people having acupuncture, compared with 17 of every 100 on usual care. Against preventive drugs, acupuncture did at least as well, with fewer side effects. The evidence was rated moderate quality.
NICE recommends considering a course of up to 10 acupuncture sessions over 5 to 8 weeks to prevent chronic tension-type headache, and to prevent migraine when the usual medicines are unsuitable or have not worked.
Many physiotherapists, in the NHS and in private practice, use dry needling: fine acupuncture needles placed into tight, painful points in muscle, often called trigger points. It is now a standard tool in physiotherapy for neck, shoulder and back pain, and for sports injuries.
NICE’s guideline on chronic primary pain names acupuncture and dry needling together, as a treatment that can be considered.
I use dry needling too, when a muscle is knotted and needs releasing directly, alongside distal needling, neoclassical acupuncture, electro-acupuncture and myofascial release. How I treat pain →
Trials ask whether acupuncture works. Another line of research asks how. With brain scans and anatomy, it shows that a needle is not a placebo pill: it is a real signal to the nervous system.
Brain scans (fMRI and PET) show that needling changes activity in areas that process pain, emotion and stress. In one study at the University of Michigan, women with fibromyalgia had eight sessions of acupuncture. PET scans showed that acupuncture increased the brain’s capacity to use its own pain-relieving opioid system, in regions that process and dampen pain, and the larger this change, the less pain they felt. Sham needling eased pain too, but through a different mechanism in the brain (Harris and colleagues, NeuroImage, 2009).
This is the part of the research I find most convincing as a scientist: we can now see, on a scan, the nervous system respond to the needle.
Dr Poney Chiang, PhD in biomedical research at the University of Toronto and an acupuncturist, maps acupuncture points onto the nerves that lie beneath them. Many classical points sit where nerves come close to the surface, and his current research uses MRI to relate scalp points to the brain regions under them. His work explains, in the language of neuroscience, why the old points work.
Dr Narda G. Robinson, DO, DVM, a leading teacher of medical acupuncture, describes acupuncture as neuromodulation: the needle acts on motor, sensory and autonomic nerves, and the result depends on which nerves are reached and how they are stimulated. Dry needling, electro-acupuncture and acupressure are all ways of giving that signal.
She shows how many classical points sit exactly where the nervous system is most responsive. Trigger points, for example, form mostly in the middle of a muscle belly and where muscle meets tendon, where specialised nerve endings cluster. Points on the back share their spinal nerve supply with the organs beneath, so tension found by palpation along the spine can point to what is happening deeper inside. This is why, in my sessions, careful palpation guides where I place each needle (Robinson, Interactive Medical Acupuncture Anatomy).
Dr Ingrid Wancura-Kampik’s Segmental Anatomy: The Key to Mastering Acupuncture, Neural Therapy and Manual Therapy maps how each spinal nerve supplies its own segment of skin, muscle, bone and inner organs. Acupuncture points line up with this map. A needle in the skin or muscle of one segment reaches the same spinal level as the organs it shares nerves with. That gives a clear anatomical reason why a point on the back or the abdomen can influence digestion, breathing or pain deeper in the body.
Matt Callison, author of Sports Medicine Acupuncture (2019) and one of my teachers, has spent over 20 years dissecting cadavers to map exactly where motor nerves enter each muscle. These motor points match many classical acupuncture points, and needling them, often with electro-acupuncture, is central to how he treats sports injuries and rehabilitation. It is one of the clearest bridges between Chinese medicine and Western anatomy.
Dr Donald Kendall, an engineer turned doctor of Oriental medicine who did acupuncture research at UCLA, went back to the original Chinese texts in The Dao of Chinese Medicine (Oxford University Press, 2002). He argues that the classics describe a physical body: mai are blood vessels, qi is closer to the vital air and nourishment they carry than to a mysterious “energy”, and acupuncture points sit at nodes where nerves and blood vessels meet. In his reading, the ancient doctors were careful anatomists, and their medicine fits with modern physiology.
Professor Tianjun Wang, PhD, guest professor at Nanjing University of Chinese Medicine and one of my teachers, works with scalp acupuncture for the brain: stroke, Parkinson’s, headaches, anxiety and depression. His book, Acupuncture for Brain (Springer, 2021), brings together the classical theory and modern research on how needling the scalp influences the brain.
Simply: fascia is the thin web of connective tissue that wraps every muscle and organ. When I gently turn a needle, this tissue grips it and winds around it, a little like spaghetti on a fork. The tissue is stretched, and the cells inside it respond. This is one reason why acupuncture can release tightness and ease pain in the area being treated.
In more detail: Dr Helene Langevin and her team at the University of Vermont showed that rotating a needle increases the force needed to pull it out, because connective tissue winds around it, not because the muscle contracts (FASEB Journal, 2002). In a second study, about 80% of acupuncture points in the arm lay on planes of connective tissue between or within muscles (Anatomical Record, 2002). Once the tissue is wound around the needle, small movements stretch the surrounding network, and the fibroblasts, the cells that build and maintain fascia, change shape and send chemical signals. A 2025 review describes fibroblasts as key cellular targets of acupuncture.
To be honest about the limits: this is strong evidence for local effects, such as tissue tone, mobility, circulation and pain signals. It does not prove that fascia explains everything acupuncture does, or that meridians are simply fascial planes. Fascia works alongside the nervous system, not instead of it.
Sham acupuncture is not a sugar pill. In many trials, “sham” means shallow needles at other points, or blunt needles that press on the skin. Both still stimulate the body, so they are not a true inactive control. This is why acupuncture often beats sham by less than it beats no treatment, and why researchers still argue about how much is “specific” effect.
Some NICE guidance says no. For low back pain, with or without sciatica, and for osteoarthritis, NICE currently advises against offering acupuncture. Their reasons are partly about how acupuncture compared with sham in trials, and partly about cost to the NHS. Other reviews, including the large analysis above, read the same data more positively.
Many conditions are less studied. For anxiety, menopausal hot flushes, IBS, hay fever and sleep, there are promising trials and reviews, but fewer large, high-quality studies. I treat these often, and many clients feel the difference, but the research is not yet as strong as for pain and headaches.
My way of working is harder to test. Most trials use set points for everyone. In practice, I combine acupuncture with bodywork, cupping or herbs, adjusted to each person, each time. That is closer to real-life care, but it is not what most trials measure.
Research tells us what happens across hundreds of people. This is what it can look like for one person.
I had been suffering from visual migraines for about 3.5 years. After having my vision checked and receiving medication from my family doctor, I had pretty much accepted that I would have to live with it.
She gently suggested that stress might be a factor and that acupuncture might help. I decided to give it a try, not expecting much. To my surprise, after just one session, I went about a year and a half without any symptoms!

I had chronic pain in my shoulder blade, neck and underarm for 18 months. I was attending physio appointments every month, but with no improvement.
Elzbieta treated me with electro-acupuncture, and within a few moments all the pain I had for nearly two years was gone. I couldn’t believe it! She also gave me lots of dietary advice for my IBS. I am very grateful and happy to finally live with no pain.

Ela is the best. Everything she does, she does with her whole heart, and she always helps. I am always happy with her work and her help.
She helped me when I had problems with my digestion, and she did everything so that the problem would not come back. At the threshold of menopause, she helped me cope with my emotions and mood swings. She helped me when something happened to my spine and I was climbing the stairs on all fours. She helped our daughter learn to cope with stress before important exams.
We know we can always count on her. We live quite far away, but it is really worth travelling from Manchester to see her, because she will always do everything to help, and to make sure the problem does not come back. I recommend her with all my heart.

In the hands of a trained, registered practitioner, acupuncture is very safe. A UK study followed 34,000 treatments by traditional acupuncturists and found no serious adverse events. Minor effects, such as a small bruise or feeling tired or light-headed afterwards, are the most common, and they pass quickly (MacPherson and colleagues, BMJ, 2001).
I use sterile, single-use needles, and I am registered with the ATCM and fully insured.
Research tells me what works on average. Your body tells me what works for you. I use both. I will always tell you honestly what I expect, and if acupuncture is not the right choice for you, or you need to see your GP first, I will say so.
