Dry needling vs Acupuncture - what's the difference?
/I often get asked this question and as a registered acupuncturist and a physiotherapist who uses dry needling, I feel I can give an un-biased authentic view and explanation of the two.
What is dry needling?
Also known as myofascial trigger point needling, it uses a filiform needle (the same used in Acupuncture) to be inserted into the trigger points. Trigger points or myofascial trigger points are essentially sites of irritation within muscle fibres, which can form a ‘muscle knot’ or band of tightness or discomfort.
This practice was first discussed by Janet Travell in the 1940s, in her book “Myofascial Pain and dysfunction: the trigger point manual”.
It is mostly used for pain eg knee pain, shoulder pain, low back pain, neck pain.
These days you will find some physiotherapists, chiropractors or massage therapists who will perform dry needling as an adjunct to their treatment after doing a short course.
What evidence is there for Dry Needling?
To date there are varying degrees of evidence for dry needling; although the body of evidence is growing. There is some evidence for dry needling for localized musculoskeletal pain conditions; albeit short term of less than 6months. There is a need for greater quality research with larger scale trials as generally research is deemed inconclusive.
What is Traditional Acupuncture?
Traditional Chinese Acupuncture can be dated back for over 2000 years; making it one of the oldest health practices recorded.
Works by aiming to normalize the flow of energy, known as ‘qi’, and blood throughout the body to help stop any unwanted blockages along the body’s pathways, known as ‘meridians’. These blockages usually manifest as potential symptoms or conditions. It is the aim to restore the natural flow of balance to the body.
What evidence is there for Acupuncture?
McDonald and Janz’s The Acupuncture Evidence Project (2017), is a review of the evidence supporting the efficacy of acupuncture in varying conditions. There is strong evidence (quality is moderate or high with reviews consistently showing statistically positive effects) for allergic rhinitis (perennial and seasonal), chemotherapy-induced nausea and vomiting (with anti-emetics), chronic low back pain, headache (tension headache or chronic), knee osteoarthritis, migraine prevention, postoperative nausea and vomiting and postoperative pain.
There is moderate evidence (moderate to high quality, although insufficient to draw firm conclusions) on varying other conditions eg acute low back pain, anxiety, hypertension, insomnia, lateral elbow pain, menopausal hot flushes, temporomandibular joint pain (TMJ dysfunction), stroke rehab, smoking cessation.
He also identifies many conditions that currently have low level of efficacy and require more high quality and level of evidence based research.
Koppleman (2018) gives a good summary of an overview of the scientific evidence thus far, and puts it into context in the current medical system.
Similarly to dry needling, the body of evidence of research is continuing to grow.
Is dry needling acupuncture?
Dry needling can be viewed as a form or a small fraction of Acupuncture. Trigger points in traditional Chinese Medicine are viewed as what we term Ashi points. Ashi points are classified as palpable tender points. I often tell patients that true traditional acupuncture is dry needling plus so much more.
Generally dry needling is used only for pain conditions, whereas acupuncturists use traditional acupuncture for all health conditions.
So be aware: some therapists will claim to do acupuncture or Western acupuncture but really it is just dry needling. Don’t get me wrong; dry needling can still be of great benefit (especially if done in conjunction with some great manual therapy and prescribed exercises), but as long as you know ‘what you’ve signed up for’ and that it is not traditional acupuncture. I feel this is often why I hear patients say that “acupuncture does not work”; because in fact they have not had it.
Benefits of seeing a registered acupuncturist:
Increased training (dry needling requires a minimum of 16 hours for allied health practitioners. Acupuncturists require a minimum bachelor 4 years degree or a 3 years post-graduate Masters Degree in Acupuncture). Physiotherapists in Australia can do post-graduate certificates in Western Acupuncture, however this does not make them an acupuncturist. The title of acupuncturists are strictly for those registered with the Chinese Medicine Board of Australia (CMBA) and have completed the intense training as mentioned above.
Less pain, increased techniques.
Stricter safety and infection control.
Generally more holistic nature in which acupuncturists aim to help balance the body, mind and spirit and treat not only the symptoms, but also the underlying perceived cause of the problem.
Use for varying conditions or ailments whereas Dry Needling is generally only used for pain.
In a nutshell:
Dry needling is an adjunct treatment, usually used for pain conditions by qualified allied health professionals like physiotherapists.
Acupuncture is the holistic approach of treatment for the whole body, including body, mind and spirit. It can be applied in adjunct to target various conditions, not just pain. Acupuncturists are registered professionals with a minimum Bachelor’s degree in training and are regulated by the Chinese Board of Medicine.
Both have some evidence of effectiveness. To date, there is stronger evidence for acupuncture for specific conditions.
Know what treatment you are having, as there is a difference between the two. Do not be afraid to ask your therapist.
Why not try our highly qualified physiotherapists for the dry needling or the dually qualified physiotherapists/acupuncturists (there are only a handful of these in the state) at the clinic for a more holistic approach?
