Physio 'dry needling' and acupuncture – what's the difference and what does the evidence say?

All physiotherapists trained in either acupuncture or dry needling meet safety standards which are viewed as within scope by the Australian Health Practitioners Regulatory Agency^[9] and the Physiotherapy Registration Board^[10]. These standards cover the level of training required, registration to practice and safety standards that include needle safety and hygiene to protect the public.

Minor reported side effects^[11] related to acupuncture including pain and bleeding or bruising from needle insertion are fairly common. But major adverse events – pneumothorax (collapsed lung), excessive bleeding, prolonged aggravation – are rare.

What’s needling good for?

Research into the effectiveness of acupuncture and dry needling is variable. Some studies show comparable results between dry needling and acupuncture, while others show more favourable results for one or the other depending on the condition being treated.

A review^[13] that assessed the effects of acupuncture and dry needling for the treatment of low-back pain found they may be useful add-on therapies but could not make firm conclusions due to a lack of quality trials.

Another review^[14] reported the growing popularity of dry needling world wide and across disciplines and points out that many questions still remain regarding the use of needling.

For migraine^[15] and tension^[16] headaches, experts say acupuncture seems to reduce the frequency and intensity of attacks – though more research is needed to compare it to other treatments.

Acupuncture and dry needling may reduce pain and improve function for people with neck pain^[17]. A systematic review found significant differences between acupuncture and “sham acupuncture” (which is performed away from acupuncture points) when used to treat certain types of chronic pain^[18]. However, some research only shows small and temporary^[19] relief for neck pain with dry needling.

Results from randomised control trials support the use of needling for shoulder pain^[20], tennis elbow^[21] and osteo arthritic knee pain^[22]. But a recent systemic review of research reported only weak evidence to support needling to treat plantarfasciitis and chronic ankle instability^[23].

Not just for sporting injuries

Similarly, small randomised control trials have shown acupuncture and dry needling might reduce problematic jaw pain^[24] (temporo mandibular disorder^[25]) and improve mouth opening.

Systematic reviews have reported needling and acupuncture were safe and effective recommendations for the treatment of broad conditions of tendinopathy^[26] (the breakdown of collagen in tendons) and fibromyalgia^[27] (chronic pain in the muscles and bones).

For women’s health, acupuncture has been shown to be effective for reducing pain with periods^[28], compared to no treatment or non-steroidal pain relief medications – but the research had design limitations.

Though widely used^[29] in pregnancy, research into the use of acupuncture to induce labour^[30] reports it may increase satisfaction with pain management and reduce pain intensity. But it may have little to no effect on the rates of caesarean or assisted vaginal birth.

In summary, it appears needling techniques – whether dry needling or acupuncture – generally show positive effects over no treatment or “sham” treatments, but more research and high quality trials are needed.

Just one part of a treatment program

Needling may be useful^[31] as part of multimodal care – that is, when more than one treatment^[32] is used in conjunction to treat a problem.

Physiotherapists may combine needling therapies with exercise prescription, hands-on care including massage, mobilisations and manipulations, and taping techniques. They may also employ therapies that apply external energy such as ultrasound, laser, transcutaneous (under the skin) electrical nerve stimulation and biofeedback.

Finally, while the various needling techniques all use a filiform needle (with a solid filament as opposed to a hollow bore needle), the styles with each can be quite different. Ask what style of needling is being employed to treat you, and if you have a history of finding one style works better for you, discuss this with your practitioner.
