Acupuncture

Acupuncture has been used successfully in China for thousands of years.  Its acceptance into the Western medical system has been hindered due to the lack of scientifically validated studies. But that has been changing rapidly in recent years and now we have access to The Acupuncture Evidence Project  (McDonald J, and Janz S, 2017).  

 

“It is no longer possible to say that the effectiveness of acupuncture is because of the placebo effect, or that it is useful only for musculoskeletal pain” (Janz & McDonald)

 

The Acupuncture Evidence Project has found evidence for the effectiveness of acupuncture for 117 conditions, with stronger evidence for acupuncture’s effectiveness for some conditions than others. Acupuncture is considered safe in the hands of a well-trained practitioner and has been found to be cost effective for some conditions. The quality and quantity of research into acupuncture’s effectiveness is increasing.

Background (to the compilation of the Evidence Project)

(Quoted from the Plain English copy by S. Janz & J. McDonald)

“Acupuncture originated in China and is now practised throughout the world.  Although acupuncture has been practised for thousands of years, evidence of its effectiveness is still controversial. The Australian Acupuncture and Chinese Medicine Association Ltd (AACMA) identified the need for an updated review of the evidence with greater rigour than was possible in the past and commissioned The Acupuncture Evidence Project. We searched the literature with a focus on systematic reviews and meta analyses (the highest form of evidence available). We sorted the evidence to identify which conditions acupuncture has been found to be most effective for. We also looked for evidence of acupuncture’s safety and cost-effectiveness, and we reported how the evidence for acupuncture’s effectiveness has changed over an eleven-year time-frame. Key results Of the 122 conditions identified, strong evidence supported the effectiveness of acupuncture for 8 conditions, moderate evidence supported the use of acupuncture for a further 38 conditions, weak positive/unclear evidence supported the use of acupuncture for 71 conditions, and little or no evidence was found for the effectiveness of acupuncture for five conditions (meaning that further research is needed to clarify the effectiveness of acupuncture in these last two categories). In addition, research showed that acupuncture was cost effective for 10 conditions, and is safe in the hands of a well-trained practitioner. The level of evidence has increased over the 11-year period of this study for 24 conditions. Placebo-controlled clinical trials consistently underestimate the true effect size of acupuncture (which means that acupuncture is more effective than the type of trials used in this review show), yet they have still demonstrated National Health and Medical Research Council (NHMRC) Level I evidence for the effectiveness of acupuncture for 117 conditions”

Summary of Findings of the Acupuncture Evidence Project

The following lists summarise the effectiveness of acupuncture for various conditions.

 

Table 1. Conditions with strong evidence supporting the effectiveness of acupuncture

Reviews with consistent statistically significant positive effects and where authors have recommended
the intervention. The quality of evidence is rated as moderate or high quality.
Allergic Rhinitis (perennial & seasonal)

– Knee osteoarthritis

– Chemotherapy-induced nausea and vomiting (with anti-emetics)

– Migraine prophylaxis

– Chronic low back pain

– Postoperative nausea & vomiting

– Headache (tension-type and chronic)

– Postoperative pain

Table 2. Conditions with moderate evidence supporting the effectiveness of acupuncture

Reviews reporting all individual RCTs or pooled effects across RCTs as positive, but the reviewers deeming the evidence insufficient to draw firm conclusions. The quality of evidence is rated as moderate or high quality.

Table 3. Conditions with weak positive/unclear evidence supporting the effectiveness of acupuncture

Reviews consisted mostly of weak positive evidence or conflicting evidence between reviews or between authors within a review, with reviewers summarising the evidence as inconclusive. Reviews are of low or very low quality; or there is conflicting levels of evidence within or between reviews.

Alzheimers disease – Acupuncture is Safe.

Cancer-related psychological symptoms – Strong evidence for safety.

From the painstaking work done by Stephen Janz and John McDonald in searching the evidenced based medical literature, we can now be confident that acupuncture is a safe and effective therapy for the conditions listed above.  As more research is done, the list of these conditions and the efficay of acupuncture will be modified.
