Important to know: Chronic health conditions should be addressed under direct medical supervision of your GP or consultant, and acupuncture would be an adjunct or complement to usual care – we advise that you let you doctor know when you use this approach.
About the research: It is worth noting that in research, randomised controlled studies (RCT) are the most reliable in terms of quality of evidence, with a systematic review or meta analysis of numerous studies being the best way of seeing the overall picture of the state of the evidence. Below we have a selection of the available research, which does include some larger RCTs, and reviews of the literature alongside smaller studies. The n= figure tells you how many people were participants in the study.
Over 80 NHS publications since 2005 have recommended acupuncture both for tension headaches and migraine (and many more worldwide (Birch et al, 2018)
The British Acupuncture Council (BAcC) reviewed the evidence for acupuncture in migraine and tension headaches, where a large number of trials have been carried out, considerably more effective than placebo (Tavola et al, 1992.) The BAcC concluded there was some evidence that acupuncture has a significant therapeutic effect on symptoms such as pain and frequency in migraine attacks. It was also noted in a crossover research trial that in addition to demonstrating a significant effect in reduction of frequency of attacks and their duration, that acupuncture has a very low side effect profile (Hesse et al, 1994; Loh et al, 1984).
The British Acupuncture Council has a Research digest where they examined some recent studies on headache and migraine, as well as an evidence based factsheet (links are below).
Acupuncture has had a good profile for both migraine and tension headaches since the Cochrane review of 2009, which was updated in 2016 (Linde et al), including 22 trials (n=4985), finding evidence to suggest that adding acupuncture to symptomatic treatment of attacks reduces the frequency of headaches. The researchers expressed the need for further long term trials in this area.
The current NICE headache guidelines (2012; 1.3.9) state the following: “Prophylactic treatment: Consider a course of up to 10 sessions of acupuncture over 5 to 8 weeks for the prophylactic treatment of chronic tension‑type headache.”
A systematic review on migraine without aura (Xu et al, 2018) examined 14 RCTs (n=1155), drawing the conclusion that acupuncture is safe, more beneficial that sham control in addressing symptoms, although they were reserved in the strength of this finding by the quality of some of the evidence available, meaning further studies were warranted.
Ambrosie et el, (2012) looked at cost effectiveness of acupuncture use in this field, using the NHS measure of cost per quality adjusted life year (QALY) gain from treatment usage, finding acupuncture to be cost effective by this measure.
Mechanisms of action:
Acupuncture studies have shown it can: provide pain relief by stimulating nerves in body tissues and leading to endorphin release (natural painkilling substances), as well as downregulating the brain and nervous system’s reaction to stress and pain (Zhao 2008; Zijlstra et al, 2003; Pomeranz, 1987).
Acupuncture has been shown in animal models to promote the release of factors that involved in the reduction of inflammation (vascular and immunomodulatory factors – (Kim et al, 2008; Kavoussi and Ross, 2007 [review article]; Zijlstra et al, 2003), and also to affect levels of serotonin (in an animal model), and other peptides in the brain and nervous system and modulate blood flow in the brain and elsewhere in the body, in humans (Zhong and Li, 2007; Shi et al, 2010; Park, 2009).
