I n general, the harder a medical problem is to treat, the more treatment strategies exist. This observation is certainly true for migraine. Patients and physicians are constantly looking for alternatives to drug therapy, which is effective in the short term but may have severe unwanted effects in the long term.Nonpharmacologic treatments begin with common-sense advice, such as educating patients about headache and its management, identifying and managing triggers (e.g., keeping a headache diary) and modifying lifestyle. Some evidence exists for the benefit of behavioural treatment (e.g., relaxation, biofeedback, and cognitive-behavioural therapy).1 Riboflavin and coenzyme Q10 significantly decreased the frequency of migraine attacks, and the prophylactic efficacy of magnesium, particularly for children and migraines related to menstruation, has been substantiated.2 Alpha lipoic acid has not been shown to reduce the frequency of migraine, and there is no clear evidence to support or refute homeopathy.2 In general, most studies for these types of treatments are small and of low methodologic quality. This is no longer the case for acupuncture. A German randomized controlled trial (n = 302) showed that acupuncture is more effective than no acupuncture. Another German randomized controlled trial (n = 794) showed that 11 acupuncture treatments given within a six-week period was at least as effective as a β-blocker taken daily over a six-month period.3,4 As a consequence of these and 20 other high-quality trials involving 4419 participants, the 2009 Cochrane review by Linde and colleagues 5 found that there is consistent evidence that acupuncture is beneficial in the treatment of acute migraine attacks and that the available studies suggest that acupuncture is at least as effective as prophylactic drug treatment and has fewer adverse effects. Therefore, acupuncture should be considered an option for patients willing to undergo this treatment.
5Additional randomized control studies published since the 2009 review are in keeping with this conclusion. Yang and colleagues found that 24 acupuncture treatments, compared with topirmarate, were more effective and safe (11 times more patients experienced adverse effects in the topirmarate group than in the acupuncture group). Wang and coauthors reported that acupuncture was more effective than flunarizine in decreasing the duration of migraine attacks. 6,7 Acupuncture has also been shown to be more effective than standard therapy for the treatment of tension headache, osteoarthritis, shoulder pain and lower back pain, with fewer unwanted adverse effects.
8-12These clinically important results are accompanied by another finding that is common in acupuncture studies: there is no evidence of an additional effect of "true" acupuncture over "sham" acupuncture. 5 The current trial by Li and colleagues 13 did not find a significant difference between traditional Chinese and sham acupuncture in the number of days with a migraine during the study period, but a significant difference wa...
