PainRelief.com: What is the
background for this study?
Response: The burden of migraine is
substantial, resulting in considerable economic and social losses. The latest
Global Burden of Disease Study showed that 1.25 billion people had migraine in
2017. A significant number of patients are still not responding well to drug
therapy, or cannot tolerate the adverse effects of drugs, or have
contraindications, which can lead to low medication compliance, headache
chronification and acute medication overuse. Prophylactic drugs should be
recommended for migraineurs who have at least four headache days per month, but
only 13% of patients reported current use of preventive drugs. Besides,
ineffectiveness of and/or contraindications to migraine medication affect
10-15% of people with migraine. Hence, a need exists to investigate non-drug
interventions.
Previous studies suggest that
acupuncture works particularly well on a range of pain disorders. However,
clinical evidence for the benefit of manual acupuncture for migraine
prophylaxis remains scarce. Appropriate placebo control settings and successful
blinding are two critical elements in addressing this challenge. Sham
acupuncture involving penetrating needles should be avoided in clinical trials.
Previous acupuncture research has often used penetrating sham acupuncture,
involving needling non-acupuncture points, needling irrelevant acupuncture
points, or superficial needling. However, whether the needle is inserted into
an acupuncture point or a non-acupuncture point, it could produce a
physiological effect. Comparisons between true acupuncture and sham acupuncture
might also be biased by unsuccessful blinding. To ensure an inert placebo
control and successful blinding, we recruited acupuncture-naive patients, using
non-penetrating sham acupuncture at heterosegmental non-acupuncture points as
the control, and designed the same procedures to perform the same rituals as
much as possible in the manual and sham acupuncture groups.
