Acupuncture 'like migraine pill'
Acupuncture - real or sham - is as good as medication for
preventing migraine, a study has suggested.
BBC Online
March 2006
German researchers treated almost 900 patients with either standard drugs,
traditional Chinese acupuncture or "fake" acupuncture.
Virtually the same proportion of people in each group found the number of
days affected by migraine was halved.
The UK's Migraine Association said the Lancet Neurology study showed there
was no "one-size-fits-all" treatment.
'Effectiveness key'
Migraine affects up to 15% of the UK population - around two thirds of
sufferers are women.
An attack can last up to 72 hours, and sufferers experience an average of 13
attacks a year.
The results come from acupuncture trials in Germany, where the treatment is
commonly used to treat migraine.
The people in the study were given two sessions of either traditional
Chinese acupuncture or a "sham" version - where needles were put into areas
of the skin not used in traditional practice.
A third group was given standard prophylactic treatment of either beta
blockers, calcium channel blockers or antiepileptic drugs.
They were treated over six weeks.
'Very interesting'
The researchers then returned to the patients between 23 and 26 weeks later
and checked on whether they had been "migraine free" for 50% of days.
It was found 47% of those receiving traditional acupuncture, 39% of those
given sham acupuncture and 40% of those in the drug treatment group had been
migraine-free for at least 50% of the time.
Writing in Lancet Neurology, the researchers led by Dr Hans Christoph Diener
of the University of Duisberg-Essen, said the results were surprising and
the mechanisms unknown.
They were therefore difficult to explain, he added.
He said: "Ultimately, one could argue that the efficacy of a treatment,
especially a treatment with almost no adverse events of contra-indications,
is more important than the knowledge of the mechanism of action of this
particular therapy.
"The decision whether acupuncture should be used in migraine prevention
remains with the treating physician."
Ann Turner, director of the UK Migraine Action Association, said: "This is
very interesting research.
"Migraine is such an individual and complex condition that not one treatment
will work for everyone."

Traditional Chinese acupuncture may have
no point, research finds
Acupuncture can halve the incidence of headaches among people
who are susceptible to them, scientists report today.
The Independent
29 July 2005
But it remains an open question whether traditional acupuncture arried out
according to the principles of the ancient Chinese practice is necessary.
Researchers found that sticking pins in randomly over the body so
they just penetrated the skin was equally effective.
Scientists in Germany who carried out one of the largest studies into the
alternative therapy found patients who received acupuncture had seven fewer
days with headaches over the four weeks following treatment.
Acupuncturists say there are 365 pressure points that must be stimulated for
the therapy to heal. These are said to tap into a dozen body energy
channels, or meridians. But patients who had the minimal acupuncture, with
randomly placed needles, had 6.6 fewer days with headaches following
treatment, an improvement almost equal to that for the traditional
acupuncture group.
Both groups received 12 sessions of the therapy over eight weeks. A third
group, who received no treatment, had 1.5 fewer days with headaches in the
four weeks following the trial.
There were 270 patients in the study in total who had reported suffering
tension headaches at least eight days a month.
Writing in the British Medical Journal, the researchers from the Centre for
Complementary Medicine Research at the University of Munich say the
effectiveness of the "minimal" acupuncture is "intriguing". Even though
fewer needles were used and they were inserted less deeply than in
traditional acupuncture, their physiological effect cannot be considered
"completely inert". Alternatively, the therapy may have produced a placebo
effect more
potent than that associated with drugs, they suggest.
The study is the latest to suggest that "minimal" or "sham" acupuncture is
as good as the real thing. A study last year of 302 mostly female migraine
patients found both methods were equally effective in reducing attacks.
An earlier study, published in the BMJ last year, also found evidence for
the effectiveness of acupuncture as a treatment for headaches and migraines.
A trial organised by the Royal London Homeopathic hospital involving 400
patients with frequent head-aches found their headaches sharply reduced
after 12 sessions of acupuncture.
The patients were mainly women who had been taking three or four paracetamol
a day, on average, before the study. A year later, having had 12 acupuncture
sessions, they had fewer headaches, made fewer visits to the GP, used less
medication and took less time off sick.
But sceptics remain. At least 26 randomised controlled trials had previously
been published showing no convincing effect of acupuncture on headaches.

Fake acupuncture 'aids migraines'
Fake acupuncture works just as well as the real thing in
relieving migraines, scientists have found.
03/05/2005
In a study of more than 300 patients, both genuine and sham acupuncture
reduced the intensity of headache compared with no treatment at all.
But real acupuncture was no better than needles placed at non-acupuncture
points on the body, the Journal of the American Medical Association reports.
It goes against recent research showing acupuncture works in its own right.
Placebo effect
It has long been debated whether acupuncture works in a unique way or
whether any benefits gained are merely down to a person's expectation that
the treatment will work.
The latter is called the placebo effect.
To investigate this, Dr Klaus Linde and colleagues randomly assigned 302
people with migraines to one of three groups.
One group received 12 sessions of genuine acupuncture over eight weeks.
Another group received 12 similar sessions of acupuncture, except the
needles administered were not placed in parts of the body thought to relieve
migraine pain, hence any benefit would likely be placebo rather than real,
according to the researchers.
The third group received no treatment but were placed on a waiting list to
see a migraine doctor.
Less pain
All of the patients kept diaries about their migraine symptoms.
While the patients on the waiting list continued to have headaches just as
often, the ones who received acupuncture - sham or real - had fewer
headaches.
The average number of days blighted by a headache went down from about five
to two.
This may be due to "non-specific physiological effects of needling, to a
powerful placebo effect or a combination of both", said the researchers.
But Dr George Lewith, who recently published work suggesting acupuncture
has an effect above and beyond placebo, said although the present study was
well conducted, it did not truly test the placebo effect.
"We do not know whether this sham acupuncture is active or not. To test
for placebo effect you have to use an intervention that only raises a
patient's expectations.
"The authors note themselves that something else could have been going on
as well."
The British Acupuncture Council said that using pre-prescribed
acupuncture points for all patients might have skewed the results.
"Acupuncture treatment is different for each person. The formulaic
treatment part of the study would be inappropriate for some patients. This
would reduce the apparent effectiveness in the acupuncture group."
The council said there was good evidence to suggest acupuncture was
helpful for treating migraine.
Ann Turner of the Migraine Action Association said: "Acupuncture may be a
good treatment option for migraine sufferers to explore."
More than one-in-10 people in the UK experience migraines, two-thirds of
whom are women.

Acupuncture 'more than a placebo'
Scientists say they have proof that acupuncture works in its
own right.
BBC News 30 April 2005
Sceptics have said that any benefits gained from acupuncture are merely down
to a person's expectation that the treatment will work.
But researchers at University College London and Southampton University say
they have separated out this placebo effect.
Their findings, based on a series of experiments and brain scan results, are
published in the journal NeuroImage.
Dummy treatment
The researchers used positron emission tomography (PET) scans to see what
was happening in the brains of people having acupuncture treatment for
arthritis pain.
Each of the 14 volunteers underwent each of three interventions in a random
order.
In one intervention, patients were touched with blunt needles but were aware
that the needle would not pierce the skin and that it did not have any
therapeutic value.
Another intervention involved treatment with specially developed "trick"
needles that give the impression that the skin was being penetrated even
though the needles never actually pierced the skin.
The needles worked like stage daggers, with the tip disappearing into the
body of the needle when pressure is applied. This was designed to make the
patients believed that the treatment was real.
The third intervention was real acupuncture.
Brain activity
When the researchers analysed the patients' PET scan results they found
marked differences between the three interventions.
Only the brain areas associated with the sensation of touch were activated
when the volunteers were touched with the blunt needles.
During the trick needle treatment, an area of the brain associated with the
production of natural opiates - substances that act in a non-specific way to
relieve pain - were activated.
This same area was activated with the real acupuncture but, in addition,
another region of the brain, the insular, was excited by the treatment.
This was a pathway known to be associated with acupuncture treatment and
thought to be involved in pain modulation.
Sarah Williams of the British Acupuncture Council said: "This is very
positive news for acupuncture and this latest research is an exciting
illustration of what acupuncturists have known for a long time - that
acupuncture works and its effectiveness goes beyond the placebo effect."
Professor Henry McQuay, professor of pain relief at the University of Oxford
and member of the Bandolier group that looks at the evidence behind
different medical treatments, said: "The great bulk of the randomised
controlled trials to date do not provide convincing evidence of pain relief
over placebo.
"Some people do report that acupuncture makes them feel better.
"But it is extremely difficult, technically, to study acupuncture and tease
out the placebo effect."
