Study reveals health benefits
of ancient healing art

Judith Ritchie slowly eases a fine steel needle into the back of her patient at
a point marked out in felt-tip ink. As the needle is gently tapped, Judith
explains: 'This point lies over the organ I want to strengthen, her liver. I
want to improve the quality of her blood and her yin, which affects the energy
balance.'
Acupuncture relies on a different language and different tools
from Western medicine, but however strange it seems at first, this patient,
Louise Shelver, is a convert. For years she has had debilitating migraines and
pre-menstrual tension.
'The
doctor told me that I could go on the Pill or have anti-depressants,' said
Shelver, from Reading, Berkshire, who is treated fortnightly. 'I didn't want
that, so I came here and it has totally altered my life.
'The migraines come maybe every three months now, but they are
not so bad and I feel like a different person. My husband has noticed a huge
change because I don't get so low. Some days I feel on top of the world.'
Controversy has raged for years over whether acupuncture has
only a placebo effect that makes people feel psychologically and physically
better but changes nothing physiologically.
However, this weekend a new study reveals for the first time
that it provokes a specific response in the brain, shedding light on how it
might affect the body's pain pathways. This helps to explain why both patients
and health professionals trained in Western medicine are increasingly turning to
this ancient form of Chinese healing.
Ritchie is a qualified children's nurse who has spent the last
nine months learning this complementary therapy.
'I began to realise acupuncture's use goes far beyond pain
relief. In the West you treat a disease. With acupuncture you're treating the
whole person - the root of the problems, not just the symptoms.
'I can spend an hour or more with a patient. In the NHS you
never get that time. Acupuncture can benefit so many adults and children.'
More than two million treatments will be given this year. Most
practitioners work in private clinics, charging around £30 a time.
Increasingly, however, acupuncture is becoming mainstream, and
it is being offered in the NHS because of patient demand. The profession is
heading towards self-regulation on the recommendation of a House of Lords
committee. This will protect patients more by preventing just anyone calling
themselves acupuncturists.
The latest study is from researchers at Southampton University
and University College London, who devised a clever trial to determine whether
acupuncture worked by carrying out brain scans on patients receiving it.
The patients, all with painful osteoarthritis in their thumbs,
were divided into three groups. The first group were touched by blunt needles
which did not pierce the skin and had no therapeutic value.
The second had 'sham acupuncture' they believed was real. Their
scans showed that one area of the brain associated with the production of
natural opiates lit up.
In the third group, who received real acupuncture, the scans
showed that, as well as the opiate centre, another region of the brain, the
ipsilateral insular, was activated. This region appears to be involved in pain
modulation.
Dr George Lewith, a research team member from Southampton, said:
'This shows us that real acupuncture produces a demonstrable physiological
effect over and above a simple skin prick.
'We still don't fully understand how pain works, but we do know
that after patients receive acupuncture there are changes in the way they manage
their problems that last for up to two years.'
Acupuncturists believe there are 12 energy pathways in the body,
each associated with a different organ, and the treatment re-establishes the
energy balance in organs when it goes awry.
To treat an illness, practitioners take a full view of the
patient, asking how their body functions, about their character and even their
childhood. Treatment is varied accordingly. Fine needles are inserted into
different points, either to stimulate or reduce the flow of energy along
pathways.
It is said to work for an increasing number of conditions. Its
worth for depression, migraines, chronic pain, rheumatism, eczema, multiple
sclerosis and high blood pressure has been subjected to clinical studies. Yet a
growing number of patients have it simply because they say that acupuncture
makes them feel happier and more fulfilled.
The patients' profile is also changing. Gwyneth Paltrow and
Cherie Blair are at the celebrity end of the scale, but such patients as retired
firefighter John Thurston show how widespread acceptance of the therapy has
become.
Thurston, at 79, is one of the oldest patients at the College of
Integrated Chinese Medicine in Reading, Berkshire, where he has been treated
fortnightly for several months.
A stroke last year left him with difficulty in walking, numbness
in one hand and unable to lift one of his arms. 'It has made a remarkable
difference,' said a delighted Thurston. 'I can dress myself now, whereas after
the stroke I couldn't do a button up. I used to find it hard to lift my left leg
up and I'm now walking more or less straight. I have got a lot more movement
back.
'When the doctors signed me off at the hospital, they said
cheerio and that was it. I did have a a bit of physiotherapy, but it's coming
here that has really helped. I wish everyone could have it. It's done me a world
of good.'
Pinpoint prowess
Researchers in Sweden have found that acupuncture is effective
at relieving pelvic pain, a common complaint during pregnancy. Another clinical
trial at Stanford University in the US showed it could help alleviate depression
in pregnant women.
A study in the British Medical Journal showed that patients with
osteoarthritis in the knee who received acupuncture a well as an
anti-inflammatory painkiller suffered less pain and stiffness than those who
received the drug plus sham acupuncture, where the needle did not penetrate the
skin.
