Zoe Yip asked the Naked Scientists:
I love your programme very much (http://www.thenakedscientists.com/HTML/podcasts/)! it's awesome!!!!
I was wondering how does the Chinese acupuncture work? Any scientific explanation on it?
Thanks a lot
x
What do you think?
-
The first question is does acupuncture work- or at least work any better than the placebo effect?
-
A while back I read that acupuncture is not as old as claimed. The oldest European mention is from a 1680s text. Europeans had brought back info on Chinese medicine beginning in the 1300s, but there is no mention of acupuncture until this 1680s text. A 2005 study published in JAMA showed that acupuncture and sham acupuncture had about the same success rate for relieving headaches.
-
There is Swedish research from 2009 on it suggesting that it doesn't seem to matter where you put those needles, around half of the patients treated will experience a pain lessening effect due to the treatment anyway.
They also used a special type of needles not penetrating the skin, but that seems to me to be of lesser importance, as there is a lot of other Chinese treatments using those 'special points' without penetrating the skin, acupressure, moxa, etc.
Still, if it is a 'sham' it works very well :)
As almost fifty percent found a relief in the treatment.
-
The last I heard (and I admittedly don't follow it well), there was some evidence that acupuncture did appear to work better than placebo for certain specific types of pain relief (though not as well as pharmaceuticals). Here's a link to the NIH (a US government agency) about it:
http://nccam.nih.gov/health/acupuncture/acupuncture-for-pain.htm
Although upon reading that again, they seem do be saying that although some studies showed that it appears to work, there isn't enough evidence yet.
-
wow that’s a really useful piece of information! thanks JP for the acupuncture website from the NCCIH!
actually i still believe that chinese acupuncture works only because of its psychological effects on patient, rather than its REAL “scientific” physiological effect on pain relieve. although being a chinese myself, i don’t really believe in the traditional chinese medicine at all haha!

yes haha! very true! playing around with psychology again!

Acupuncture is a form of placebo. For a fair assessment of it efficacy it would need to be tested on something that was measurable, something objective rather than subjective. Someone saying that it made them feel better should not carry any weight.

I've seen a film of chinese veterinarians setting a cow's broken leg, using acupuncture anesthesia, and there have been some clinical studies in the UK of the same process in human surgery.
I was recently recommended by a medical colleague to try acupuncture to relieve a chronic post-nasal drip, on the basis that it had worked for his wife. The immediate result (within hours) was a rapid drying of the 3-month-old drip, followed by a full-blown antibiotic-resistant sinus and respiratory infection - turns out that the drip was probably keeping the bugs at bay!
Conclusion: acupuncture can treat symptoms (pain, nasal drip...) but maybe not causes. Rationale: interrupting or overloading a neural feedback turns off the symptomatic response.

Anecdote<>evidence.
-
I think a film is evidence. And ultimately all evidence is just credible anecdote.
Very few people have ever observed an atomic bomb explosion but I'm sure you believe that E = mc2
-
"I've seen a film "
is an anecdote.
Also, I have seen a film of superman...
-
Have you ever seen an atom bomb explode? Can't imagine why the government spends a fortune on anecdotes.
-
You seem to have missed something.
Before they built the H bomb, there was a really good reason to expect it to work- it's part of the whole integrated web that is science.
One bloke saying "I saw a film" really isn't the same thing, is it?
You also seem to have missed the point about superman.
We know that you can fake stuff on films. How do you know the cow wasn't spaced out on morphine or whatever?
Even without subterfuge, the injury that caused the broken leg may have damaged the nerves to a point where the cow didn't feel a thing.
As you say, there are levels of evidence- starting from anecdotal.
If I say I prefer roast lamb to roast pork you probably won't question it.
If I say I prefer unicorn, you probably don't believe it.
Acupuncture is in unicorn territory.

...except for those who have experienced it.
We know very little about how fish decide to migrate or how birds navigate, but those who make their living from hunting and fishing know when and where to find their prey. AFAIK people have been poking each other and sticking pins in for a very long time, and there is significant agreement between acupuncturists as to what goes where, even if "what" and "where" mean as little to Joe Public as "neutron capture crosssection". As is clear from many of the posts in this forum, even well-educated amateurs have little grasp of quantum mechanics, but it works, so we use it.
So there's a mass of collated experimental data and a connecting hypothesis with, apparently, some predictive value. That's actually better than our current understanding of the surgical treatment of knee pain, and a lot less harmful than routine tonsillectomy or suspensory ligament correction.
There's an old adage "medicine is what we do to amuse the patient whilst nature takes its course". Whether acupuncture is in the realm of unicorns or chicken soup, it meets the primary Hippocratic criterion : "first, do no harm". And unlike surgery or radiotherapy, if it doesn't work, you can always try something else.

Why waste time talking to me?
Show that it's a real effect (rather than the placebo effect with a side order of confirmation bias).
Show that there's a plausible mechanism and real supporting evidence.
Win the Nobel prize, come back and laugh at me.
I really won't mind- The personal embarrassment I feel (very little- this is an anonymous web posting) will be much more than offset by the knowledge that the world has a new exciting field of effective medicine.
re.
"there is significant agreement between acupuncturists as to what goes where,"
You mean they all read the same book?
Wow!
There's the less old adage-
Q Do you know what we call alternative medicine that works?
A Medicine.
But even that';'s not the real problem: this is "it meets the primary Hippocratic criterion : "first, do no harm". "
One of the biggest risk factors for ill health is poverty.
Giving money to a snake oil salesman is very harmful.
It's even worse when they start to pretend that they can really cure stuff and thus dissuade people from finding effective (rather than fraudulent) treatment
In essence fraud is harm.

When you consider the low output of the Hiroshima bomb compared the amount of U235 used it makes you doubt E=MC^2
-
When you consider the actual mass loss in U235 fission, it makes you respect the prescience and precision of E = mc^2.
