"We also have far fewer snake-oil salesmen ripping people off for cures"

Yet we still have chiropractors and homeopathy.

Hold on - Chiropractors are in the same class as homeopathy? I thought Chiropractors (which, admittedly, I've never been to, but have heard many good things about - particularly when people need to get their back "adjusted") were in the same class as Acupuncturists - kind of easternish philosophy, but effective within their domain. Not so much focussed on increasing health, as enhancing comfort (or reducing pain) without drugs.

Not the case?

I would like to know the real answer on this, too. I have read from people who claim to have been on the industry's inside (went to school for it, etc). The claim is that there are a bunch of logical steps based on false premises/beliefs and that some of the work results in mid- to long-term damage to the body in exchange for short-term relief.

Edit: http://www.chirobase.org/05RB/CPSQ/02.html -- More information that looks like something I have read.

Edit2: http://www.chirobase.org/01General/controversy.html -- "NACM members publicly renounce the subluxation theory and other forms of chiropractic pseudomedicine." Interesting stuff. What I read: There is a portion of "chiropractic medicine" that is snake oil; how do I identify what is real? Are NACM members better informed?

I've been to a chiropractor before and it really does work, at least for the problem I was experiencing (which was some sort of simple alignment problem.) The guy basically just pushed on my spinal column in different directions and I could clearly feel things moving back into place. I definitely would not lump them in with the quackery that is homeopathy, as long as you stay within the bounds of "pushing bones into alignment" and stay away from things like "improve the chi flow throughout your chakra nodes" or some such nonsense.

Until you realize that your bones were 'out of alignment' because you have weak core muscles that you should build up instead. In fact, 'pushing spinal column bones into alignment' without any x-rays or further inspection sounds pretty dangerous to me. What if the chiropractor pushes it too far and strains something, causing me to return for another adjustment? Everyone I know who has tried a chiropractor ends up going back over and over again, like an addiction.

Meanwhile, I had some back pain and started doing pilates and it evaporated, because now my core can actually hold my backbone up.

/plural of anecdote is not data

I've seen a chiropractor and x-rays are a part of the procedure. You can't do medicine without seeing that there is a problem, correcting the problem, and then verifying that the problem is solved.

No one is debating that. What we're debating is whether chiropractic is medicine.

If chiropracty works, it would be a surprise given the history. See http://en.wikipedia.org/wiki/Chiropractic_history for more details, but basically it was founded by a complete crackpot and there's no reason to believe it should work.

Further, many studies have found weak effects, no effects, and negative effects. When you see this kind of evidential pattern, it almost always means that the effect isn't real and we're just seeing experimental error. See http://en.wikipedia.org/wiki/Chiropractic#Evidential_basis

That said, the placebo effect for something like chiropracty or massage can be very strong - and the placebo effect is real! Giving someone a saline shot creates a stronger effect than giving them a sugar pill; I don't know where chiropracty exists on that spectrum.

Off topic -- Where is the 'Edit' button on http://en.wikipedia.org/wiki/Chiropractic#Evidential_basis ?

The article doesn't say it's locked, but I see no edit button.

I was trying to replace "Opinions differ as to the efficacy of chiropractic treatment" with "Opinions differ as to the ability of chiropractic treatment to produce an effect", because I have a grudge against overly complicated language.

What's already there is better. :(

Also, if you look to the top right corner of the page, there's a lock icon that shows the article is semi-protected. You can't edit it without logging in.

Why is replacing one word with 4 making it less complicated?

Because more people will understand the longer version than the shorter one. A wiki is not a computer program.

My own anecdotal experience would leave me surprised if controlled studies found that modern chiropractic care had no useful effect at all. Over a three month period I watched one guy go from a hunch-backed nerdy appearance to a shoulders-back, upright, and confident posture. Chiropractors probably can't cure ulcers, but they probably can accelerate improvements in posture, which have payoffs in other areas (improved posture->reduced pain->less stress caused by pain->better quality of life).

PBS did a report on alternative medicine, including Chiropractic. They didn't have much good to say:

I agree they are in the same class with acupuncturists, in the "stuff that doesn't work"-class.

Actually the best current evidence is that acupuncture does bring real pain relief: http://www.umm.edu/news/releases/back_pain.htm

That said, most of its relieving effect is due to the placebo effect, and there is no evidence saying that it can do anything for you other than possibly reduce pain.

"The sham acupuncture studies were double-blinded, meaning neither the researchers nor the participants knew who was receiving the real or the sham treatment. When looking at those studies, the reviewers found the differences in pain ratings showed a significant difference between the real acupuncture and the sham acupuncture groups, indicating that the benefit was not just due to the placebo effect."

How did you get "most of its relieving effect is due to the placebo effect" from the article?

I concluded that from several articles that I read on the way to picking that was as best representing current thought on the effectiveness of acupuncture.

There is still debate on whether real or fake acupuncture is better. (Studies have come down on both sides of this issue.) However pretty much everyone who has tried to study the subject has found that both real and fake acupuncture have a definite impact on pain. Frequently both will outperform conventional medicine. For a random example see http://featuresblogs.chicagotribune.com/features_julieshealt....

From that I know that there is a readily measurable benefit to acupuncture, another readily measurable benefit to the placebo, and the difference between the two benefits is difficult to measure. Which leads me to conclude that most of the benefit from acupuncture is due to the placebo effect, and only (possibly) a little is because acupuncture itself is effective.

Sadly, they get around all the regulation by not making specific medical claims. If they did, then regulation would come down on them like a ton of bricks (as it did to producers of Cherries at one point). It's the difference between saying "Product X will cure Y" (illegal unless it's gone through all the testing) and "Product X may promote health" (which is entirely legal). It doesn't make much sense.

Two weeks ago I went to see a chiropractor. I was in so much pain I could barely walk, and my lower back wouldn't flex enough for me to stand up straight. She thought I probably had a pulled muscle. She stretched my legs and hips, twisted my spine a bit and showed me some stretches that I could do at home. I left feeling a bit sore, but otherwise fine. It took 20 minutes and cost me $60.

It might not be medicine, but it's not snake-oil either.
