Here is even a better site:
www.chirobase.org - I urge you to take a close look at this site.
Chiropractics is based on subluxations. Go do some research on it. The whole profession is based on junk science. Chiropractic schools teach fundamental science that is wrong. You cant treat for something that doesn’t exist.
Someone may feel better after any type of placebo treatment, doesn't mean it was actually effective. I think that whatever they do that is helpful can also be done by a physical therapist and at least a physical therapist won't give you a stroke. The is a reason almost the entire medical profession (real doctors) look down on chiropractics (possibly because the people who practice traditional, evidence-based medicine don't like when non-traditional medicine takes their patients and hurts them more).
I think it boils down to a profession that should have been discarded in the 19th century. It's witch doctoring. You can't go this long without having any evidence supporting your profession. All the evidence is contrary. It doesn't work, they can't prove it works, it's fraud.
All I can say is that its efficacy hasn't been proven through clinical trials. The evidence for chiropractic is very bare.
With that said, do I think chiropractics has its place? Of course, much like Chinese medicine and acupuncture. It may 'work' for some, but I think I will stick to traditional proven medicine.
And yes, I have been to many chiropractors.
