The Annals of Internal Medicine (of
all places) published the results of a survey of 232
people who had arthritis and were under a rheumatologists
care. Of those 63% responded to the survey by saying
they were using some form of "complementary care" as named by the study. Of those people 31% were using
chiropractic. These number may themselves be grossly
under reported as only 45% of the patients told their
doctor about using the other forms of care.
These reported numbers translate to over 19% of the
public who is seeing a rheumatologists is also seeing
a chiropractor. And if less that half of the patients
are telling their doctor about it the actual number
may be twice as high.
Possibly the most impressive statistic was that 73%
of those trying chiropractic found it helpful. The
reasons given why people said they tried the non-medical
care was to control pain, because they heard it helps,
because it is safe, because it helped someone they
know, and because their prescription medication wasn't
working.
