Let me ask you an honest question foughtfryer.
Do you think MD's know more than DC's on such topics as spinal biomechanics, spinal pathology, and pain? I doubt it. MD's are very well trained and i am NOT saying med school is bad because it's far from that. I'm just saying that i don't think you're giving DC's enough credit. They still do 4 years of school ( all be it, no residency). I feel DC's are well equiped to do their job as CHIROPRACTORS because i have both med school and chiro school friends and both are submersed in their studies. They even use the same anatomy, biochemistry, and pathology text books.
They may use the same texts but if they then "learn" that the books are wrong and that subluxations are the cause of all illness, what book is on the shelf really doesn't matter.
And chiropractic school is three years not four.
And yes, I am saying that "MD's know more than DC's on such topics as spinal biomechanics, spinal pathology, and pain" and so do some chiropractors! (see below)

One of my friends is an M1 at the University of Toronto and the other friend is a first year at the CMCC (Canadain Memorial Chiropractic College) and they study together regularly.
I know that's not scientific evidence or anything like that, but it's just something to think about!
Take care
So lets see the scientific evidence (largely a repost - but it goes to Jesse's question):

Assessment of knowledge of primary care activities in a sample of medical and chiropractic students.

OBJECTIVE: To examine the influence of chiropractic education on knowledge of primary care tasks. Scores received on a test of knowledge of primary care tasks were compared between 3 samples of chiropractic students and 1 small sample of medical students. DATA SOURCES: The taxonomy of primary care tasks that was previously published provided the basis for test items used in this study. A team of test writers prepared an evaluation instrument that was administered to final-term chiropractic students at 3 colleges and to a small sample of medical students as they were entering their residency programs. RESULTS: The chiropractic students scored below the medical students on the primary care examination in every area except musculoskeletal conditions. Chiropractic students scored higher than medical students on the musculoskeletal portion of the examination. CONCLUSIONS: In this sample, chiropractic students performed almost as well as medical students on a test that was designed to measure knowledge of primary care tasks. If the premise is accepted that medical school is the gold standard of primary care instruction, that chiropractic students fared almost as well as medical students is noteworthy.

So, what they did was give a test to on basic primary care to three groups of chiropractic students in their final terms in chiropractic college (groups 1, 2 and 3) and one group of recent medical school graduates who had yet to start residency. The test was created by "2 DCs who also hold bachelor's degrees, 1 DC with a diplomate in radiology, a DC enrolled in the final year of a radiology residency program, and 2 MDs". It was a 100 question test broken into two 50 question sections and some description of attempts to validate the instrument for use on chiropractic students is offered by the authors. So here is what they found...
Group 1: 21 students, raw scores 32.7, % scores 65.4, SD 4.6
Group 2: 22 students, raw scores 28, % scores 56, SD 5
Group 3: 79 students, raw scores 32.1, % scores 64.2, SD 4.4
Groups 1 to 3 (combined): 122 students, raw scores 31.4, % scores 62.8, SD 4.7
Group 4: 20 students, raw scores 36.7, % scores 73.4, SD 3.3
Now, while the medical student sample size is low, the
performance of the chiropractic students is abyssmally low. 68% of all of the chiropractic students (who are very soon to enter practice) taking the test, a test designed and validated by DCs, scored between 58.1% and 67.5%?!? This is noteworthy? Yes, it is! It succinctly proves the point that DCs are very ill prepared to serve as primary care physicians. As for the medical students, 68% scored between 70.1% and 76.7%. While I would normally bristle at these data as the sample size is so small, it should be noted that the SD was the narrowest, by a considerable amount, in this group. This leads me to question the need to validate the instrument not only with chiropractic students (as was done) but also with medical students (not done in this study). These results seem to indicate a very tight "clumping" of scores in the medical student group, which may suggest that areas of the test represented material outside their scope of instruction.
Other results:
Percentage scores of all students on 5 major categories of primary care tasks
Primary care activities (% correct)
Information gathering Group 1 - 60.12, 2 - 57.04, 3 - 64.72, 4 - 76.64
Screening and prevention Group 1 - 35.72, 2 - 27.09, 3 - 38.93, 4 - 63.10
Other diagnostic procedures Group 1 - 66.94, 2 - 57.64, 3 - 65.83, 4 - 74.34
Counseling and education Group 1 - 69.05, 2 - 75.00, 3 - 87.74, 4 - 95.24
Management of acute/chronic conditions Group 1 - 65.71, 2 - 57.04, 3 - 64.69, 4 - 73.01
By these data, chiropractic does not perform information gathering or screening and prevention well at all.
I'm not going to post the data on all individual "subcategories of management of acute and chronic conditions". Suffice it to say that group four handily out performed all of the other groups in every area except one:
Musculoskeletal (% correct) Group 1 - 71.04, 2 - 56.95, 3 - 54.75, 4 - 48.02
(but group four did outperform the others in neuro!:
Neurological (% correct) Group 1 - 78.1, 2 - 61.67, 3 - 78.99, 4 - 82.86)
My most significant concern on their methodology is this - the test was given to medical students about to enter residency training and to final term chiropractic students about to enter practice (presumably). Now, the article acknowledges a gap, but that gap
should only
grow as the medical students have at least three years of training remaining. Also, no attempt was made to identify what area of medicine the MD students were entering. I would argue that given the latitude to self direct fourth year cirricula to a certain degree, students heading into primary care would likely outperform a random sample from all medical students on this examination as they would have more training in this area than the "average" medical student.
Lastly, the conclusions do not match the data. It is not "noteworthy", in a positive sense, that chiropractic students about to enter the workforce score abyssmally low on a test of basic primary care skills. Comparing them to MD graduates with at least three years of training remaining is comparing apples and oranges. And even given the disparity in time remaining in training, the MD students quite significantly outperformed the chiropractors. This paper completely demonstrates what I have been saying since I started coming to this forum. Chiropractors are not equipped to act as primary care physicians.
