Ihave been meaning to blog on the results of a Lancet article finding neither spinal manipulation or NSAIDs are effective on low back pain. However, Eric from NPAThinktank beat me to it with a post on Evidence in Motion's blog. It is very well done and thought out.
The key point we must all understand, is that the population tested was a heterogeneous group of low back pain sufferers. Despite the mounting evidence, no sub-grouping of patient's was done. Predictably, then, to significant results were found. I don't care how many low back pain studies are done, if no treatment based classification is used, you will not find significant results.
Eric quotes Dr. K. Shepard using a great analogy for this. I post it here for your convenience:
A study that randomly assigns patients with low back pain to various conservative treatment protocols will produce the same results as a study that randomly assigns patients with abdominal pain to undergo appendectomy, cholecystectomy, or exploratory laparotomy. Neither study makes any sense.
Our hope in the rehab world is that the referral sources also have the great evidence of treatment based classification and the dramatic effects of lumbar manipulation on the right sub group of low back pain patients. Please read Eric's great post.
