That's what we found. This was based on the recall of the patient about care they had, weeks to perhaps many months previously. In our cohort study, our second study, we're going to have satisfaction data much closer to the time of care. This basically replicated some of the work Dan Cherkin had done on the West Coast which showed that patient satisfaction was somewhat greater with chiropractic care. The improved satisfaction may be due to factors other than improved functional status, because satisfaction is a complex issue and functional status is only one of the components of patient satisfaction.
Chiropractors are clearly mainstream participants in back pain care.
The optimal role of chiropractic and spinal manipulation is still evolving. We need to continue current research programs, not necessarily my own, but also those that are going on in the other parts of the United States to determine optimal types of spinal manipulation. The role of adjunctive therapies in back pain is very unclear and this relates to chiropractic and physical therapies. The adjunctive therapies had substantial overlap between those two groups. Many of those therapies have not been well-tested.
