Interestingly, I worked with the—I think it was—the Ontario Neurotrauma Foundation on an educational brochure to help parents and families go out and try to find resources, because a lot of people claim to have concussion services. They can help you get better and they list that.
My personal preference is research-based care, because there are a whole host of different things you can say you can provide, but I've just found in working with the staff at Holland Bloorview and their research team that the studies they do are real. They are working to improve every day on the information that gets out to parents and kids on how to get them back faster.
To summarize, research-based care has more value than just having a lot of clinics.
