Physical therapists are more helpful than doctors for many maybe most problems, in my experience, though the variation in quality may be greater. Part of this could be economics; pt’s have more time. In the future I think having pt rather than doctors as primary point of contact for most patients will be shown to result in better outcomes. I susspect the reason this isn’t already the way it works is mostly because of organized labor (the ama wouldn’t have it) and liability.
