And I'm glad you understood the joke 😉
I mean I think it is a very valid point and one that isn't always taken seriously. You used to be able to do an internship essentially and become a Certified Athletic Trainer. You also used to be a PT with just a Bachelors Degree. Both professions have evolved and progressed and those things aren't available anymore. Yes, if you are an AT who went with the internship route or you are a PT with only a Bachelors, you are able to work, but you can no longer qualify in that manner anymore.
Athletic Training and Physical Therapy share many things. We both are able to do rehabilitation and functional progression, etc. We both do orthopedic evaluations. But while the athletic trainers stick to the more athletic population and are able to handle more emergent situations, physical therapists stick to the clinic and work more with a large variety of patients.
It is my opinion that both professions are very valuable to healthcare in general and need to work better together. It is likely that won't happen, but I would love to see it! Individual professionals work together all the time, but the two national professional organizations will probably never work together which is unfortunate.
