You just started a thread a few days ago asking for people to list current issues facing physical therapy. Stop expecting others to do your homework for you. If you can't come up with some ideas and put together an informed opinion with all the resources that are out there, you should not be applying to PT school.
Not only has this question been answered multiple times on this forum alone, as I pointed out in your prior thread, but you also have the entire internet at your disposal. Stop expecting people to spoon feed you.
If you have specific, thoughtful questions about an issue relating to PT that you have researched and are having a hard time understanding, that is the time to come here and ask questions about it. The membership of SDN will then be more than happy to help you learn. If you are curious about the opinions of people in the PT community on a particular topic of interest, ask away. SDN users are always willing to contribute an opinion.
Learning about the things effecting the physical therapy profession is not a one time box for you to check in your application process, so that you can have some cookie cutter answers to give in an interview or an essay. It is something you should have been doing all along, over the course of an extended period of time, because you care about and are seriously interested in the profession of physical therapy and its future.
Please don't think I'm trying to be nasty to you. I'm just trying to hit you with a little reality.
