F.:
You need to talk to a local PT and find out what their requirements are - call your state employment office and find out what is needed as well.
Being a Physical Therapist is hard work. The schooling required is long and hard...you need to know anatomy and physiology REALLY good. Sports medicine...etc. you can check out going to massage therapist school - it's a trade school- you might qualify for a grant - I don't know. but you can start there...
they will most likely teach you how to use the TENS unit, heat, ice, etc. and how joints work, etc.
Good luck!~
