I need help

I am doing a project in my Exercise Science class on Athletic Therapists.
I would like to know if there is any info. that you could give me on the profession.
I also have to do a prsentation, I wanted to do taping.
I already know how to tape a shoulder after an AC joint separation( as I have experienced one myself).
I was wondering is there any way I could get instuctions on how to tape a wrist or ankle, for demonstation purposes. I would also like to know why the tape job is done the ay it i, besides for support reasons.
I know this is alot to ask, but it would be a big help if I could get any info.ThanksHuw Phillips
