Topics Physical therapy: Treatments with Elements

Did I say unusual?

The physical therapy involves two kinds of treatment, that's what I'm going to expose in my presentation.
I'm going to present topics like:
· General threatments in the practice
·Diferences manual treatments with natural treatments
·Whater, Electricity,and heat

I choose this topic cause people use to think the phisical tratmens are just involved with muscles and mechanical works, but the reality is that the work with a pacient is not just to move legs and arms, there are many forms of treat, and when the people is trated with them they say "OH!? what's the utility of this? I think is useless".
So I want to expose that, at least for my english class know.
