Hi,
interesting, isn't it. There are so many areas Physios can work in, that the decision about where to go to next is difficult to make. Manual Therapy is never wrong, neither is Neurology - they both offer knowledge that is transferrable into other areas. And often, the Masters programme leaves you options to mix topics, e.g. you can chose a neuro rehab paper within your Master of Musculoskeletal Physio.
I don't know any country that offers cheap living AND good quality tertiary education.
Please don't forget to think about the country that you would llike to end up working in, as you need to check that whatever Master's degree you do is accepted in that country.
By the way, you talk about DPT - does that mean Diploma?
Master's degrees are based on a Bachelor's degree - do you have a Bachelor in Physio?
Good luck,
Fyzzio
