It’s not because I treat a lot of them. It’s not because they pay my mortgage, or because they’re basically straightforward. It’s not even because they’re ‘nice’ to treat (as opposed to feet, for example).
It’s because they’re multi-factoral. Every one is different because every one is different.
This paper is worth a read.
I also like the fact that they make the distinction between physio being an ‘active’ therapy and chiropractic a ‘passive’ one. Maybe that’s why physio works.
