I too feel this is a little silly a question. Are they really asking it. Neither is more important, they are BOTH essential. That is the first answer and is part of the roles and responsibilities of you as a PT. More than that if you don't do the former you might find yourself going the way of several others and ending up banned from the PT register with the HPC.

Notes are fundemental to the treatment of the client. They set up the path to a good initial treatment plan, document the results of that treatment and highlight the progression. More than that they lead the way for someone else who might find themselves treating your patient when you are not there. They are also a medicolegal requirement.

So a bit of a silly question. But maybe if they are asking it the answer is that they are synonymous i.e. note taking is part of the treatment.
