I agree with what has been said. I also find I learn alot when the patient returns. This helps me give better physio to our whole community.
So I might say to a patient " I'm pretty sure you are going to find a big difference from this treatment, but I'd like to see you come back at least once more. That way, If I'm right, and you are doing super, I know that this is a treatment to do on others. But if there are problems with it, I know NOT to do the treatment this way in the future. I only learn how to be the best physio if I know my treatments worked out." If you absolutely don't need any treatment after today, you can always call with one day notice and tell the receptionist you are fine, cancelling next weeks appointment, at no cost to you."
People in our city realize that if their physio never gets to find out how her patients are doing after the fact, she's not going to be the community resource she could be.
