Treating patient needs.

Whilst being on the musculo-outpatients prac, I recently had an on-going patient return after a few months of not attending physio. Whilst looking through his previous notes, I found he had attended physio for all different problems, the last visit was regarding his low back pain.
On subjective, I found out the only reason he returned was because he wanted to have his exercises reviewed and progressed. This was an 84 year old man, who liked too keep very fit and active. He reported no pain, or any other concerns affecting his everyday activities. So I though that this was a pretty straight fwd and easy case, I just had to go through his exercises, make sure he was doing it correctly and modify it.
So I did a brief objective, quickly screening all the joints/ rom etc. Some of the main findings were he had about 5-10degrees reduced PFlxn and Inversion on his (L) ankle, excess pronation L>R, and a length length discrepancy with the (R) being 2 cm longer. However none of this were his problems, so I didn’t take that into consideration, in my mind I was there to sort out his exercise program. Of course all this had to be reported to the superviser, she then came into the room to further assess his ankle. So ½ hr later there I was treating his ankle, trying to improve 5-10 degrees of Pflxn and Inversion. So at the end of the session I achieved full and equal range at both ankles, provided him with ankle ROM ex, taping, and advised him on the need for orthotics.
Normally I’d think that was a successful treatment session, however in this case, I felt the needs of the patient weren’t being addressed. The patient came in just wanting his exercises reviewed, instead he’s got his ankles treated, which weren’t causing him any pain or referred problems. I just felt the superviser overtook the session, and directed it away from the needs of the patient.
My concern is that at the end of the day, the patient didn’t get what he wanted, he was due for a review session for the following week, where is modified exercise program would have been prepared and ready to go, unfortunately he didn’t attend the following week.
So my question is, should I have just been concerned about what the patient wanted, or should I have let assessment guide treatment..
