Stimulating environments

Hi All,
This week I have been working with a patient who is very motivated in physiotherapy and works really hard for the whole 3 hour session. As a result, he is making noticeable gains in his balance leading to improvements in gait - which is his major goal. On Thursday, he came to Physio really agitated after a disagreement with the nursing staff and left after about 10 minutes because he was still really angry. We left him for 20 minutes and then my supervisor went and convinced him to return to Physio. I expected the session was going to be really ineffective due to his mood. But I was really surprised that he was able to do most of his exercises with a lot more control than usual. In reflection, I wonder whether perhaps this was because he had been stimulated by the disagreement which made his muscular activity more accessible. If so, I wonder if by making the patient’s environment in the hospital more stimulating we could get better treatment results. Has anyone had a similar experience with their patient’s?
