I am an occupational therapist in a skilled nursing facility. Recently I had a customer who had undergone a knee replacement and presumably needed some therapy prior to going back home. That's a main reason why people come to our facility, anyway.
During my evaluation, he insisted that he didn't need any help performing his usual daily routine, and that he just needed physical therapy for his knee. Sometimes that's true, so I didn't push the issue. When I went to leave, he asked me if I would help him get out of bed and get to the bathroom.
I helped him and completed my evaluation, determining that he did in fact need therapy. I worked with him for a few days before he ultimately refused to do anything with me.
I was actually very relieved, as he was very high maintenance mentally.
