un-cooperative patient

Recently on a prac at ICU I had a patient who was post CABG and was awaiting a bed on the ward. There is a set clinical pathway for these patients which is followed quite stricktly. As there was no ward bed avaliable, the patient stayed five days in ICU instead of the norman one day.
I was assigned to this patient and went to speak to him about his rehab once his sedation had worn off. I thought I'd explain the pathway to him and as I did he seemed to become agitated. He interupted and said that there was no way that he was getting out of bed today or tomorrow or any day and that he needed rest.
I have had this problem before with patients, I'm sure we all have, but I've never found it this difficult to motivate one. Usually some positive encouragement and distraction did the trick. I realised the first thing I needed to do was educate him on why he needs to get out of bed and the benefit it would have on his health. He was a farmer and seemed to take everything I said in - as he realised he had to get back to his old self so that he could get back to the farm. This first day I was able to get him sitting out of bed in a big recliner chair.
When I walked in the next morning he saw me and groaned "not you again!" I knew I'd have a difficult day. I started be talking to him about things that were totally unrelated - his family, hobbies, farm etc. This seemed to calm him and lower his initial anxiety. His nurse who he'd come to know quite well joined in on the conversation which livened things up some more. I had already educated him and wanted to get him up walking. He tried everything to resist, even offering me money if I would go away! I assured him that he would be fine and there would be two Physio's with him the whole time. He finally agreed to walk as long as everytime he did, he could have a cup of tea - Something we were only too willing to do after the negotiating we'd been through. As he stood up I thought to increase motivation I'd let him feel like he had more control of the situation. I explained the oxymeter and as it rested in front of him on the trolley, he read the numbers out to me as he walker. I also showed him the oxygen cylender and allowed him to put on his nasal prongs himself, that type of thing. A lot of encouragement and a cup of tea later and he was happy. Each day became easier as he realised his capabilities and the need for cups of tea diminished too. By the end of the fifth day he was walking laps of ICU and was feeling really good.
I felt this patient was challenging as I had to try lots of different techniques to increase his motivation. I think a major hindrance was the fact he was in ICU where all the other patients around him were on ventilators and he didn't have that interaction that he'd have on a ward. I think he was bored, and just needed a bit of encouragement and support to get him going again. I've also learnt that the biggest motivator seems to be belief in oneself and if we as physios can impart that belief in our patients we'd have a much easier time when it comes to rehab.
