If this lady has been immobile for 2 years I have a suggestion. What motivates her? What really makes her happy? Does she read, paint, do knitting, does she socialise? I would begin to wonder if this lady was depressed and to have lost the will to move. In cases like this I look for the highest form of emotional motivation, that process which will help her overcome the discomfort it will possibly cause her to get back to where she was. Let her lead. If you show her activities with her wrists, arms, hips, and she demonstartes that she is compliant then maybe she will try working on the area which is problematic. To stand she will need pliable hips and lumbar spine. She will need strong arms for a frame, she will need inner stength as well. If she has good family and frinds she will move is she is motivated. However family can often do to much, or a residential home may simply be giving her the gentle love and care she has never had. In which case why should she change? I find that a sitting class with a group outside the hospital setting works well.
