HY, I've got a patient with ME at this time only saw her 2 times but anyway my strategie at this point is to give her opportunities to become more active. In fact this is simple but may depend on the way you bring your info. to the patient, so I do very simple excercises with her all within her capacity and tell her that she's able to increase them just a bit (at home; for starters) and the most important thing is to try and let her see that she can do things and will be tired but she's got a choice : do things and maybe be tired or don't do things and maybe be tired as well .... anyway what I'm trying to make clear is that patients sometimes just have to ignore some of their symptoms (a bit)
There might be some info on biomedline
Cheers
