I completely agree with ukxmrv . Even those who can attempt some activity (or even exercise for the wellest ones), any increase however tiny could produce a catastrophic setback. Recommendations for increasing activity should certainly not be included. If we are able to attempt and tolerate anything to minimise deconditioning without compromising other priorities such as ADLs, housechores if we can manage them, and socializing, that's a good thing, but it should not be assumed that this is possible. And even in the cases where it is possible, any increase (if any) should come organically, and not because somebody thought it sounded like a good recommendation to rehabilitate people. We need decent medical treatments to rehabilitate us.
