These are the obstacles that persons with disabilities face. Obviously, reality does not fit neatly into a conceptual scheme, but looking at it in this way helps distinguish between the components of care based on the characteristics of the subject and shows that the objectives, as well as the strategies for implementation, are different in each case. Elderly persons (aged 80 or over) and persons of any age with health- or disability-related dependence are in the fragility-autonomy quadrant; their care should focus on providing targeted, technical support that manages their dependence in the best possible way and compensates for their current or potential limitations. The fragilization-autonomy quadrant has to do with the quality of care and preventive measures; requirements include changing the physical and social surroundings, providing services for an ageing society and addressing the obstacles that persons with disabilities face.
