I am like 2Fight, ruptured Fisher Level 3 which is more than 1mm of blood in the subarachnoid space. I was in ICU for 26 days. I am one of the lucky ones.
I’m so sorry about your sister and the troubles you and your mother are dealing with. What happens when someone is bed ridden for so long is their muscles atrophy because they aren’t using them. It is very painful. Basically the muscles draw up or are rigidly straight. At the least, they will be doing Range of Motion exercises which forces the muscles to work. ROM can be painful as well, tell your sister to keep fighting. She needs to do her exercises all the time, even when the PT or PTA or the CNA isn’t doing them for her if she is able. There are other factors such as circulatory and respiratory issues that occur when someone isn’t moving. Back decades ago, I was a CNA going through college. ROM had to be done ideally every hour on every bed ridden patient. In the real world, it was every 2-3 hours. If a patient was alert and could follow directions, I would have them do things that could help themselves. We didn’t have a physical therapist in that facility. If they weren’t responsive, we had to move their arms, legs, neck, wrists, fingers, toes.
My doctor had these air wraps put around my lower legs in ICU for several weeks, I liked them as they took the pain out of my legs. They would inflate and deflate in a rhythmic pattern. They help with circulation and contraction of muscles. The ICU RNs told me most people don’t like them.
Here’s a paper about muscle atrophy https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4315632/
As 2Fight suggested, get a meeting with the rehab, they should have team meetings on a regular basis. They allot about 10-15 minutes per patient. It’s fast, so have notes ready.
In the US, there is a Medicare ombundsman who can help navigate long term care. In MA, this is their link https://www.mass.gov/service-details/ombudsman-programs
There may also be a Social Worker in the facility who would be a good person to connect with. Talk to the Physical Therapist in charge of her PT. I would start with them first. Don’t let them dismiss your concerns. You can probably get a little longer meeting with the SW than with the PT. But start with the PT first so you can really understand what your sister is going through and what needs to be done. The PT will have set both short and long term goals for her.
Good luck and keep us posted!
