Home physical therapy. Any suggestions?

Ask her PCP for a referral for home health. Medicare should pay for these services, but she may need to make an office visit first because the PCP needs to document this as a health issue.
If that does not work, you can buy resistance bands online and those small exercises help a lot. Buying weights or balls also help. When my grandpa was in a rehab facility, one of the group exercises was to throw a bouncy ball to others in a circle. You could do that with her. Or, you could hire a caregiver for a bit as a lot of them are trained in light PT and learn from them. There are many handouts online on simple PT exercises that one can do in bed or in a chair.

Braunfels, usually to get physical therapy your wife would need her primary doctor to write out a prescription for physical therapy. Ask the doctor if Medicare would cover for therapy.

As for finding a physical therapy group that will come to the house, you would need to call around. First try your local County/City council on aging to see what recommendations they can make.

At home therapy verses outside office therapy. My Dad had both. The at home it was limited what items the therapist could bring with him/her. At the office therapy, it was more like a small gym with machines to help with the exercises. Dad did much better going to the office for therapy. But that meant gather him up with his walker and driving there 3 times a week. Dad also had home therapy but that process was slow in his case.

If your wife has mainly male doctors, then see if she can get a male therapist. If mainly female doctors, then a female therapist. It's a comfort level.

I would start with her doctor. Ask for consult for therapy. The problem is that at some point physical therapy does not help; the senior is examined to see if it might. There is a level reached where physical therapy will not be covered due to a senior being adjudged to be at the highest level he or she is able to achieve. But start with a call to the doctor where you and your wife can discuss possible means of pain control so she is able to move better, and a consult with a physical therapist. Good luck. As a nurse I do know all about use it or lose it. Goes for balance, as well. Muscles begin to atrophy and tendons follow with tightening and the movement then becomes more and more impossible and full of pain. So much has to do with determination and motivation. You would be amazing how well seniors with stroke healed when allowed to play slot machine games with "one armed bandits". Ask around at the complex about Senior center classes where she might engage with others as well as do therapy. Buy some stretch exercise bands (on Amazon) and do some muscle work arm and leg together, gently, after permission from her doc.
