Take the PR to an orthopedist to see if anything can be done to relieve the cramping in her hand.
Follow-up. The doc said the pain/cramps may be from the way she is cradling that hand under the other arm. Said any surgery would be strictly cosmetic because she doesn't have use of her fingers and surgery wouldn't give her use of them. Therapy and a splint were recommended.
I wonder how a splint would stop her hand from cramping, because she couldn't cradle it under the other arm with a splint on it?
A well formed splint will "force" the hand to relax.
I have slept with a splint for that reason for a while. Was only allowed to use it during the night. It also taught me to keep my hand more relaxed during the day.
First time I had the splint on, it felt like a long longed for warm bath. The pain, that I had been ignoring for a very long time, dropped in seconds with more than 50%. Nearly brought tears to my eyes, that shock of de-cramping.
Was a bit of a nuisance to learn to sleep with it. But, I still have it around somewhere, and, when I notice the cramping up is starting again, I sleep with it for another few nights.
Should get my splint re-adjusted. But, since I now use it so rarely, I can't be bothered.
