Yes, a while ago the right hand was a claw, and the left hand is getting worse too, because I’m mostly concentrating on my right hand,which has always been worse. I put the hand brace on my right hand at night, and in the morning I can straighten out my right hand with some effort. Then later I exercise both hands, opening and closing a fist several times. If I have time, I put my new robotic hand that I bought on Temu on my right hand, and it opens and closes my hand for a while. The hands actually got a lot better from that, but there was a pause where I couldn’t get my Radicava (endaravone) due to my insurance company having new requirements, so that by the time I resumed it, both hands had deteriorated somewhat again. So I think the Radicava may be a factor in how well your hands work, but I’m really not sure. I’m still actually able to sign my name, just barely, which I think may be due to the combination of exercise and medication. Hope this helps.
