Is this a possible symptom? My wife raises her arm up high for no apparent reason. It looks like what I would do if I was releasing my shirt from under my trousers - an unusual analogy, I know, but it looks like that. She is doing this way too often. Thanks.

Yes, it could be an involuntary movement.

The way I thought of it, when my son first started raising his arms, was that he looked as though he was raising his hand for a teacher to call on him in school. Now he's raising both arms involuntarily. I don't say anything to him; it's just something that he does and can't help. His father did the same with HD so it doesn't surprise me. Don't worry about it, ok? It is what it is...
