Another atrophy question
My neuro says he can see the atrophy in my left hand. It is obvious to me and to anyone looking at it. But what I dont understand is that other than the fact that it feels odd (whch is the only way I can describe it), it seems to function pretty well. I can still do everything with it, I think. It is hard because I am right handed and so I have never really noticed what my left hand can and cannot do.
My question is this, how much atrophy does there need to be before the hand loses some motor skills. Can you pretty much lose all of it before there is what might be described as clinical weakness. Or typically, would you expect in ALS for the weakness to precede the atrophy or do they happen simultaneously. I am just confused about this.
My neuro looked at it and said he could see the atrophy but when he strength tested it, his response was "hmmm, strange, you still have good strength in that hand." I think he was as confused as I am! Any insight?
