For the past few years I have noticed that when I try to hold something in my hands they will ***k even though I have held the item only a few seconds and then the hand will slightly ungrasp the item causing it to fall to the floor. This happens to both hands. Lately though I have noted my legs when I tighten the muscles will do the same thing, ***k as though they are too weak to maintain the muscle tightening. This is especially bad in the hands first thing in the morning but does occur throughout the day. Any ideas what this could be? I had a cervical neck fusion in 1985 c5 and 6 but the problem started several years after the fusion. I am 61 years old. Any ideas what this could be?
