Anyone who reads my blog regularly knows that I speak ad nauseam about the fact that I have an intention tremor. This is the opposite of a resting tremor. Everyone think of Michael J. Fox. Parkinson’s Disease causes a resting tremor. When Michael J. Fox is just sitting -resting- he shakes. The tremor comes out when he is at rest. When he performs a movement, the tremor subsides. At least that’s what I learned in school. I have no personal experience with Parkinson’s Disease and if I’ve learned anything it’s that book learnin’ certainly ain’t all it’s cracked up to be. Especially if you study neurology.
Anyway, what happens to me is the exact opposite. When I’m just chilling on the couch not doing anything, I can be completely still. It’s when I do something, like pick up a glass of water, that the tremor comes out. That’s why it’s called an intention tremor, it comes out with intent. So when I pick up a glass with my right hand, as the right side of my cerebellum is the damaged part, that glass better have very little liquid in it. Or else. My hand starts to shake. I’m really, really good at spilling things. Remember – cerebellum = same side of the body and cerebrum = opposite side of the body.
My vocal cords do the exact opposite. I had this test done where they stuck a camera down my throat in order to look at my vocal folds and they quiver at rest and calm down a bit when I make a sound. I think that’s really weird and I have no explanation for that. Anyone wanna take a stab at explaining that?
