When there is a problem with the cerebellum, along with an intention tremor you also may have ataxia. I have very ataxic movement. Ataxia means a problem with coordination. Every time I was evaluated by a doctor, one thing they would have me do is touch my index finger to my nose then to their finger and repeat that a few times. This is called – cleverly – the finger to nose test. This is to test for ataxia and can also test for a tremor. I had problems doing that, still do. I can do it, but it’s a lot slower and less steady on my right side. When I go to push a button on the microwave I have problems coordinating that movement. I’m all over the place, my hand can’t go directly there. This is ataxia. Then when I get to where I want to be with my hand, like a button on the microwave, I start shaking because my intention tremor kicks in! It’s a double whammy. But it’s OK, it’s getting better.
