Hey Kathy I thought I was the only one who does the chicken dance!! I almost get into a fit of giggles when my neuro asks me to do it, cos I feel like humming the music and doing the rest of it, but he "would not be amused!!" we do have a good doctor patient relationship tho, which I should have after 6 years.

All the tests you mention are great for testing for weakness.
Another good test is laying flat on the ground and trying to sit up, no assitance, no bending knees, I do this when I think I'm feeling bad, and it confirms it.

hope this helps a little
