Bob, when someone crosses my path, I stop suddenly and it takes a moment to get going again. I think the intruder breaks my rhythm, such as it is.

Rick, I tried an experiment: walking with eyes closed, but doing my side to side thinking in my brain, i.e. as if I were moving side to side instead of straight ahead. And yup, I could walk.

I don't know why the side to side thing works for me. I think the loop controlling movement walking foward is defective.

But the one controlling side to side is not. Just like the loop for walking up stairs is intact. So, I access that side to side loop by thinking about it, and I can move foward with ease.

I'm not consciously thinking about moving foward, but that idea of moving foward may be automatic; it's the loop for the actual gait that is impaired, so I compensate for that by thinking side to side.

I wish others would try it and let me know if it works. When I get off the train, I always have trouble moving, but it gets much easier when I start to think 'side to side'. It's a nutty idea, but it works for me.

Please, try it and see if it works for you!

Michael, I'll explore your site soon!
