Rick, I tend to lose focus when I'm stressed or exhausted. And when I lose focus, I lose my internal metronome ( the rhythm that I provide because my automatic rhythm is defective). When that happens, my movement suffers and I can shut down.

Distractions do the same thing. I can be walking okay, and if someone crossed in front of me, I freeze and have to get myself going again with great effort. The guy who passed me broke my rhythm. With focus and effort, I have to get the rhythm back.

When I'm anxious or upset, I feel discombobulated....like a doddering 100 year old.

When I move, I have to pay close attention when I step backwards or sideways (in the kitchen or lab, usually). If I don't do it slowly with great attention, I lose my balance. If I'm distressed, I may not focus like I should, and that could make me fall.

As for feedback loops, I think we need to provide our own feedback, to supply old loops, or to create new ones.
