Hi, Greg. Maybe this trick would help you. Someone told me that rocking side to side prior to walking helps to improve start hesitation. It worked for me.

Then I tried THINKING side to side motion, as I walked straight ahead of me. I walked much better that way, thinking side to side, as if I were rocking side to side instead of walking straight.

It's hard to explain. When my gait is very poor, I focus on the lines ahead on the sidewalk and at the same time I think 'side to side' as if I'm rocking, like a metronome. and I walk much better than if I were thinking of just walking foward.

I've never had feedback from anyone else about this trick, but it works well for me. I think it may necessitate formation of a new feedback loop that works better than the usual one.
