Here are a few things I have found that work for me.

1. Try to take big steps.
2.. If I can I slide my feet on the floor like a skier.
3. use some sort of chant as I walk... 1,2,3,4 put my heel on the floor.
4. sit on my butt and use a power chair, hover round or whatever.
5. ASK someone else to help me. Lots of times we don't ask for help. Others are there, they just need to know what you need.
