I was watching Inside Edition tonight and they had a story of a lady (she was young....probably early 20's) who had a flu shot then developed severe dystonia. She could barely walk - but what was so strange is that she could walk backwards just fine. And she could run. But walking forward was almost impossible. Her speech was affected, too. Except when she was running and then she could speak normally. Strange!

Here's the story:
