Take some time now to watch this heartbreaking story of Desiree Jennings, a young aspiring cheerleader who has been crippled after getting a seasonal flu shot. It seems that the flu shot she received has triggered a rare neurological disorder known as Dystonia which causes her body to have uncontrollable muscle contractions. [via]
The weird thing about Desiree’s condition is that the symptoms of Dystonia disappear if she runs or walks backwards. In the video above, she demonstrates how she can go from completely normal running to uncontrollable body movements once she slows down to a leisurely pace.

have you came across the “walk it out” remix of this video?
No, but I don’t think I’d post it. Seems pretty insensitive to her situation.
she had a seasonal flu shot, not a H1N1 flu shot…
Post has been updated to reflect this new information. Thanks!
Oh noo, this is heartbreaking and completely bizarre. Poor girl :( I hope that researchers find a way to reverse this.
