I survived a NASA-Ames Research Ceneter Helicopter Accident 9-11-81. I finally found Dr. Zhu in July 07. My hip was frozen – would not shift or rotate. My ankle collapsed frequently and my left toes were frozen so I could not move or use them. My right knee was so painful from a severe misalignment I could not use it. My left thumb was spastic- so no left hand. Now I am normal, beautiful movement and no fear. Thank God – I feel alive.
