That’s a very good video illustrating the hip weakness from LEMS. Personally I don’t recall if I looked like this when I had my initial crisis in 2009 and couldn’t walk or get out of a chair. Now I just look a bit stiff legged when my hips are weak. But, I have recently seen videos from two other LEMS patients who do now or have exhibited this amount of hip drop in their walks. It’s a remarkably visible sign of the hip weakness of LEMS.
