[Pseudo-Sclerosis (Struempell-Westphal)]

[A young woman sits in a wheelchair.  Her body shakes and trembles.]

[She rapidly flutters her finger at the tip of her nose, raising and lowering her arms several times.]

[She attempts to hold her arms and hands in front of herself in a controlled fashion. They tremble, then she slowly flutters them.]

[A man in a white coat places a stick in front of her, parallel to her shoulders, and she drapes her hands over the stick.]

[She holds her arms out to the side and flaps them up and down.]

[More hand and arm movements are performed, shaky and uncoordinated. Footage switches to slow-motion.]

[A finger pulls down her lower eyelid and her eyeball is shown moving jerkily.]

[She is walking outdoors with the help of an attendant.  Her gait is unsteady.]

[She stands on one leg with the help of an attendant, and her free foot jiggles. Her head moves as well.]
