Or patients with Tick disorders can "hold" them for a while, but then they will burst out.

Other examples of temporarily overriding movement disorders: Michael J. Fox tremors up to the skating rink, but as soon as he steps on the ice, you can't tell he's sick. There's a video of an old man with Parkinson's who can barely hobble down the hall, but hops on a bicycle and tootles around the parking lot like a young boy. Scott Adams, creator of Dilbert, has spasmodic dysphonia (a form of dystonia with involuntary spasms of the vocal chords) and he couldn't talk, unless he put on a phony British accent, then he could suddenly speak.
