Focal Dystonia

Focal dystonia is sometimes called ‘musician’s cramp’, but it is not a primarily muscular problem: it begins in the brain1. As neuroscientist Jessica Grahn of the University of Cambridge, UK, explains, it stems from the fact that intense musical practice can overinflate the mental representation of the relevant part of the body (usually the fingers, although it can affect lip control in brass players). Once the neural representations of the fingers overlap, they can no longer be controlled independently.
