Focal Dystonia

Focal dystonia is a neurological condition that affects a muscle or group of muscles in a specific part of the body causing involuntary muscular contractions and abnormal postures. For example, in focal hand dystonia, the fingers either curl into the palm or extend outward without control. In high level musicians, focal hand dystonia is referred to as musician's dystonia and focal dystonia in sports is commonly referred to as (the) yips. It is believed that all adult onset dystonias are a product of combined genetic factors and environmental modifiers.
