Classification of Dystonias and their Causes

Dystonia is a complex condition with various types and causes. Sensory involvement and inhibition play a role in its development. Different types of dystonias, such as focal, generalized, and task-specific, help determine its underlying cause. For example, focal dystonia can be related to overuse in musicians or writers. In some cases, dystonias can be triggered by specific activities like holding a golf club or pitching in baseball. These unusual manifestations have led to the consideration of functional causes.
