A focal dystonia that affects the upper extremity and tends to occur when the patient is writing or doing other specific tasks, such as typing or shaving. The hand tends to curl and cramp, making the task difficult. Other dystonias, referred to as task-specific dystonias, occur when a body part develops abnormal posturing during specific movements, such as playing a musical instrument. It is often treated similarly to writer's cramp.
