 Focal dystonia affects one body area and includes blepharospasm, oromandibular dystonia, spasmodic dysphonia, torticollis, and limb dystonia. Focal dystonia typically presents as task-specific muscle spasms or occupational cramps in which learned or repetitive motor tasks such as writing or playing a musical instrument trigger muscle spasms and interfere with performance while other actions remain normal. Writers cramp is the most common form of idiopathic limb dystonia 1-3 where involuntary muscle activity and abnormal postures affect the arms and hands, but virtually any part of the body may be affected, even the lips when playing a woodwind or brass instrument 4. Patients may develop two focal dystonias but rarely does focal dystonia progress to more generalized forms.
