Velopharyngeal Dystonia: An Unusual Focal Task-specific Dystonia?
نویسندگان
چکیده
BACKGROUND Velopharyngeal dysfunction produces a nasal speech pattern because of the inability to close the nasal airway during speech, most often associated with anatomical abnormalities of the palate. CASE REPORT We describe two cases of possible velopharyngeal dystonia, a task-specific movement disorder causing a speech pattern similar to velopharyngeal dysfunction. Both patients experienced treatment response with anticholinergic medication. DISCUSSION Dystonia affecting speech via involvement of the pharyngeal musculature may be an unrecognized etiology of voice disorders.

In the limbs, focal dystonia can occur in either the upper or lower limbs and may be task-specific causing abnormal motor performance for only a specific task, such as in writer's cramp, runner's dystonia, or musician's dystonia. Focal limb dystonia can be non-task-s...
