"Trick" movements in facial dystonia.
Two patients with facial dystonia (blepharospasm and/or oromandibular dystonia) presented with an unusual "trick" movement. Both patients were able to inhibit blepharospasm and oromandibular dystonia by vocalizations including singing, reading, and speaking spontaneously. The significance of "trick" movements in facial dystonia is discussed.
