Cervical Dystonia

 Cervical dystonia, the most common form of focal dystonia, is characterized by abnormal squeezing and twisting muscle contractions in the head and neck area. Sustained muscle contractions result in abnormal positions or posturing.



Spasticity is a condition in which certain muscles are continuously contracted. This contraction causes stiffness or tightness of the muscles and may interfere with movement, speech, and manner of walking.



The term blepharospasm ['blef-a-ro-spaz-m] can be applied to a forced, sustained, and involuntary closure of the eyelids. It stems from a number of causes, beginning with dry eyes, and, may progress to a state where the person is "legally blind".
