What is the most common form of focal dystonia?
The cervical region is the area most frequently affected by dystonia.
Among 1000 patients with dystonia at the Baylor College of Medicine Parkinson’s Disease Center and Movement Disorders Clinic, 76% have cervical dystonia either alone (33% patients) or associated with involvement of other areas. It is slightly more common in women (61%).
Depending on the muscles involved, different types of postures are observed. Most patients with cervical dystonia have a combination of abnormal postures, such as torticollis, laterocollis, and anterocollis.
Pain is a feature in about 70% of the patients with neck dystonia, whereas tremor, either dystonic or essential type, is observed in 60%
