Cervical Dystonia: Rotational Torticollis
Cervical dystonia (CD), also known as spasmodic torticollis, produces several varieties of abnormal head posture. The most common of these is rotational torticollis. In many patients, there is an associated laterocollis, usually to the side opposite the rotation, which creates the image of “a robin looking at the worm.” In some cases, the laterocollis may be ipsilateral to the side of rotation. The second most common abnormality of head posture is laterocollis which is typically associated with shoulder elevation ipsilateral to the direction of head tilt. Pure retrocollis and anterocollis are less common forms of CD and more often occur in combination with rotational torticollis or laterocollis.
