Abstract

Retrocollis often occurs as a partial component of cervical dystonia and much less commonly as an isolated manifestation. It may produce either a tonic sustained retrocollic posture or may cause recurrent clonic vertical head jerks. When part of a complex dystonia, it is more commonly associated with laterocollis than other postural abnormalities. Isolated retrocollis is a common manifestation of tardive dystonia where it is commonly associated with extracervical dystonic manifestations and spasmodic head jerks.

The patient displays continuous tonic retrocollis together with a compensatory thoracic kyphosis. Vertical dystonic head jerks appear when she is asked to flex her neck. She displays an effective sensory trick with relief of retrocollis appearing just before and during placement of the fingers of her right hand beneath her chin (see  Chap. 43).
