Medline NLM definition, associated with the
MeSH term Torticollis: A focal dystonia characterized by a sustained
spasmodic contraction of neck muscles. The trapezius and
sternocleidomastoid muscles are primarily involved, resulting in twisting
of the neck and an unnatural position of the head. Torticollis may occur
as a primary disease process or in association with another condition
(e.g., NECK INJURIES, the use of ANTIPSYCHOTIC AGENTS, etc.)
