Spasmodic torticollis (cervical dystonia) is a type of dystonia where there
is spasmodic turning of the head and neck to one side. The muscles involved -
trapezius and sternomastoid - may become hypertrophied. There may be dystonia
Prevalence of spasmodic torticollis is 0.006% (5.7 per 100,000)
In the acute presentation there may be
sudden pain and an inability to move the head. Commonly the condition occurs in
the 15-30 age group. Passive and active movements are restricted. The head is
typically held in a position flexed away from the pain.
- spasmodic torticollis
is a chronic neurological disorder characterized by involuntary contractions of
the cervical musculature that lead to abnormal movements and postures of the head
- additional symptoms can include jerking movements, transient spasms,
shoulder elevation, stiffness/tightness, and tremor
- at least two-thirds
of patients report pain that significantly contributes to the disability associated
with their disorder
- pain is most frequently localized to the back of
the neck and shoulders
- may also involve the head, upper chest, upper arms,
and other areas
Spasmodic torticollis (cervical
dystonia) is rarely self-limiting. Treatment options include botulinum toxin injections
into the affected muscles.
