Brief description
Spasmodic torticollis is an involuntary movement disorder of the neck, involving sustained or intermittent muscle contractions that result in twisting and repetitive movements or abnormal postures.
Confirming the diagnosis
Diagnosis is based on the clinical features. There are no specific diagnostic tests.
The relevant medical speciailist is a neurologist.

Conditions not covered by SOP

Clinical onset
Clinical onset will be when the pattern of involuntary movements, subsequently confirmed to be due to spasmodic torticollis, first manifest.
Clinical worsening
The only SOP (worsening) factor is for inability to obtain appropriate clinical management. Available treatments are directed at relief of symptoms but do not alter the underlying pathology of the disease.
