Vestibular hyperreactivity in patients with idiopathic spasmodic torticollis.
نویسندگان
چکیده
Ocular motor tests performed on 14 patients with idiopathic spasmodic torticollis were normal. The vestibulo-ocular reflex tested in eight patients showed a significant high level in seven. It is suggested that this phenomenon is secondary rather than the cause of spasmodic torticollis.

Spasmodic torticollis following unilateral VIII nerve lesions: neck EMG modulation in response to vestibular stimuli.
Three patients with spasmodic torticollis following VIII nerve lesions (VIII-ST) underwent quantitative assessment of their sternomastoid EMG during vestibular (otolith and semicircular canal) stimulation. The results were compared with a normal control group and with six patients with idiopathic spasmodic torticollis (ST). Backwards tilt of the VIII-ST patients resulted in a marked increase in...
متن کاملRole of the vestibular system in the pathophysiology of spasmodic torticollis
Idiopathic spasmodic torticollis is a form of focal dystonia aVecting the neck. It is characterised by involuntary repetitive or sustained neck muscle contractions leading to abnormal head postures and impaired control of head movement. With an estimated prevalence of 9/100 000 spasmodic torticollis is the most common focal dystonia. Onset peaks around the age of 40 and there is a female prepon...
