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… (More)
