[Gaze-evoked suppression of the vestibular-ocular reflex in patients with posterior cervical sympathetic syndrome].

This vestibulometric (sinusoidal rotation) study included patients with posterior cervical sympathetic syndrome (n=40) and with vestibular neuronitis (n=20) as well as 20 healthy subjects of the control group. Vestibular dysfunction was induced by the method proposed by de Klein. The patients with posterior cervical sympathetic syndrome in the decompensation phase displayed abnormal gaze-evoked suppression of the vestibular-ocular reflex when their head movements lined up with sinusoidal rotation. This symptom is considered to be of primary value for the diagnosis of vestibular dysfunction in these patients.
