Introduction: Recently, mechanical vibration on the neck has begun to be used to improve diagnostic sensitivity in patients who have vestibular disorders.
Method: We review results of studies of this stimulus in normal subjects and patients with vestibular lesions: the ocular responses, changes in the subjective straight ahead, and postural changes generated by the neck vibration.
Conclusion: Although the underlying mechanism for the responses to neck vibration remains uncertain, it is an excellent addition to the neurotologic exam since it allows us demonstrate vestibular deficit with greater sensitivity than other maneuvers. As vibration is easy to apply it can be useful for screening in patients who complain of dizziness.
