Vestibular function can be evaluated using various clinical and laboratory findings. Among these, head heave and vestibular evoked myogenic potential (VEMP) represent the otolith-ocular response, which is dynamic rather than static. There have been no reports of tap-evoked VEMP and head-heave in dizzy patients. Here, we report dissociation between ocular VEMP to head tap and the head heave test in acute vestibulopathy.
