Benign paroxysmal positional vertigo clinical, oculographic and postural features

ABSTRACT

Benign paroxysmal positional vertigo [BPPV] is the most common cause of vertigo of peripheral origin. Clinical, oclulographic and postural features in 212 patients with BPPV were reported. For all participants, history taking, Frenzel glass visualization of nystagmus, electronystagmograph [ENC] and sensory organization test [SOT] were performed. Females outnumbered males. The peak of incidence occurs in the six decade of age. The majority of cases belong to the idiopathic group. Abnormaities in calric testing were found in 42% of participants. Only 2 patients had central ENG results. SOT quantifies the patient's ability to maintain balance when visual and/or somatosensory cues are either absent or inappropriate
