A video-oculographic study of XXXX .

@entity1 @entity2194 @entity388 @entity1017
OBJECTIVES: To quantitate the vestibulo-ocular reflex (VOR) gain in @entity1 with @entity388 ( @entity388 ) and repeat this daily using a portable video head impulse test device to assess vestibular recovery in the acute stage of @entity388 . MATERIALS AND METHODS: We enrolled adults with symptoms and signs of @entity388 presenting to the emergency department within 48 h of symptom onset. We recorded the eye movement response to rapid head impulses using the ICS Impulse(   ) video head impulse test device on each day of their hospital admission. RESULTS: There were eight @entity1 (75% @entity1 , aged 35-85 years) who had marked variation in their initial vestibulo-ocular reflex gains. Three @entity1 had vestibulo-ocular reflex gains in the normal range initially, despite having physical signs of @entity388 . Two @entity1 had initial contralesional gains below the normal range, associated with markedly reduced @entity1017 . Most @entity1 ' vestibulo-ocular reflex gains increased during admission, but four @entity1 ' @entity1017 remained in the abnormal range. @entity1 with @entity2194 were less likely to improve into the normal range. No @entity1 with initially abnormal @entity2194 recovered normal vestibulo-ocular reflex gain along with resolution of physical signs. CONCLUSION: Early video head impulse testing in the emergency department and each day of admission is feasible and well tolerated. There is marked variation in @entity2194 in @entity1 with symptoms and signs of @entity388 , and low initial VOR gains are a predictor for low VOR gains on subsequent days. Improvement in VOR gains was seen in most @entity1 .
