Some showed a new saccadic strategy that may have potential for explaining how patients use saccades to recover from vestibular loss. METHODS Eight patients with severe BVL [vestibulo-ocular reflex (VOR) gains less than 0.35 and absent o...

متن کاملBilateral Vestibular Hypofunction in Quantitative Head Impulse Test: Clinical Characteristics in 23 Patients.
OBJECTIVE To explore clinical features of patients with bilateral vestibular hypofunction (BVH) verified in motorized head impulse test (MHIT). MATERIALS AND METHODS We examined clinical records of 23 adult patients (10 males and 13 females), whose gain of the vestibulo-ocular reflex in the MHIT was bilaterally lowered. Fifteen of 62 unilateral cochlear implant (CI) recipients routinely teste...
