Vestibular, Visual Acuity, and Balance Outcomes in XXXX With Cochlear Implants: A Preliminary Report.

@entity1 @entity393
OBJECTIVES: There is a high incidence of @entity393 in @entity1 with cochlear implants (CCI). However, the relationship between @entity393 and various outcomes is unknown in @entity1 . The objectives of this study are to (1) determine whether age-related changes in peripheral vestibular tests occur; (2) quantify peripheral vestibular function in @entity1 with normal hearing and CCI; and (3) determine whether amount of @entity393 predicts visual acuity and balance performance. DESIGN: Eleven CCI and 12 @entity1 with normal hearing completed the following tests of vestibular function: ocular and cervical vestibular-evoked myogenic potential to assess utricle and saccule function and the video head impulse test to assess semicircular canal function. The relationship between amount of @entity393 and the following balance and visual acuity outcomes was assessed: dynamic gait index, single-leg stance, the sensory organization test, and tests of visual acuity, including dynamic visual acuity and the gaze stabilization test. RESULTS: (1) There were no significant age-related changes in peripheral vestibular testing with the exception of the n23 cervical vestibular-evoked myogenic potential latency, which was moderately correlated with age. (2) CCI had significantly higher rates of @entity393 for each test of canal and otolith function. (3) Amount of @entity393 predicted performance on single-leg stance, the dynamic gait index, some conditions of the sensory organization test, and the dynamic visual acuity test. Age was also a contributing factor for predicting the performance of almost all outcomes. CONCLUSIONS: Preliminarily, @entity1 with @entity393 do not recover naturally to levels of their healthy peers, particularly with activities that utilize vestibular input; they have poorer visual acuity and balance function.
