Vanderbilt Audiology Journal Club: A Vestibular Update

---

1.  Both the video head impulse test (vHIT) and the dynamic visual acuity (DVA) test allow the clinician to gain information related to what reflex? Vestibulo-ocular reflex Vestibulo-spinal reflex Vestibulo-collic reflex Vestibulo-autonomic reflex

2.  Which of the following saccadic eye movements occur during the head movement while the clinician delivers impulses during vHIT testing? Overt Saccades Covert Saccades Hypermetric Saccades Cogwheel Saccades

3.  The study by Wettstein et al. indicates a significant correlation between which of the following results and better dynamic visual acuity performance in patients with unilateral vestibular impairment? Percentage of Overt Saccades Percentage of Normal VOR Gain Percentage of Covert Saccades Percentage of Head Impulses

4.  The study by Wettstein et al. also suggests that as amplitude of which parameter decreases, dynamic visual acuity performance in patients with unilateral vestibular impairment improves? Amplitude of Covert Saccades Amplitude of VOR Gain Amplitude of Head Impulses Amplitude of Overt Saccades

5.  How many neurotologists (board certified plus non-board certified) did Jacobson say there were in the United States? 1575 2051 721 323

6.  For which ear disease/disorder was the agreement between the DSP and the ear specialist (gold-standard) best? Meniere's disease Unsteadiness BPPV SCD

7.  Which of the following is not a potential problem with all case history type devices? They depend on accurate recall They require accurate somatic awareness They cannot be utilized for anyone over the age of 40 years The results of the DSP may be meaningless or at best ambiguous when patients over-endorse items

8.  Which of the following patients report driving difficulty? Patients with Meniere's disease or chronic vestibulopathy Patients that are overweight Patients with old cars Patients with allergies and food intolerances

9.  Patients with bilateral vestibular impairment report the following when driving: Difficulty changing lanes in traffic Impaired reading and processing signage Increased difficulty in low light (night or rain) All of the above

10.  Driving difficulty was reported often for those with reported vestibular dysfunction. Less Significantly less More Significantly more
