Advanced Vestibular Assessment

---

1.  Computerized Dynamic Posturography is useful for all of the following reasons except: allows assessment of balance in the medial-lateral direction has good reliability according to the established in the literature has limited operator bias during balance testing objectively measures a patient's balance

2.  A patient with normal automatic motor responses on the Motor Control Test would have a Comprehensive Report showing all of the following except: decreasing amplitude in relation to increasing translation size green Composite Latency Score responses occur in less than 150 msec symmetrical responses between left and right sides

3.  A patient with an abnormal Adaptation Test would have Sway Energy Scores that are: A bar graph below the shaded area for the Composite Latency Score higher during initial trials and decrease progressively lower during initial trials and increase progressively squares below the shaded area on toes up and toes down graphics

4.  The gold standard for the assessment of high frequency head impulse prior to the video head impulse test was the ___________________. Caloric exam Rotational chair exam Scleral search coil Vibration stimulation

5.  Clinicians administering the traditional head impulse were only capable of observing the______________. Covert saccade Overt saccade Gain Phase

6.  One of the parameters not measured during the vHIT examination is_________. Gain Presence of covert saccades Presence of overt saccades Phase

7.  McCaslin reported that in cases of Definite Menieres disease, it is possible to observe a significant _____________________ and a normal vHIT. Caloric weakness Bilateral weakness on rotational testing Directional preponderance Headache

8.  During rotational vestibular testing, which sensory end organs are being evaluated? anterior semicircular canal and the superior branch of the vestibular nerve posterior semicircular canal and the inferior branch of the vestibular nerve horizontal semicircular canal and the superior branch of the vestibular nerve only the horizontal semicircular canal

9.  What specific reflex is being evaluated and interpreted during rotational vestibular testing? The slow phase of the vestibular ocular reflex The fast phase of the vestibular ocular reflex The cornea ocular reflex Velocity storage

10.  VOR phase lead during low-frequency sinusoidal harmonic oscillation testing is largely due to what central function? The brainstem reflex Velocity storage The central ocular reflex Vestibular nuclei compensation

11.  Which of the following is not an advantage of rotational vestibular testing? Provides a more natural / broader frequency range that approaches every-day activities Limits stimulus artifact (noise) by providing a well-controlled repeatable stimulus Is not affected by lack of mental tasking It's good repeatability makes it ideal for monitoring small changes in vestibular function

12.  VEMP testing is a measure of: EMG activity modulated by stimulating vestibular afferents with an acoustic stimulus neuronal action potentials measured directly from the vestibular nerve action potentials elicited by activation of otolith function that results from eye movements, specifically upgaze action potentials elicited by activation of otolith function that results from movements and contractions of all the neck muscles

13.  The following describes the effects of age in c-and oVEMP results: lncreased asymmetry ratios, decreased thresholds, decreased amplitudes lncreased rate of absent responses, increased asymmetry rations, increased thresholds, decreased amplitudes Decreased thresholds, decreased amplitudes Lower thresholds, higher amplitudes

14.  For the diagnosis of Superior Canal Dehiscence Syndrome, the best VEMP measurement to use as screening or first step is: cVEMP thresholds in response to air conducted sound oVEMP thresholds in response to vibration or taps 500 Hz or click-evoked oVEMP amplitudes cVEMP raw peak-to-peak amplitudes in response to air conducted sound

15.  Patients with neurological disorders show which pattern of VEMP responses? low (normal) asymmetry ratios delayed cVEMP latencies only delayed c-and oVEMP latencies and/or absent c-and oVEMP responses to either vibration or air conducted sound increased oVEMP thresholds only
