ICS Impulse – Revolutionizing Vestibular Assessment

---

1.  What is head impulse? Side of lesion specific test (can identify which side the vestibular disorder resides on) Test that detects disorders of the vestibulo-ocular reflex (VOR) Test of peripheral vestibular loss All of the above

2.  What are overt catch-up saccades? A corrective saccadic eye movement (a “catch-up” saccade) after the head impulse that can in most cases be identified by the naked eye A corrective saccadic eye movement (a “catch-up” saccade) during the head impulse that cannot be identified by the naked eye A corrective saccadic eye movement (a “catch-up” saccade) that occurs minutes after the head impulse has ceased None of the above

3.  What are covert catch-up saccades? A corrective saccadic eye movement (a catch-up saccade) that occurs minutes after the head impulse has ceased and can in most cases be identified by the naked eye A corrective saccadic eye movement (a catch-upsaccade) during the head impulse that cannot be identified by the naked eye A corrective saccadic eye movement (a catch-up saccade) after the head impulse None of the above

4.  What is one indication of a normal response on a head impulse test? The absence of catch-up saccades The presence of catch-up saccades A low gain None of the Above

5.  What is another indication of a normal response on a head impulse test? The presence of catch-up saccades A gain close to 1 (between 0.8 and 1.2) A low gain None of the Above

6.  What is one indication of an abnormal response on a head impulse test? The absence of catch-up saccades The presence of catch-up saccades A gain close to 1 (between 0.8 and 1.2) None of the Above

7.  What is another indication of an abnormal response on a head impulse test? The absence of catch-up saccades A gain close to 1 (between 0.8 and 1.2) A low gain when comparing the head and eye velocity All of the Above

8.  What anatomical structure(s) may be affected in a patient with superior vestibular neuritis? ( Utricle Superior vestibular nerve Lateral semicircular canal Anterior semicircular canal All of the Above

9.  What anatomical structure(s) may be affected in a patient with inferior vestibular neuritis? Utricle Posterior Semicircular Canal Superior vestibular nerve Lateral semicircular canal

10.  What other anatomical structure(s) may be affected in a patient with inferior vestibular neuritis? Superior vestibular nerve Inferior vestibular nerve Lateral semicircular canal Anterior semicircular canal
