Vestibular Foundations - Ignore: Revision Table
This deck covers six key vestibular diagnostic tests, detailing their ability to diagnose peripheral and central vestibular disorders, key factors affecting testing, and patient instructions.
Gaze/ Spontaneous Nystagmus Test. Peripheral Vestibular Disorder (Yes/ No) Central Disorder (Yes/No) Key things to look out for: *Patient instructions: Key factors that could affect testing e.g. testing equipment, patient considerations This test would help diagnose (which condition/ pathology?)
yes it tests peripheral vesitb disorders yes it tests central vestib disorders look out for the direction the nystagmus beats in & are they >3degrees/ sec Patient instructions: keep looking at the target, try not to move your head or close your eyes Key affecting factors are: - no mascara, good lock on pupil - patient factors like fatigue, visual acuity, cooperation and suppressant medications this test helps diagnose both central or peripheral pathology

Head Impulse Test. Peripheral Vestibular Disorder (Yes/ No) Central Disorder (Yes/No) Key things to look out for: *Patient instructions: Key factors that could affect testing e.g. testing equipment, patient considerations This test would help diagnose (which condition/ pathology?) | yes this tests for peripheral vestibular disorders no, this test does not test for central vestibular disorders key things to look out for: which side gives you the corrective eye movements? OR is the response within normal limits? patient instructions: keep eyes open key affecting factors: no mascara, good lock on pupil -this test would help diagnose peripheral pathology on the side of lesion |
Dynamic Visual Acuity Test. Peripheral Vestibular Disorder (Yes/ No) Central Disorder (Yes/No) Key things to look out for: *Patient instructions: Key factors that could affect testing e.g. testing equipment, patient considerations This test would help diagnose (which condition/ pathology?) | yes it does diagnose vestibular disorders it RARELY helps diagnose central disorders key things to look out for: Normal: no change or decrease by one line Abnormal: Decrease by 2 or more lines on the chart Patient instructions: ‘ read the lowest line on the chart with your head still, then again while your head is moved rapidly side to side, up and down and rotationally’ Key affecting factors: - chart placement at a consistent distance, rapid head movement by the clinician and patient cooperation. This test helps diagnose bilateral vestibular hypofunction, impaired VOR |
