1
Q
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?)
A
- 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
2
Q
Saccade 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?)
A
- no it doesn’t test for peripheral
- yes it tests for central disorders
- key things to look for:
- are the results within normal limits or not
- patient instructions:
keep head still - key affecting factors:
- no mascara, good lock on pupil- keep head still, only move eyes.
- patient factors like fatigue, visual acuity, cooperation and suppressant meds
- this tests helps diagnose ONLY central pathology
3
Q
Smooth Pursuit 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?)
A
- this test does not test for peripheral disorders
- this test does test for central disorders
- key things to look out for: are the results within normal limits or not?
- patient instructions:
keep head still- follow trace as smoothly as possible - key affecting factors:
- no mascara, good lock on pupil- keep head still, only move eyes.
- patient factors like fatigue, visual acuity, cooperation and suppressant meds
- this tests helps diagnose ONLY central pathology
4
Q
Post Head Shake 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?)
A
- yes this tests for peripheral vestibular disorders
- it SOMETIMES tests for central disorders
- key things to look out for:
- are there nystagmus presents?
- how many beats?
- patient instructions: keep eyes open
- key affecting factors:
no mascara, good lock on pupil - this test helps diagnose peripheral pathology on the side of the lesion
5
Q
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?)
A
- 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
6
Q
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?)
A
- 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
