What is the head shaking test for vestibular?
Head-shaking nystagmus (HSN) is induced by oscillating the head at high frequency in the horizontal plane. This test is used in the clinic to detect the presence of a unilateral loss of vestibular function.
What causes head shaking nystagmus?
Background: Head-shaking nystagmus (HSN) occurs in both peripheral and central vestibular disorders. In most cases, HSN can be attributed to an asymmetric peripheral vestibular input or a structural lesion mostly in the cerebellum affecting the central velocity storage mechanism.
What is head shaking nystagmus test?

What is normal head impulse test?
The head impulse test (HIT) is a useful bedside examination to identify a peripheral vestibular deficit for example in patients with vestibular neuritis (VN). The clinician briskly rotates the patient’s head to detect “overt” catch-up saccades after head rotation as a sign of semicircular canal paresis.
