Head Shaking Nystagmus Test | RehabMeasures Database
Nov 12, 2013 · Rapid head shaking and abrupt stopping may elicit nystagmus in patients with vestibular imbalance. It is recommended that the clinician tilts the patient’s head ~ 30 degrees downward, and then oscillates the patient’s head horizontally (passively) 20-30 cycles at 1-2 Hz.
3. Head Shake Test. (eyes closed: EC) Velocity storage integration; dynamic balance of labyrinths Eyes are closed and with 30º neck flexion (horizontal SCC position). Therapist shakestheir head side to side at 2 Hz(200-240bpm) for 20 cycles. Stop and then they open their eyes. Observe for nystagmus. Nystagmus; fast phase to intact side ...
Head Shaking Nystagmus - Dizziness-and-Balance.com
Jun 5, 2023 · Head-shaking nystagmus (HSN) is a jerk nystagmus that may follow a prolonged sinusoidal head oscillation. HSN was first described in 1907 by Robert Bárány (1907). Moritz called it "kopfschutteinnystagmus" (1951).
Head shaking test to diagnose vestibular disorders
The principle of the Head Shaking Test, comprising rapid head movements, either horizontally or vertically.

Head-shaking nystagmus (HSN): the theoretical explanation …
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.
Objective Vestibular Assessment - Physiopedia
The head shaking test is designed to increase any nystagmus caused by an asymmetry of the peripheral vestibular system. The response may be stronger in side lying but is generally performed in sitting. [15]
DOWNBEATING NYSTAGMUS (DBN) - Dizziness-and-Balance.com
Aug 1, 2022 · Provoked DBN. -- head-shaking, valsvalva, and positioning. Downbeating nystagmus can be elicited by the head-shaking test. This is also called "perverted" head-shaking nystagmus -- a nystagmus which is not in the plane of head-stimulation.
Head-shaking-induced nystagmus reflects dynamic vestibular …
We aimed to assess the ability of a head-shaking test (HST) to reflect vestibular compensation in patients after unilateral peripheral vestibular loss and to provide missing evidence and new insights into the features of head-shaking-induced nystagmus (HSN) over a 2-year follow-up. HSN may occur after a prolonged sinusoidal oscillation of the head.
Vestibular Tests: Head-Shaking Test | SpringerLink
Jan 1, 2024 · The head-shaking test is easy to perform at the bedside to detect a potential asymmetry between two horizontal semicircular canals. Compared to the caloric test, which detects a potential asymmetry in the low frequency range, the head-shaking test measures the function of the horizontal canalar ampulla in a middle frequency band.
