Rotatory Chair Testing
Rotatory chair testing is a mid-frequency test of vestibular function, testing a range of different frequencies from 0.01 Hz to 0.64 Hz. Rotatory chair (head) speed is compared to eye movement speed to assess the vestibulo-ocular reflex (VOR).
Rotational chair testing for vestibular problems offers several diagnostic benefits. One of the primary benefits is its consistency in diagnosing patients with a bilateral vestibular weakness. Compared to caloric testing which is often considered to be the gold standard for identifying a unilateral vestibular loss, rotatory chair testing is considered the gold standard for detection of bilateral vestibular losses.
The rotatory chair is also useful in assessing children with vestibular problems .
