Vestibular testing-rotary chair and dynamic visual acuity tests

Research output: Contribution to journalArticlepeer-review


The human vestibular system is exquisitely sensitive to detect linear and rotational head acceleration signals, processed in the brainstem and subsequently relayed to the extraocular motor neurons to generate a compensatory eye rotation. This vestibulo-ocular reflex (VOR) ensures clear and stable vision during head rotation, enabling humans to keep gaze on their desired target. In this chapter, we describe the rotary chair - one physiologic measure of the VOR, and the dynamic visual acuity (DVA) test - one behavioral measure of the VOR. Advances in the use of each measure are covered and include establishing normative values, expanding into non-vestibular diagnoses, and broadening the application of each measure. These recent advances in rotary chair and DVA test methods help in extending our knowledge of this 3-dimensional motion sensor.
