Description Rotary chair testing includes rotation around a vertical axis, and evaluates the horizontal semicircular canal vestibulo-ocular reflex (VOR). The patient sits in a mechanized chair with the head secured in a neutral position or in 30 degree forward flexion (to better isolate the horizontal canals). The chair is located within a cylindrical chamber, which excludes outside light (Figure 1). Eye movements are recorded with either videonystagmography (VNG)/videooculography (VOG) or electronystagmography (ENG). The chair is then rotated, commonly in one of two paradigms.
