Rotating Barany chair

Made:
circa 1950-2005

Rotating Barany chair, with control panel, laser attachment, archival material and other accessories. The Barany Chair was used to produce nystagmus (rapid, jerky eye movements) for clinical assessment of vestibular function (ie relating to body equilibrium and balance) including vertigo. This example was developed in the early 1950s, using surplus WWII hardware, for Charles Hallpike one of the founders of modern neuro-otology. It was originally used at the National Hospital in London. It remained in use until the summer of 2005.
