Bárány chair

A bárány chair is a special kind of chair that helps doctors figure out if a person has a problem with their balance. It's named after a doctor named Robert Bárány, who invented it in the early 20th century.

The chair looks like a regular chair, but there's a big difference - it can spin around in circles! When you sit in the chair, the doctor will spin you around slowly. This might feel a little bit like going on a merry-go-round at the playground.

While you're spinning around, the doctor will ask you to do different things, like move your head or your eyes, or touch your fingers to your nose. The doctor will also keep an eye on your eye movements. This might sound strange, but your eyes are connected to your inner ear, which helps you keep your balance. By watching your eye movements, the doctor can figure out if your inner ear is working properly.

The bárány chair is really helpful because it lets doctors do all of this testing in a controlled environment. They can spin you around as much or as little as they need to, and they can be sure that you're safe while you're doing it. Plus, the chair is really fun! Kids often love getting to spin around in the bárány chair, even if it's for a medical test.
