The Virtual Reality ‘Could Help Treat Vertigo’

Virtual reality could be used to diagnose and treat visual vertigo, according to a team of Cardiff University psychologists.

A team of psychologists is working to develop virtual environments to help with diagnosis and rehabilitation.
The scientists believe the approach has “real potential”.
Dr Georgina Powell, of the School of Psychology, said: “We don’t know very much about what causes visual vertigo at the moment.
also are not many effective rehabilitation therapies available, so the
aim of our project is to try and understand those two things.”
said vertigo can be extremely debilitating, adding: “It can mean that a
patient can’t leave their house because they feel so sick and nauseous
every time they walk around in their visual environment.                   
The team said one of the most striking observations they had made
about sufferers was the variation between what sparks their symptoms.
the patients are very different and some environments might trigger
symptoms for some patients whilst other environments might trigger
symptoms for others,” Dr Powell said.
“So by using virtual
reality (VR) we can have vast flexibility over the different types of
environments that we can show to patients and we can find out what their
individual triggers might be and then tailor specific rehabilitation

‘We have a bucket ready’

vertigo is often referred to as “supermarket syndrome” because large
shops, with their cluttered shelves and repetitive aisles, can act as a
catalyst to attacks.

environments include walking by the side of a river, where you have
motion one side of you but not on the other,” Dr Powell said.
“Generally they can only handle so much of the virtual reality images at one time – we have a bucket ready,” She added.
“But we give them lots of breaks and lots of water and monitor how they are feeling.”

What is vertigo?

  • Vertigo is a symptom rather than a condition
  • Sufferers can endure dizziness, a sense of self-motion, a loss of balance and nausea
  • If you have severe vertigo, your symptoms may be constant and last for several days or even longer
  • The term vertigo is often incorrectly used to describe a fear of heights, which is actually acrophobia

Often, people with visual vertigo develop vertigo
after suffering damage or illness related to their vestibular system –
the apparatus of the inner ear involved in balance and space orientation
– such as an ear infection. It can also be related to migraines.

are new patients every month and also repeat patients. So, because it
can’t easily be fixed quickly, then the patients have to be seen
multiple times – that takes up a lot of NHS time.”
He said the concept had “real potential”, especially as virtual reality becomes cheaper.
