ParkWalker virtual imagery glasses

Filed under: Neurology , Rehab

BBC News reports about the Parkinson's hope over 'glasses':

A pair of glasses which use virtual imagery could help people with Parkinson's disease cope with walking problems, scientists say.

The device uses light to project images in front of the user, helping them to focus and control their movement.

Researchers at Oxford Computer Consultants are now putting the headset forward for clinical trials.

Some people with the disease suffer from freezing, which renders them unable to move once they stop.

The headset, which could cost £1,400, works by producing visual clues - an accepted method of combating freezing.

People with Parkinson's who freeze can be prompted to start walking again if objects are placed in their way and they have to walk round them.

Lights from the headset create a tunnel-effect, which enabled users in the initial testing stage to focus on the virtual imagery and move more freely.
