In a world-first study, researchers at the Brain and Mind Research Institute (BMRI) at the University of Sydney may have found a new way to help the Parkinson’s disease patients who experience walking problems.Researchers are hoping to use a simulated virtual reality environment to help patients suffering from the phenomenon known as ‘freezing of gait’ (FOG). FOG affects over half of all Parkinson’s patients, and is commonly triggered by having to walk through narrow doorways.
