IT Project Offers Help To Parkinson’s Sufferers

One in twenty people who are paralysed by Parkinson’s disease could soon be
able to walk thanks to the PARREHA project, funded with the help of 1.68
million euros from the Information Society Technologies (IST) area of the
EU’s Framework Programme.

With two in every 1000 people suffering with Parkinson’s disease, a disorder
of the central nervous system, there are currently 700,000 people affected
in the European Union alone – and this number is forecast to increase as the
population gets older. Parkinson’s is caused by the loss of brain cells that
produce dopamine - a chemical messenger responsible for transmitting signals
within the brain – leaving sufferers unable to direct or control their
movement in the normal manner. This is why many people who have Parkinson’s
have difficulty walking in conditions that would normally present no
problems - such as an unobstructed corridor.

Ironically, scientists have discovered that when visual ’obstructions’ -
often as simple as pieces of paper set down on the floor - are placed in
their way, some people with Parkinson’s can walk normally. This little
understood effect is called kinesia paradoxa. PARREHA utilised the
development of virtual reality technology to develop a light headset that
enables the wearer to see the virtual visual cues wherever they look and at
the same continue to see their actual surroundings.

“This type of lightweight, wearable headset has a display that is very small
and looks like a normal pair of glasses”, explained project co-ordinator Dr
Reynold Greenlaw, from Oxford Computer Consultants. “Our headset enables a
number of people with Parkinson’s to move freely and more safely in their
normal environment. This is a major achievement, especially when you take
into account that falling is the second greatest cause of death in people
with Parkinson’s disease. It will be of special interest to people suffering
from vascular Parkinson’s as they do not currently have the option of drug
therapy.

“In a series of trials and exhibitions during the project we demonstrated
how the headset helps. After trying to walk unaided in an unobstructed
corridor, the user put on the virtual reality glasses. Through these they
see both the corridor and a series of brightly coloured stripes that scroll
slowly towards the viewer as if they are walking down a tunnel. Working with
the Parkinson’s group, Europark, we showed this device was highly effective
for a certain group of people with Parkinson’s. It has an enormous effect on
their quality of life and does not rely on any drugs or surgery."

The commercial partners in PARREHA have now formed a company called ParkAid
(http://www.parkaid.net), based in Italy, to work with manufacturers of
wearable computer displays. The latest prototype device won the EU’s 2004
‘New Territory’ prize for Assistive Technology (http://www.parkaid.net) and
the Institute of Neurology is now undertaking a two-year clinical trial into
its effectiveness. The equipment should soon be certified and, although
exact pricing has yet to be set, Dr Greenlaw estimates that the equipment -
including the headset, PDA and special software - will cost around 2,000
euros.

“This is another example of how information society technology is being
developed, with the help of EU Framework Funding, into applications that
reach way beyond what are considered the normal boundaries of computer
buffs”, says Peter Walters, FP6UK’s National Contact Point for IST. “It
shows how valuable research and development work can be in improving the
quality of life for many of us.”

“The Framework Programmes are the EU’s main vehicle for support of leading
edge, internationally collaborative R&D. The current Framework Programme
(FP6) runs until 2006 and organisations wanting free information on how to
access some of the €19bn available should log on to http://fp6uk.ost.gov.uk
or call central telephone support on 0870 600 6080.”
