RSI
in Children
The number of
recorded cases is still relatively low but many parents and health
professionals are concerned about the potential for RSI affecting
schoolchildren.
Schools often run health awareness campaigns for both children and
parents on subjects as diverse as asthmas, meningitis, drugs etc. RSI
Awareness believes there is a need for information on the dangers of
computer related injuries and that this awareness should extend to
teaching staff and governors. In particular, there is a need for advice
on posture, timed breaks and a proper ergonomic assessment.
The Body Action Campaign's tour of schools in England in 2000 found the
vast majority using tables which cannot accommodate the range of pupil
sizes, plastic bucket chairs and children with their legs dangling,
shoulders hunched, without back support and head back gazing up at the
screen. Recent schemes to provide schoolchildren with laptops do not
seem to take account of the increased health risks. A survey by Curtin
University in Australia showed that 60% of children suffered discomfort
when using their laptops. The pain, typically, was in the neck, lower
back, shoulders and head. The long term consequences of prolonged poor
posture on developing bodies are a major concern.
Children are also vulnerable to straining their hands and wrists. In
particular, the combination of keyboarding, playing computer games and
text-messaging needs careful attention from parents. Dr Diana Macgregor
of the Royal Aberdeen Children's Hospital has highlighted the case of
an 11-year-old boy who suffered from tendinitis following long periods
on his Nintendo GameBoy, a condition that has come to be known as
'Nintendonitis'.
Computer games are powerfully addictive and children's computing time
needs to be carefully managed. However, banning computer use entirely
is unreasonable and inappropriate. Measures such as rest and increased
variety of leisure pursuits will allow tendons and muscle to recover.
Dr Macgregor also recommends the use of preventative hand-care
exercises.
It should also be pointed out that children play games because they
want to - not because of any contract, job-target, financial imperative
or other work pressure. Without these complex social factors they are
at less risk of developing the chronic, prolonged hand diseases of
adulthood.
At home it is important to fit the chair to the child's body, not the
other way around. A fully-adjustable ergonomic chair is recommended but
even these may need a footrest. Failing that you can improvise by
placing a box or some books under the feet. Pillows and pads can take
up the extra seat room and provide something to lean against. The
keyboard should be around waist height and the child should not have to
look up at the screen (looking straight about 1 inch below the top of
the screen is best). This can sometimes be achieved by simply moving
the monitor off the computer base. Please refer to the ergoanswers for
kids website below for more information and handy hints.
Most schools cannot afford special furniture for their computers but a
good ergonomic set-up can be created on the smallest of budgets. The
aim should be to make pupils as comfortable as possible and to
encourage the development of good work habits which will serve them
well later in life. The material below on computer ergonomics in
schools is free and can be reproduced.
